What is an ionic compound?

Back

An ionic compound is a chemical compound composed of ions held together by electrostatic forces termed ionic bonding. It typically forms between metals and nonmetals.

Front

What is the general formula for ionic compounds formed with sulfur?

Back

The general formula for ionic compounds formed with sulfur is X2S, where X represents a metal.

Front

Which metal will form an ionic compound with sulfur?

Back

Lithium (Li) will form an ionic compound with sulfur.

Front

What are the attractive forces between particles in a substance?

Back

Attractive forces between particles can include ionic bonds, covalent bonds, and van der Waals forces, with varying strengths.

Front

How do you determine which substance has the weakest attractive forces?

Back

The substance with the weakest attractive forces typically has the lowest boiling or melting point.

Front

What is a covalent bond?

Back

A covalent bond is a type of chemical bond where two atoms share one or more pairs of electrons.

Front

How are covalent bonds formed?

Back

Covalent bonds are formed by the sharing of electrons between atoms.

Front

What is the Lewis Dot Structure?

Back

The Lewis Dot Structure is a diagram that shows the bonding between atoms of a molecule and the lone pairs of electrons that may exist.

Front

What is the correct Lewis Dot Structure for ammonia (NH3)?

Back

The Lewis Dot Structure for ammonia (NH3) shows nitrogen in the center with three hydrogen atoms bonded to it and one lone pair of electrons on nitrogen.

Front

What is a polar covalent bond?

Back

A polar covalent bond is a type of bond that occurs when two atoms with different electronegativities share electrons unequally.
