Mass, electric charge, and internal structure.
number of neutrons, the number of protons is constant
It is because that they have a different number of protons and neutrons and electrons.
The sodium ion has less electrons than protons whereas the sodium atom has an equal amount of protons and electrons
Protons, neutrons, and electrons can form any type of atom on the Periodic Table of Elements.The amount of protons determine what type of element an atom is.If the number of neutrons differ from the stable amount it should have, the atom is known as an isotope.If the amount of electrons differ from the amount of protons, the atom is known as an ion.
18 protons 18 electrons 22 neutrons
They have the same number of protons and electrons.
Isotopes differ by the number of protons.
Electrons are very tiny compared to protons and neutrons. Electrons carry a negative charge, while protons are positive and neutrons are neutral.
Neutrons. If the differ in electrons they are not neutral and if they differ in protons then they are no longer the same element as the number of protons determines the name of the element.
It is because that they have a different number of protons and neutrons and electrons.
By number of protons/electrons.

Positively charged objects have more protons than electrons. Negatively charged objects have more electrons than protons.
No. Atoms differ in the number of protons, neutrons, and electrons.
As I remember neutrons and protons weight something similar, electrons have a far smaller mass which is negligable in comparison to the weight of protons.
All have spin one-half. Protons have a charge of positive one; electrons, negative one; neutrons, neutral. Protons and neutrons have about the same mass; electrons are much less massive. Protons and neutrons have an internal structure -- ie, they are composed of quarks -- while electrons are just themselves. The first two are "hadrons" and the latter is a "lepton."
No. Isotopes have the same atomic number, protons and electrons. They have different neutrons.
