What else can I help you with?
There are elements found naturally in the universe?
yes oxygen is an element and it is naturally found in the universe
How many elements are found in the universe?
92
Which elements is found in the greatest number of substance?
The most abundant element in the universe is Hydrogen, making up about 75% of all matter.
Where can isotopes be found?
Isotopes can be found in any element. A definitive statement on an isotope is ' An Atom has a different number of neutrons'. The element that exhibits in large proportion two isotopes is chlorine. There is Chlorine-35 & Chlorine-37 The numbers being the atomic masses of of chlorine. The difference of '2' ( 37-35) is made up by a different number of neutrons. Chlorine-35 ; 17 protons, 18 neutrons and 17 electrons Chlorine-37 ; 17 protons. 20 neutrons and 17 electrons. The atomic Mass of Chlorine is given as 35.5 . This because there are 75% of Cl-35 atoms and 25% of Cl-37 atoms. NB Not all isotopes are Radio-Active, but some are!!!!!
How many number of elements found in naturally in the universe?
Today all elements up to atomic number 98 (including Cf) are considered as natural chemical elements.
Source of all elements in the universe?
Elements in the universe originate from various sources, including the Big Bang nucleosynthesis, stellar nucleosynthesis in the cores of stars, supernova explosions, and cosmic ray spallation. These processes create and distribute the elements found in the universe, ranging from hydrogen and helium to heavier elements like oxygen, carbon, and iron.
Who is responsible for discovery of elements?
Different people found different elements.
What matter in the universe is not formed from a combination of elements found on the periodic table?
Now the periodic table is limited to 118 elements.
There are 92 naturally occurring?
There are 92 naturally occurring elements on the periodic table. Each element is represented by its own unique chemical symbol, such as "H" for hydrogen or "O" for oxygen. These elements make up all matter in the universe.
Are all atoms alike?
No, atoms are not all alike. Atoms can have different numbers of protons, neutrons, and electrons, which influence their properties and behavior. This variability in atomic structure leads to the diversity of elements and compounds found in the universe.
Could elements only be found in earth?
No, elements exist throughout the universe, not just on Earth. Elements are the building blocks of matter and can be found in stars, planets, and other celestial bodies. They are fundamental to the composition of all known matter.
99 percent of the known matter in the universe?
is found in the form of hydrogen and helium. These elements were created during the Big Bang, and all other elements found in the universe were formed through processes like nuclear fusion in stars. Only a small fraction of the universe is made up of heavier elements like carbon, oxygen, and iron.
