Exam 2: Structure of the Atom

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

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

The electron binding energy is stronger when

The component of the nucleus that has mass but no electrical charge is the

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

The three fundamental particles of the atom are the

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

Atoms with the same atomic number and atomic mass number but have different energy within their nuclei are

Electron shells are the hard coating around the electron.

The force that holds the protons and neutrons together in the nucleus is the

If an atom has more protons than electrons it will

Each element has an unchanging number of protons.

The outermost shell of an atom can hold fewer than 8 electrons.

In the middle of the periodic table of elements there are elements that don't fit exactly into one of the eight groups.

A negative ion is

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

The atomic nucleus contains

If a particle strikes a nucleus with the same amount of energy as the atom's nuclear binding energy

The electron binding energy depends on

Atoms in each period have the same number of
