What is ionization energy?

Back

Ionization energy is the energy required to remove an electron from an atom in its gaseous state.

Front

How does ionization energy change across a period in the periodic table?

Back

Ionization energy increases from left to right across a period.

Front

What happens when metals react with non-metals?

Back

Metals lose electrons and form cations when they react with non-metals.

Front

What do nonmetals tend to do during chemical reactions?

Back

Nonmetals tend to gain electrons and form anions.

Front

What is a physical characteristic of metals?

Back

Metals have luster (shine).

Front

What is the electron configuration for Magnesium?

Back

1s² 2s² 2p⁶ 3s².

Front

What is the trend in ionization energy as you move down a group in the periodic table?

Back

Ionization energy generally decreases as you move down a group.

Front

What is the difference between cations and anions?

Back

Cations are positively charged ions formed by losing electrons, while anions are negatively charged ions formed by gaining electrons.

Front

What is the significance of the octet rule in chemistry?

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 general trend of electronegativity across a period?

Back

Electronegativity increases from left to right across a period.
