Atomic Radius, Forces of Attraction, and Ionization Energy

Front

What is atomic radius?

Back

The atomic radius is the distance from the nucleus of an atom to the outermost shell of electrons.

Front

How does the number of protons affect the force of attraction in an atom?

Back

More protons in the nucleus increase the force of attraction between the nucleus and the valence electrons.

Front

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 as you move from left to right across a period.

Front

What happens to the force of attraction as the distance between electrons and protons increases?

Back

The force of attraction decreases as the distance between electrons and protons increases.

Front

Which group of elements has the highest ionization energy?

Back

Noble gases (Group 18) generally have the highest ionization energy.

Front

What is the trend of atomic radius as you move down a group in the periodic table?

Back

The atomic radius increases as you move down a group due to the addition of electron shells.

Front

What is the trend of atomic radius as you move across a period?

Back

The atomic radius decreases as you move from left to right across a period.

Front

What is the relationship between atomic radius and ionization energy?

Back

Generally, as atomic radius decreases, ionization energy increases.

Front

Which element has a larger atomic radius: Lithium (Li) or Fluorine (F)?

Back

Lithium (Li) has a larger atomic radius than Fluorine (F).
