Back

Covalent bonds

Front

What type of bond occurs between a metal and a non-metal element?

Back

Ionic

Front

Malleability means __________.

Back

the ability to be hammered into a shape

Front

__________________ are the bonds that keep metals intact. These bonds are formed between the free valence electrons found surrounding the protons of adjacent metal nuclei.

Back

Metallic bonds

Front

What is a covalent bond?

Back

A bond formed when two atoms share one or more pairs of electrons.

Front

What is the main characteristic of ionic compounds?

Back

They typically form crystalline structures and have high melting and boiling points.

Front

What property of metals allows them to conduct electricity?

Back

The presence of free-moving electrons.

Front

Define electronegativity.

Back

The tendency of an atom to attract electrons in a chemical bond.

Front

What is the difference between a polar and nonpolar covalent bond?

Back

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