Atomic Structure

What is the relationship between the number of protons and the atomic number?

As the number of protons increases by 1, the atomic number increases by 1

As you add protons, what pattern do you notice about the periodic table?

The elements are ordered from left to right across the periodic table by increasing atomic number.

What is the relationship between the number of electrons and the charge of the atom?

The relationship between the number of electrons and the charge of the atom is when you add an electron, the charge of the atom decreases; however, when you subtract an electron, the charge of the atom increases.

What is the relationship between the number of protons and the charge of the atom?

The relationship between the number of protons and the charge of the atom is when you add a proton, the charge of the atom increases; however, when you subtract a proton, the charge of an atom decreases.

An atom becomes unstable when there are too many or not enough (protons, neutrons, electrons).

neutrons

An atom becomes charged when the number of (protons, neutrons, electrons) does not equal the number of (protons, neutrons, electrons).

neutrons and electrons

The addition or removal of (protons, neutrons, electrons) causes the element name to change.

protons

Atomic mass is equal to the number of (protons, neutrons, electrons) plus the number of (protons, neutrons, electrons).

protons and neutrons

atomic number

the number of protons in the nucleus of an atom

mass number

the sum of the number of neutrons and protons in an atomic nucleus
