The mass number is the total number of protons and neutrons in contains. Atomic mass is the average of all the masses of all the atoms components. What is the name of each of the following elements, and classify it as a metal, a nonmetal, or a metalloid: Na, Ba, Ca, La, Ti, Al, As, At, Ar. Isotopes - An isotope of a chemical element is an atom that has a different number of neutrons (that is, a greater or lesser atomic mass) than the standard for that element. The atomic number is the number of protons in an atom's nucleus. Ions - An ion is an atom or molecule that has a net electrical charge.

E = element's symbol; Atoms #p⁺ = #e^-

A = mass number ( #p⁺ + #n^o)

Z = atomic number ( #p⁺) Ions #p⁺ ≠ #e^-

Atoms With The Same Number Of Protons But Different Numbers Of Neutrons

Represents a sodium atom which always has 11 protons and in this case has a mass number of 23.
(Note: This means that there are 12 neutrons. 23 - 11 = 12)

Determining the number of electrons-

The number of electrons in an element can change. For a neutral atom, the number of protons is exactly equal to the number of electrons. So the number of electrons is the same as the atomic number. However, it is possible to remove electrons and not change the identity of an element. These are calledions. The charge on the ion tells you the number of electrons.

If the charge is positive, subtract that number from the atomic number to get the number of electrons. You have more protons.

If the charge is negative, add the amount of charge to the atomic number to get the number of electrons. You have more electrons.
