Chemistry Ch 5 Review - 50 Q

Front

What happens to ionization energy as more electrons are removed from an atom?

Back

Ionization energy increases with each subsequent electron removed.

Front

What is the most likely charge of an ion made from an element in Group 17?

Back

-1

Front

How many electrons must be gained or lost to make a noble gas atom stable?

Back

0

Front

What is the most likely charge of an ion made from an element in Group 18?

Back

They don't make ions.

Front

What is the group number of the alkali metals in the periodic table?

Back

1

Front

Define ionization energy.

Back

The energy required to remove an electron from an atom.

Front

What is the significance of noble gases in terms of electron configuration?

Back

Noble gases have a full valence shell, making them stable and unreactive.

Front

Explain the trend of ionization energy across a period in the periodic table.

Back

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

Front

Explain the trend of ionization energy down a group in the periodic table.

Back

Ionization energy generally decreases down a group due to increased distance from the nucleus and electron shielding.
