What is the composition of lighter elements in comparison with heavier element?
The lighter elements have less protons and neutrons than heavier ones. It really is as simple as that
It is in the stars that the heavier elements (basically, anything after element #2, helium) are made.
Curium is one of the transuranic elements.
Almost all solid elements are heavier than air. This is why these elements do not float under normal atmospheric situations.
Sun's composition: 70 percent hydrogen; 28 percent helium; 2 percent heavier elements by mass
Heavier elements - mainly, elements with an atomic number after that of iron - will only fuse at very high temperatures, mainly in supernovae.
About 75% hydrogen and 25% helium, with some traces of heavier elements.
What has a heavier element formed by fusion and has a massive star?
Hydrogen (element #1), helium (element #2), small amounts of lithium (element #3), and perhaps insignificant amounts of heavier elements.
EVERYTHING except hydrogen is heavier than helium. Helium is the second-lightest element.
All the elements with an atomic number greater than 79 are heavier than gold.
The fusion of hydrogen into helium and then to other elements - up to iron - release energy. This energy pushes against the gravitational attraction. The formation of atoms of iron and heavier elements nuclear fusion requires energy. There is, therefore, nothing to prevent the star collapsing in on itself under its own gravity. The heavier elements are produced only during supernovae.
Concrete is a heterogeneous mixture. It has a no uniform composition of heavier elements that are later mixed to become evenly distributed as possible. But it is still going to be heterogeneous.

Will there be any stable elements above the elements currently on the periodic table If yes is it just a matter of adding P - N - E to a current atom?
Probably not. As of 2013, the last known element is #118. It is possible that additional elements will be discovered after that one. The heaviest stable element is lead, element #82. It is unlikely that any heavier element will be stable. In general, the tendency is for heavier elements to be less stable.
It is believed this was how the universe formed. Hydrogen fuses to form all the other heavier elements on the periodic table up to Element number 92
Technetium, Promethium, and all elements heavier than Bismuth.
Elements with no stable isotopes include technetium (element 43) and promethium (element 61) and all elements heavier than lead (elements 83 and higher). Bismuth, element 83, is virtually stable with an extremely long half life of 1.9 x 1019 years.
All of them. There are no elements lighter than hydrogen. It has only two atomic particles, and you cannot have an element with less.
No, stars the size of the sun cannot produce any element heavier than oxygen
There are as many as 17 elements which are denser (and therefore heavier) than gold. Most of them are transuranic elements, almost all of which have a half-life measured in fractions of a second. The densest of the non-transuranic elements is osmium, which is about 17% heavier than gold. It is closely followed by iridium, then platinum and rhenium.
Supernova are responsible for every element in the Universe heavier than iron.
No, even the lightest element, hydrogen, has three isotopes.
Technetium, Promethium, and all elements heavier then Bismuth.
Hydrogen. This is also the lightest of all elements. All artificial elements are from 2 to about 300 times heavier than hydrogen.
How is energy released in stars and how does this effect the composition of elements in the universe?
Energy is released by fusion of elements to heavier elements, i.e. fusion of hydrogen to helium in the sun's core. I'm not sure what you mean by the 'composition of elements', but the hydrogen that our sun, like billions of other main sequence stars, is fusing right now is the leftover hydrogen from the Big Bang which, in billions of years' time, will eventually run out, and stars will have to fuse heavier elements, going… Read More
Fission is the process of taking a heavy element and splitting it into two or more smaller elements. Whereas fusion is the process of forming a heavier element by fusing two or more smaller elements.
When two smaller elements undergo fusion to form a heavier element. The combined mass of the two elements prior to fusion is less than the resulting mass of the heavier element created. This "mass deficit" is released as energy and can be calculated by the infamous E=mc2
It depends on the element. Some synthetic elements can be made by bombarding the nucleus of a lighter element with protons or alpha particles. The heavier synthetic elements are made by colliding atomic nuclei with one another.
Heavier elements are formed from hydrogen, the most abundant element in the universe, through a process called nuclear fusion. There are machines or structures in the universe that do this, and we call them stars. It is the process within stars, stellar nucleosynthesis, that allows heavier elements to be created up through iron. Elements heavier than iron are formed in supernova events. Use the links below to learn more.
All elements heavier than hydrogen can be formed by fusion, given enough energy.
Like other stars, Vega is primarily hydrogen and helium. In fact is particularly low in any elements heavier than helium.
Every element has a specific amount of protons and neutrons in its nuclues. If an atom has more protons and neutrons than another element, it is heavier.
Same as Earth, but in different proportions. Hydrogen is usually the most common element in stars, followed by helium, and smaller amounts of the heavier elements.
The heavier elements are created when stars go Super Nova. In that final moment when the gravity of a collapsing Star over comes the ability to Fuse iron into the next element, Nuclear Fusion once again takes place in the core and 1 creates the heavier elements gold zinc etc and 2 one of the most dazzling displays the Universe has to offer.
Most stars are predominantly hydrogen, with some helium and other heavier elements mixed in.
Arsenic is an element. It is made (like all elements heavier than helium) by fusion reactions inside stars.
Hydrogen and helium; those two elements are the fuel for the stars. First they fuse hydrogen to helium, later they fuse helium to heavier elements.
The most common element in the Universe - and in most stars - is hydrogen. Stars have smaller amounts of helium, and still smaller amounts of "metals" (heavier elements). Some stars may have burnt out their hydrogen, and consist mainly of helium and heavier elements. It really depends on the star's stage in its life cycle.
An element has no size - an atom is the particle of an element, and the molecule is the particle of a compound, or a collection of atoms. Atoms of an element would be smaller than molecules formed using that element or similar elements. NOTE 1 : The atoms of one element can form molecules, such as oxygen (O2) and ozone (O3). NOTE 2 : An atom of a heavier element can have greater mass… Read More
In general, the heavier elements have more neutrons and will end up as being denser. Osmium is the densist natural element.
All elements have radioactive isotopes. Add a couple of hundred neutrons, and any stable element becomes radioactive. Technetium, promethium, and anything heavier than bismuth (element 83) will have radioactive decay. radio active elements can be uranium,radium,thorium,polonium,actinium etc.usually all elements of atomic number higher than 82 show radioactivity.
No, isotopes of light elements exist as well. For example, there are several isotopes of the lightest element, hydrogen. No, even the lightest element (hydrogen (H)) has isotopes. These are called Deuterium and Tritium. All elements have isotopes but some of them are very unstable and have disappeared in nature over time.
No, Gold and several other elements have only one stable isotope, Promethium & Technetium as well as all elements heavier than Bismuth have no stable isotopes.
Young stars burn hydrogen (the lightest element), converting it into helium. Later they may convert helium into heavier elements.
Stars are mainly made of Hydrogen, which by fusion makes helium, and some heavier elements. Ordinary stars cannot make anything heavier than iron, but in a supernova, can develop high temperatures and for sufficient time, to make heavier elements. This is known as Nucleosynthesis. There are exceptions however, Carbon cannot be made in an ordinary star such as our Sun - for that you need a supernova.
Many stars are composed of helium (27%) and hydrogen (71%) and some other elements (2%) A star is made up of mostly hydrogen and some helium. As the star fuses more elements, there could also be heavier elements (such as oxygen, magnesium, and iron) in the star.
Most stars consist mainly of hydrogen, and (to a lesser degree) helium. This is the initial composition; after the star burns up its fuel, it will consist mainly of heavier elements.
The process in which lighter elements stick together to create heavier elements is known as fusion. This is the process that will be used in the synthesis of a heavier atomic nuclei.
What an interesting question. The answer is however complex. It is possible to make small amounts of some radioactive elements or radioactive isotopes of some elements in a laboratory (usually involving a nuclear pile or an accelerator). For instance the element Plutonium is made this way. (Other radioactive elements are produced naturally by the radioactive decay of heavier radioactive elements) However, making a radioactive element or isotope from scratch requires the application of an enormous… Read More
Energy is liberated through fusion reactions, producing heavier and heavier elements. There are two transient elements heavier than iron which are produced by standard stellar nucleosynthesis, but these are short lived and decay into lighter elements. Iron is the heaviest element forged in the heart of a star via standard stellar evolution. All elements heavier than iron are the byproduct of a supernova, wherein atomic nuclei are smashed together with such force energy is consumed… Read More
Although mainly hydrogen, the composition of stars can vary quite a bit from star to star. It depends on what materials were around during the formation of the star that determines the composition, which would have been dictated by what had been there previously. Large stars with high masses have relatively short life spans, but towards the end of their life they enter into phases where heavier elements are used as fuel, producing heavier elements… Read More
