Chemistry Ch 6 Full Review

Front

How does an atom become a positive ion?

Back

An atom becomes a positive ion by losing one or more electrons.

Front

What type of bonds hold atoms of molecules together?

Back

Covalent bonds hold atoms of molecules together.

Front

Which compounds have relatively low melting points and boiling points?

Back

Molecular compounds have relatively low melting points and boiling points.

Front

How does an atom become an ion with a -2 charge?

Back

An atom becomes an ion with a -2 charge by gaining 2 electrons.

Front

What is an ion?

Back

An ion is an atom or molecule that has a net electrical charge due to the loss or gain of one or more electrons.

Front

What are ionic bonds?

Back

Ionic bonds are formed when one atom transfers electrons to another atom, resulting in the attraction between oppositely charged ions.

Front

What are covalent bonds?

Back

Covalent bonds are formed when two atoms share one or more pairs of electrons.

Front

What is the difference between ionic and covalent compounds?

Back

Ionic compounds are formed from the electrostatic attraction between ions, while covalent compounds are formed from shared electrons.

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 are molecular compounds?

Back

Molecular compounds are chemical compounds whose simplest units are molecules, formed by covalent bonds.
