Periodic Trends

Front

What is ionization energy?

Back

Ionization energy is the energy required to remove an electron from an atom in its gaseous state.

Front

Which element has the greater ionization energy: Magnesium, Phosphorus, Barium, or Nitrogen?

Back

Nitrogen has the greater ionization energy.

Front

As you move across a period in the periodic table, what happens to the size of atoms?

Back

Atoms tend to get smaller because the atoms have more protons.

Front

What characterizes noble gases?

Back

Noble gases are characterized by having a full valence shell of electrons.

Front

How are elements arranged in the periodic table?

Back

Elements are arranged by similar physical and chemical properties.

Front

Which of the following has the highest ionic radius: Li⁺, Na⁺, K⁺, or Rb⁺?

Back

Rb⁺ has the highest ionic radius.

Front

What is the trend in electronegativity as you move across a period?

Back

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

Front

What is the trend 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 energy levels.

Front

Define electronegativity.

Back

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

Front

What happens to the reactivity of metals as you move down a group?

Back

The reactivity of metals increases as you move down a group.
