Periodic Trends

Front

What is the atomic radius?

Back

The atomic radius is a measure of the size of an atom, defined as the distance from the nucleus to the outermost electron orbit.

Front

Which element has a larger atomic radius: Strontium or Zinc?

Back

Strontium has a larger atomic radius than Zinc.

Front

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

Back

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

Front

What trend is observed in atomic radius as you move across a period from left to right?

Back

Atomic radius decreases as you move across a period from left to right due to increased nuclear charge pulling electrons closer.

Front

What is electronegativity?

Back

Electronegativity is the ability of an atom to attract electrons in a chemical bond.

Front

Which element has a higher electronegativity: Carbon or Arsenic?

Back

Carbon has a higher electronegativity than Arsenic.

Front

What is ionization energy?

Back

Ionization energy is the amount of energy required to remove a valence electron from an atom.

Front

How does ionization energy change across a period?

Back

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

Front

How does ionization energy change down a group?

Back

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

Front

What is the relationship between electronegativity and ionization energy?

Back

Elements with high electronegativity typically have high ionization energy.
