REVIEW - ATOMIC SIZE

Front

What happens to the energy of an electron as it moves farther from the nucleus?

Back

The energy of the electron increases.

Front

What is the term for the blocking of nuclear attraction for valence electrons?

Back

Shielding effect.

Front

How does the number of protons in an atom affect the pull on electrons?

Back

The more protons there are, the stronger the pull on the electrons.

Front

How many groups are there on the periodic table and how are they arranged?

Back

There are 18 groups, and they are arranged vertically.

Front

Which element has the largest atomic radius: Potassium, Calcium, Nitrogen, or Oxygen?

Back

Potassium has the largest atomic radius.

Front

Define atomic radius.

Back

Atomic radius is the distance from the nucleus to the outermost shell of an electron.

Front

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

Back

Atomic size increases as you move down a group.

Front

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

Back

Atomic size decreases as you move from left to right across a period.

Front

What is ionization energy?

Back

Ionization energy is the energy required to remove an electron from an atom.

Front

How does shielding effect influence ionization energy?

Back

Increased shielding effect lowers ionization energy.
