Ch 5 20 Q - IE, EA, EN

Front

What is electronegativity?

Back

The relative attraction for electrons that are being shared with another atom.

Front

What is the likely behavior of an element with an electron configuration ending in p5?

Back

It is most likely to gain one electron.

Front

What happens to the difficulty of removing electrons from an atom as more electrons are removed?

Back

Generally, each electron removed from an atom becomes more and more difficult and requires more and more energy.

Front

How does the first ionization energy of metals compare to nonmetals?

Back

Generally, metals have a lower first ionization energy than nonmetals.

Front

What is the trend for first ionization energy, electron affinity, and electronegativity when moving from left to right across a period?

Back

All are Lower --> Higher.

Front

Define first ionization energy.

Back

The energy required to remove the outermost electron from a neutral atom.

Front

What is electron affinity?

Back

The energy change that occurs when an electron is added to a neutral atom.

Front

What is the trend in electron affinity across a period?

Back

Generally increases from left to right across a period.

Front

What is the significance of noble gas configuration in relation to ionization energy?

Back

Electrons become more difficult to remove once a noble gas configuration is reached.

Front

What is the relationship between atomic size and ionization energy?

Back

Larger atoms generally have a lower first ionization energy than smaller atoms.
