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 has the smallest atomic radius among Fr, F, N, and Ba?

Back

F (Fluorine) has the smallest atomic radius.

Front

Which element has the largest atomic radius among Fr, F, N, and Ba?

Back

Fr (Francium) has the largest atomic radius.

Front

Where are metalloids located on the periodic table?

Back

Metalloids are found along the stair-step line (diagonal) on the periodic table.

Front

What is ionization potential?

Back

Ionization potential 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.

Front

Which element has the highest ionization potential among Fr, F, N, and Ba?

Back

F (Fluorine) has the highest ionization potential.

Front

What is electronegativity?

Back

Electronegativity is a measure of the tendency of an atom to attract a bonding pair of electrons. It generally increases across a period and decreases down a group.

Front

Which element has the weakest electronegativity among Fr, F, N, and Ba?

Back

Fr (Francium) has the weakest electronegativity.

Front

How does atomic radius change across a period?

Back

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

Front

How does atomic radius change down a group?

Back

Atomic radius increases down a group due to the addition of electron shells.
