When an atom is of the same atomic number, Atomic Mass, etc. to the one on the Periodic Table (Lets use Boron for example) Then B is the regular atom. But if you change the number of neutrons (from 6-to-7 or whatever number) ; because the number of protons never changes; you will get a different atomic mass, so an isotope is the atom with a different atomic mass. You write an isotope atom with the elements symbol and to the left of it you script (In the top left corner really small like an exponent) the new atomic mass. So in this case B would now be 12B
Isotope
When an atom of an element has a different number of neutrons.
an isotope is defined by an atom with the same number of protons, but a different number of neutrons
Neutrons
An isotope is where an atom has a different number of neutrons than what it should be.e.g.Gold has 79 protons and 118 neutrons = 197 nucleons.But some gold atoms are strange they only have 117 neutrons.They are isotopes.
Uranium neutral atom has 92 protons and electrons; the number of neutrons is different for each isotope.
An isotope will have the same number of protons, but a different number of neutrons than a given atom.
Isotope
When an atom of an element has a different number of neutrons.
An element is a class of substances An atom is the smallest possible piece of an element. An isotope is an electrically charged atom.
an isotope is defined by an atom with the same number of protons, but a different number of neutrons

Neutrons
The Neutron- An element with the same number of protons and electrons, but with a different number of neutrons per atom than the original element is called an "isotope". An isotope will have, for all intensive purposes, about the same chemical and physical properties as the original element. Isotopes are written as the element, followed by a dash, then the number of neutrons in one atom of that isotope (Carbon-13 is an isotope of carbon with 13 neutrons per atom)
An isotope has extra/fewer neutrons than the original atom. So if you know the isotope you can deduce the original atoms' formula.For Ca that would be:20 protons40 mass number
an isotope.
No, it becomes a different isotope. An element is defined solely by the number of protons.
