23-24 1st Semester Honors Chemistry Review

Front

What is the characteristic of a gas?

Back

A gas has fast-moving particles.

Front

According to the octet rule, how many valence electrons do most elements need to be stable?

Back

Most elements need 8 valence electrons to be stable.

Front

What is the name of the compound SO₂?

Back

Sulfur Dioxide.

Front

What type of bond involves the transfer of an electron from one atom to another?

Back

Ionic bond.

Front

How do you read the volume in a graduated cylinder?

Back

The volume is read at the bottom of the meniscus; for example, 23.7 mL.

Front

Define the term 'ionic bond'.

Back

An ionic bond is a chemical bond formed through the transfer of one or more electrons from one atom to another.

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 8 electrons.

Front

What is the difference between polar and non-polar covalent bonds?

Back

Polar covalent bonds involve unequal sharing of electrons, while non-polar covalent bonds involve equal sharing.

Front

What is the significance of the meniscus in measuring liquid volume?

Back

The meniscus is the curve at the surface of a liquid, and the volume is measured at the lowest point of this curve.

Front

What is the formula for calculating density?

Back

Density = Mass/Volume.
