Front

What type of compounds are H2O, Cl2, and NH3?

Back

They are all covalent compounds.

Front

What is the primary characteristic of a metallic bond?

Back

Delocalized electrons moving freely among a lattice of metal ions.

Front

What is the formula for Potassium Nitride?

Back

K3N.

Front

Which pair of elements will MOST LIKELY form an ionic bond?

Back

Magnesium and sulfur.

Front

How is a covalent molecule formed?

Back

An atom of an element with atomic number 9 reacts with a sulfur atom.

Front

Define ionic bond.

Back

A bond formed through the transfer of electrons from one atom to another, resulting in the formation of charged ions.

Front

What is a covalent bond?

Back

A bond formed by the sharing of electron pairs between atoms.

Front

What is the octet rule?

Back

Atoms tend to gain, lose, or share electrons to achieve a full outer shell of eight electrons.

Front

What is the difference between polar and nonpolar covalent bonds?

Back

Polar covalent bonds have unequal sharing of electrons, while nonpolar covalent bonds have equal sharing.

Front

What is electronegativity?

Back

A measure of the tendency of an atom to attract a bonding pair of electrons.
