Front

What is a valence electron?

Back

Electrons in the outermost energy level.

Front

What is the maximum number of electrons in the 3rd energy level?

Back

18 electrons.

Front

What is the significance of the noble gases in electron configurations?

Back

They have full outer electron shells, making them stable and unreactive.

Front

What is the general trend of electronegativity in the periodic table?

Back

Electronegativity increases across a period and decreases down a group.

Front

What is the difference between an atom and an ion?

Back

An atom is neutral, while an ion has a net charge due to loss or gain of electrons.

Front

What does the term 'orbital' refer to in chemistry?

Back

An orbital is a region in an atom where there is a high probability of finding electrons.
