Periodic Trends Practice

Front

Which atom is larger: Br or Cl?

Back

Br is larger than Cl because atomic size increases down a group in the periodic table.

Front

Which atom is a halogen?

Back

Cl is a halogen, located in Group 17 of the periodic table.

Front

Does electronegativity increase or decrease from left to right across the periodic table?

Back

Electronegativity increases from left to right across the periodic table.

Front

Which atom has the greater Ionization Energy: P or Ar?

Back

Ar has a greater Ionization Energy than P because it is further to the right in the periodic table.

Front

Which atom has the greater Ionization Energy: Ca or Ba?

Back

Ca has a greater Ionization Energy than Ba because it is higher up in the periodic table.

Front

Define atomic radius.

Back

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

Front

What is the trend of atomic radius in the periodic table?

Back

Atomic radius decreases from left to right across a period and increases down a group.

Front

What is ionization energy?

Back

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

Front

What is the trend of ionization energy in the periodic table?

Back

Ionization energy increases from left to right across a period and decreases down a group.

Front

Define electronegativity.

Back

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