PERIODIC TRENDS

Front

What is Electronegativity?

Back

The ability of an atom to attract/accept electrons.

Front

What is the definition of Ionization?

Back

The energy required to remove electrons from an atom.

Front

What happens to atomic size as you move across the periodic table?

Back

Atoms tend to get smaller.

Front

Why do atoms get smaller as you move across the periodic table?

Back

Because the atoms have more protons, increasing the attraction to electrons.

Front

What is the trend of atomic radius from left to right across a period?

Back

The atomic radius decreases.

Front

What causes the decrease in atomic radius across a period?

Back

The increase in the number of protons, which increases the attraction to electrons.

Front

Which element has the largest atomic radius in Group 18?

Back

Rn (Radon).

Front

What is the atomic radius?

Back

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

Front

How does ionization energy change across a period?

Back

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

Front

What is the relationship between electronegativity and ionization energy?

Back

Generally, as electronegativity increases, ionization energy also increases.
