Front

Ionic compounds tend to be _________ whereas covalent compounds tend to be ______ or _____

Back

solids // liquids or gases

Front

Ionic Compounds are formed by the attraction of positive to negative

Back

True

Front

Why does K become positive when it bonds to Cl to form KCl?

Back

Because it loses an electron to have a full valence shell

Front

The octet rule means that all valence shells want to have the number......

Back

8

Front

Which does NOT describe covalent compounds?

Back

High melting points

Front

What is an ionic bond?

Back

A chemical bond formed by the electrostatic attraction between oppositely charged ions.

Front

What is a covalent bond?

Back

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

Front

What are metallic bonds?

Back

Chemical bonds that occur between metal atoms, characterized by a 'sea of electrons' that are free to move.

Front

What is the octet rule?

Back

Atoms tend to gain, lose, or share electrons to achieve a full outer shell of 8 electrons.

Front

What are the properties of ionic compounds?

Back

High melting and boiling points, solid at room temperature, and conduct electricity when dissolved in water.
