Front

What do families in the periodic table have in common?

Back

Families all have similar properties.

Front

What is Atomic Radius?

Back

Atomic Radius is the relative size of the atom's electron cloud.

Front

Which element in period 3 has an electron affinity of zero?

Back

Argon.

Front

Which element has a higher ionization energy than arsenic (As)?

Front

What are the two most reactive families on the periodic table?

Back

Halogens & Alkali metals.

Front

Define ionization energy.

Back

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

Front

What is electron affinity?

Back

Electron affinity is the energy change that occurs when an electron is added to a neutral atom.

Front

What are alkali metals?

Back

Alkali metals are the elements in Group 1 of the periodic table, known for being highly reactive.

Front

What are noble gases?

Back

Noble gases are the elements in Group 18 of the periodic table, known for their lack of reactivity.

Front

What is the periodic trend for atomic radius?

Back

Atomic radius generally increases down a group and decreases across a period.
