Periodic Trends and Classification

Front

What is ionization energy?

Back

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

Front

Which element has a lower ionization energy than Scandium (Sc)?

Back

Calcium (Ca) has a lower ionization energy than Scandium.

Front

What does high electronegativity indicate about an atom?

Back

Atoms with high electronegativity hold on to their electrons more tightly.

Front

What is electronegativity?

Back

Electronegativity is a measure of how good an atom is at attracting electrons.

Front

What happens to atomic radius as you move down a group in the periodic table?

Back

The atomic radius increases as you move down a group in the periodic table.

Front

What is the trend of metallic character in the periodic table?

Back

Metallic character increases as you move down a group in the periodic table.

Front

What does valency refer to in chemistry?

Back

Valency refers to the ability of an atom to bond with other atoms, which does not increase while moving down a group.

Front

How does the number of electron shells change in the periodic table?

Back

The number of electron shells increases as you move down a group in the periodic table.

Front

What is the relationship between ionization energy and electronegativity?

Back

Generally, elements with high electronegativity also have high ionization energy.

Front

What is the trend of ionization energy across a period?

Back

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