Simple Ionic compounds

Front

What is an ionic compound?

Back

An ionic compound is a chemical compound composed of ions held together by electrostatic forces termed ionic bonding. They typically form between metals and non-metals.

Front

Which of the following is not an ionic compound: NaOH, KBr, NO2, LiCl2?

Back

NO2 is not an ionic compound; it is a covalent compound.

Front

What are anions?

Back

Anions are negatively charged ions formed when non-metals gain electrons.

Front

What is the charge on the hydroxide ion (OH-)?

Back

The charge on the hydroxide ion is -1.

Front

When naming ionic compounds, what is the general rule for the ending of the name?

Back

Ionic compounds typically end in 'ide' unless they contain a polyatomic ion.

Front

What is the formula for combining Al3+ and Cl- ions?

Back

The proper chemical formula is AlCl3.

Front

What is a cation?

Back

A cation is a positively charged ion formed when a metal loses electrons.

Front

What is the significance of the octet rule in ionic bonding?

Back

The octet rule states that atoms tend to gain, lose, or share electrons to achieve a full outer shell of eight electrons, leading to the formation of stable ionic compounds.

Front

What is the formula for sodium chloride?

Back

The formula for sodium chloride is NaCl.

Front

How do you determine the charge of a monatomic ion?

Back

The charge of a monatomic ion can be determined by its position in the periodic table; metals typically lose electrons and become cations, while non-metals gain electrons and become anions.
