HChem 1st Semester Exam Review - 5

Front

What is ionization energy?

Back

The energy required to remove an electron from an atom or ion in its gaseous state.

Front

What is the trend of ionization energy across a period?

Back

Ionization energy generally increases across a period from left to right due to increasing nuclear charge.

Front

What is the trend of ionization energy down a group?

Back

Ionization energy generally decreases down a group due to increased distance between the nucleus and the outermost electrons.

Front

What is the name for NaH?

Back

Sodium hydride.

Front

What is the name of NF3?

Back

Nitrogen trifluoride.

Front

What is the formula for iron (II) carbonate?

Back

FeCO3.

Front

What is the trend of atomic radius across a period?

Back

Atomic radius generally decreases across a period due to increasing nuclear charge pulling electrons closer.

Front

What is the trend of atomic radius down a group?

Back

Atomic radius generally increases down a group due to the addition of electron shells.

Front

What is the significance of electronegativity?

Back

Electronegativity is a measure of an atom's ability to attract and hold onto electrons in a chemical bond.

Front

What is the trend of electronegativity across a period?

Back

Electronegativity generally increases across a period from left to right.
