Periodic Table and Periodic Trends

Front

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

Back

Atomic radius increases because you add more and more shells (energy levels).

Front

Which atom has the largest atomic radius: potassium, rubidium, francium, or cesium?

Back

Francium has the largest atomic radius.

Front

Which periodic group has the smallest atomic radius?

Back

Noble Gases have the smallest atomic radius.

Front

How does atomic radius generally change as you move down a group and across a period?

Back

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

Front

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

Back

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

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 electronegativity?

Back

Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons.

Front

Explain the trend of atomic radius across a period.

Back

Atomic radius decreases across a period from left to right due to increasing nuclear charge, which pulls electrons closer to the nucleus.

Front

What is the trend of electronegativity in the periodic table?

Back

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

Front

What are alkali metals?

Back

Alkali metals are the elements in Group 1 of the periodic table, known for being highly reactive and having one electron in their outermost shell.
