Ionization Energy & E- Affinity

Front

What is Ionization Energy?

Back

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

Front

What is Electron Affinity?

Back

The amount of energy released when an electron is added to a neutral atom in the gaseous state.

Front

Which element has a lower ionization energy: Lithium, Sodium, or Cesium?

Back

Cesium has the lowest ionization energy.

Front

Order the following elements by increasing ionization energy: Calcium, Iron, Copper.

Back

Calcium, Iron, Copper.

Front

Why does ionization energy decrease as you go down a group in the periodic table?

Back

Outer electrons are further away from the nucleus, feel less pull from the nucleus, and are easier to remove.

Front

Which element has a greater need for electrons: Calcium or Barium?

Back

Calcium has a greater need for electrons.

Front

Which element has a greater electron affinity: Phosphorus or Chlorine?

Back

Chlorine has a greater electron affinity.

Front

What trend is observed in ionization energy across a period?

Back

Ionization energy generally increases across a period from left to right.

Front

What is the relationship between atomic size and ionization energy?

Back

As atomic size increases, ionization energy decreases.

Front

Define the term 'noble gas configuration'.

Back

A stable electron configuration that resembles that of the noble gases, typically having a full outer shell.
