In alpha and beta decay the parent elements is always a different element from the daughter element?
true
What else can I help you with?
When a nucleus undergoes alpha decay the daughter element always has less charge than the parent?
No, the daughter element after alpha decay has less atomic number than the parent (reducing charge), but the total charge (protons) in the nucleus remains the same. The daughter element gains stability by emitting an alpha particle, which consists of two protons and two neutrons.
What are Dalton points in the atomic theory?
daltons atomic postulations stated that: * Elements are made of tiny particles called atoms. * All atoms of a given element are identical. * The atoms of a given element are different from those of any other element; the atoms of different elements can be distinguished from one another by their respective relative weights. * Atoms of one element can combine with atoms of other elements to form chemical compounds; a given compound always has the same relative numbers of types of atoms. * Atoms cannot be created, divided into smaller particles, nor destroyed in the chemical process; a chemical reaction simply changes the way atoms are grouped together.
Can nuclear reactions create new elements?
When atoms undergo nuclear fission , the result is always two different atoms very much less massive than the parent. For fusion, the resulting atom or atoms are usually of a different element, but not always.Part of the trick to understanding this is that in these types of reactions, the numbers of protons and neutrons going in has to be the same as the number coming out, though some of the decay reactions other than fission turn a proton into a neutron or the other way around. Another thing to remember is that the number of protons determines the element of an atom.FusionWhen we fuse atoms, we are taking neutrons and protons from the nuclei of the two atoms and putting them into a single daughter atom. A typical example of a fusion reaction is: 12H + 12H --> 23He + 01nIn this reaction, the symbol 12H represents hydrogen (atomic symbol H), with the 2 indicating the number of protons plus the number of neutrons, and 1 being the number of protons; this can be read as hydrogen-2. Similarly, 23He is helium-3, and 01n is a silly way to represent a neutron, but it makes the balancing of the equation obvious.We might imagine that fusion always produces an atom of a new element, but this is not the case. It is possible to fuse two helium atoms to produce a heavier helium atom plus a pair of protons, which are essentially hydrogen atoms. A reaction follows:23He + 23He --> 24He + 11p + 11pSo two atoms of helium are combined to produce one atom of helium plus a couple of particles.FissionAtoms have to be pretty heavy to undergo fission, which is what happens when one atom splits into two atoms. Again, the number of protons is kept the same in fission, as is the number of neutrons. But here, the parent atom has a number of protons, and the daughter atoms combine to have that number of protons. Clearly fission cannot happen without the daughter atoms being entirely different from the parent. An example equation for fission is as follows (but bear in mind that the uranium fission equation can take many different forms with many different results): 92235U --> 3692 Kr + 56140Ba + 2 01nOther types of decayThere are many other types of nuclear decay with a single atom undergoing some sort of change to produce another single atom. In most of them, the daughter atom is of a different element than the parent, but this is not true in all cases. In decay involving producing only a gamma ray, for example, there is only a slight change in the mass of the atom. For example: 99mTc --> 99Tc + gamma
What Are The Three Elements That Are Always Present?
The three elements that are always present are hydrogen, carbon, and oxygen. These elements are essential for the formation of organic compounds and are commonly found in living organisms, as well as inorganic substances.
What does a transmutation reaction always have to involve?
A transmutation reaction always involves a change in the identity of the atoms involved, resulting in the formation of different elements. This can be achieved through processes like radioactive decay or nuclear fusion.
In alpha decay the parent element and the daughter element can be different isotopes of the same element but in beta decay the parent and daughter element are always the same?
No. In both the cases the element would definitely change. As alpha particle comes out then the new element would have two less in atomic number where as in beta particle decay the new element will have one higher in atomic number.
Are all elements made up of different elements combined?
No, each element is in basic form and are always only made up from themselves. When elements are combined this is a compound.
Can atoms of different elements have the same number of protons be from the same element?
No. Each type of atom (element) has its own unique number of protons, which is called the atomic number. Atoms of the same element will always have the same atomic number (number of protons). Atoms of different elements will never have the same atomic number (number of protons).
Which characteristics of an atom always varies among atoms of different elements?
The number of protons is always different. Depending on isotopes, the number of neutrons and atomic mass can be the same as another element. Electrons almost always are varying in number, making elemental ions have the same number of them.
Atoms of different elements always contain different number of what?
well of protons, STOP CHEATING IN WIKIANSWERS AND DO YOUR WORK
Does a compound always contain the same element in the same proportions?
Yes, except that "element" should be pluralized; a compound always has at least two elements.
How do scientist tell the different between two isotopes of the same element?
scientists Can tell the difference between two isotopes of the same element because, isotopes of the same elements always have the same number of protons.
Can two different element have the same number of proton?
No, the number of protons determines the element. Each element has a unique number of protons in its nucleus, which is what defines its identity. If two elements had the same number of protons, they would be the same element.
Which element is always found in nature combined with with other elements?
magnesium :)
What happens when atoms form a covalent bond?
a) Must include a metal and a nonmetal b) Must be of different elements c) Are always of the same element d) Are always two metals Need Answer! :( D) Are always two metals. a) is for ionic compounds b) is for nonpolar covalent bonds c) same as nonpolar covalent bonds b) Must be of different elements:)
Can an atom of two different elements have the same mass number?
Yes. The mass number is basic to the different elements, even more useful than the atomic number. (Unless it is an isotope. Isotopes have a different amount of neutrons than the basic element atom which makes a difference in mass number too. So, a difference in mass numbers doesn't always mean it is a different element.)
Binary acids contain hydrogen and how many other elements?
one, and binary compounds don't always contain hydrogen, just 2 different elements
