Periodic Trends Review

Front

What are nonmetals?

Back

Nonmetals are elements that typically lack the characteristics of metals. They are usually poor conductors of heat and electricity and can be gases, liquids, or brittle solids at room temperature.

Front

What is ionization energy?

Back

Ionization energy is the energy required to remove an electron from an atom in its gaseous state. It generally increases across a period and decreases down a group in the periodic table.

Front

How does atomic size change in the periodic table?

Back

Atomic size increases as you move down a group due to the addition of energy levels, and it decreases as you move from left to right across a period due to increased nuclear charge.

Front

What is electronegativity?

Back

Electronegativity is a measure of an atom's ability to attract and hold onto electrons in a chemical bond. It generally increases across a period and decreases down a group.

Front

Which element has a higher electronegativity: Nitrogen (N) or Carbon (C)?

Back

Nitrogen (N) has a higher electronegativity than Carbon (C).

Front

What trend does ionization energy follow in the periodic table?

Back

Ionization energy increases from left to right across a period and from bottom to top within a group.

Front

What are metalloids?

Back

Metalloids are elements that have properties intermediate between metals and nonmetals. They are typically semiconductors of electricity.

Front

What is the significance of noble gases in the periodic table?

Back

Noble gases are elements in Group 18 that are characterized by their lack of reactivity due to having a full valence shell of electrons.

Front

What happens to the number of energy levels as you move down a group in the periodic table?

Back

The number of energy levels increases as you move down a group, leading to larger atomic sizes.

Front

Which element has a higher electronegativity than Arsenic (As)?

Back

Nitrogen (N) has a higher electronegativity than Arsenic (As).
