An ionic bond results from electrical attraction between _____

• cations and anions

• atoms

• dipoles

• orbital

A nonpolar covalent bond is unlikely when two atoms of different elements join because the atoms are likely to differ in

• density

• state of matter

• electronegativity

• polarity

Bond length is the distance between two bonded atoms at

• their minimum potential energy

• heir maximum potential energy

• their maximum kinetic energy.

• one-half the diameter of the electron cloud.

To draw a Lewis structure, it is not necessary to know

• which atoms are in the molecule

• bond energies

• the number of valence electrons for each atom

• the number of atoms in the molecule

For multiple covalent bonds to form in molecules, the molecules must contain carbon, nitrogen, or

• chlorine

• hydrogen

• oxygen

• helium

The principle that states that atoms tend to form compounds in which each atom has eight electrons in its highest occupied energy level is called the___

• rule of eights.

• configuration rule

• Avogadro principle

• octet rule

A covalent bond in which the bonded atoms have an unequal attraction for the shared electrons is called a(n) _______________________.

A covalent bond between two atoms produced by sharing two pairs of electrons is called a(n) _______________________.

The energy required to break a chemical bond and form neutral isolated atoms is called _______________________.
