Periodic Trends

Front

What is atomic radius?

Back

The atomic radius is the distance from the nucleus of an atom to the outermost shell of electrons. It generally increases down a group and decreases across a period.

Front

Which element in Period 2 has the greatest atomic radius?

Back

Lithium (Li) has the greatest atomic radius in Period 2.

Front

What trend is observed in atomic radius as you move from left to right across a period?

Back

Atomic radius decreases as you move from left to right across a period due to increasing nuclear charge.

Front

Which element has the smallest atomic radius among Mg, Al, Si, and K?

Back

Silicon (Si) has the smallest atomic radius among these elements.

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 trend is observed in ionization energy as you move left to right across a period?

Back

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

Front

Which halogen has the smallest atomic radius?

Back

Fluorine (F) has the smallest atomic radius among the halogens.

Front

What is electronegativity?

Back

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

Front

Which has greater electronegativity: Nitrogen (N) or Carbon (C)?

Back

Nitrogen (N) has greater electronegativity than Carbon (C).

Front

What is the trend in electronegativity as you move down a group?

Back

Electronegativity generally decreases as you move down a group in the periodic table.
