It is called an isotope.
Atoms of the same element cannot have different numbers of protons. Different numbers of protons mean different elements. An atom with the a different number of neutrons is called an isotope.
This is not possible. The number of protons identifies an element, and all of the atoms of the same element have the same number of protons. The atoms of an element can, however, have different numbers of neutrons, and they are called isotopes.
They are called Isotopes
Each element has a unique number of protons. If another atom has the same number of protons as that element, it is the same element.
Number of protons in in an element denote the type of element. So you identify element on the number of protons in it. Protons being positively charged can not sit together in a nucleus. They will repel each other. So you do not have an element in which only 2 or more protons and no neutrons are there.It means neutrons act as binding material in an element. So usually equal or more neutrons are there in an element. If same number of neutrons are there in nucleus but different number of protons, then it is no more a same but different element. An element in which different number of neutrons are there are called as Isotope. All element have got one or more Isotopes. So there 'physical' properties would differ but not 'chemical' property.
Not all atoms have an equal number of protons and neutrons. They can, but they don't have to. Helium, for example, has two of each, but carbon (always with 6 protons) can have 6, 7, or even 8 neutrons. The more neutrons, the more likely it is to be radioactive. The number of protons and neutrons gives the atomic weight of an atom. All of the various amounts of neutrons that an element can have are called isotopes of that element.
Isotopes.
They are called isotopes,
We call them isotopes. They are different from physical behavior.
No, atoms of the same element have the same number of protons. Atoms of the same element with different numbers of neutrons are called isotopes.
istope
If an atom of the same element has the same number of protons but a different number of neutrons, then they are isotopes.
