Exam 2: Structure of the Atom

Atoms in each period have the same number of

The component of the nucleus that has a positive charge and mass is the

The electrons rotate around the nucleus at a single energy level.

The mass of an atom is primarily due to the mass of the

If an atom has more protons than electrons, it will

When an atom becomes negatively or positively charged it is usually due to a change in the number of

The atoms of the elements at the top of the periodic table of elements are the most complex.

The "plum pudding model" is associated with

Two or more atoms that bond together form a(n)

A compound consists of

A positive ion is

Except for the K shell, the maximum number of electrons that can be in the outermost shell of an atom is

How many neutrons does 73Li (lithium) have?

Atoms with different number of protons but the same combined number of protons and neutrons are

An ionic bond results in an electrically charged molecule or compound.

The earliest atomic theory based on an arrangement similar to the solar system is attributed to

The simplest form of the substances that form matter is the

The electrons stay in orbit around the nucleus because of

When the bond between two atoms is due to their sharing an outer-shell electron, this is called a

Atoms with the same number of protons but different number of neutrons are
