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.
Isotopes are atoms of the same elements with different number of neutrons.
atoms of different elements having same number of neutrons
No. Some may have different numbers of neutrons. Atoms of the same element (atoms with the same number of protons in the nucleus) may have different numbers of neutrons, and so will have different masses. As an example, chlorine is a mixture of different isotopes with some of the atoms having different neutrons numbers.
Different atoms and elements that have different number of protns, neutrons and electrons.Duh!
neutrons of all atoms are alike
elements are isotopes, when different atoms of the same element have different number of neutrons
Atoms that vary in the number of neutrons found in their nuclei are called isotopes. Isotopes of an element have the same number of protons but different numbers of neutrons, which can lead to variations in their atomic mass.
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.
number of neutrons = mass number - atomic number
because the neutrons have no charge
Atoms of all elements can have neutrons in them. Only the element hydrogen has an isotope whose atoms do not contain neutrons, but all other isotopes of hydrogen have neutrons in them. In the heavier elements the number of neutrons always exceeds the number of protons in the atom.
Atoms of the same element that have different numbers of neutrons are called isotopes. An isotope is known by its mass number, which is the sum of the protons and neutrons in its nucleus.
