Chemistry Semester 1 Final Review

Front

What happens to electrons during the formation of an ionic compound?

Back

Electrons are transferred from one atom to another.

Front

How many electrons does a neutral chromium (Cr) atom have?

Back

A neutral chromium (Cr) atom has 24 electrons.

Front

Which type of elements typically share electrons to form covalent bonds?

Back

Two nonmetals.

Front

What is the chemical name for SF6?

Back

Sulfur hexafluoride.

Front

What is the name of the substance CuCO3?

Back

Copper(II) carbonate.

Front

What is an ionic bond?

Back

An ionic bond is a chemical bond formed through the transfer of electrons from one atom to another, resulting in the attraction between oppositely charged ions.

Front

What is a covalent bond?

Back

A covalent bond is a chemical bond formed when two nonmetals share electrons.

Front

Define the term 'molecule'.

Back

A molecule is a group of two or more atoms bonded together by covalent bonds.

Front

What is the octet rule?

Back

The octet rule states that atoms tend to gain, lose, or share electrons to achieve a full outer shell of eight electrons.

Front

What is the difference between a metal and a nonmetal?

Back

Metals are typically good conductors of heat and electricity, while nonmetals are poor conductors and can be gases, liquids, or solids at room temperature.
