review - covalent bonding mini-test

If the atoms that share electrons have an unequal attraction for the electrons, the bond is called

• nonpolar

• polar

• ionic

• dipole

Nonpolar covalent bonds are not common because

• ions always form when atoms join

• dipoles are rare in nature

• one atom usually attracts electrons more strongly than the other

• the electrons usually remain equally distant from both atoms

A neutral group of atoms held together by covalent bonds is a

• molecular formula

• chemical formula

• molecule

• monoatomic ion

Elements that form multiple covalent bonds include

• oxygen

• carbon

• nitrogen

• all of the above

What is placed between resonance structures to indicate resonance?

• double-headed arrow

• single-headed arrow

• dots

• Lewis structure

When a polar molecule attracts the electron in a nonpolar molecule,

• an ionic bond forms

• a Lewis structure forms

• a crystal lattice forms

• a dipole is induced

What is the formula for dioxygen pentachloride?

• OCl₄

• O₂Cl₅

• O₅Cl₂

• O₄Cl

Why do most atoms form bonds?

• to be more stable by completing the octet

• to be less stable

• to add more electrons

• to carry out physical changes

If two covalently bonded atoms are identical, the bond is

• coordinate covalent

• polar covalent

• dipole covalent

• nonpolar covalent

What are shared in a covalent bond?

• ions

• Lewis structures

• dipoles

• electrons
