Front

What is the atomic radius?

Back

The atomic radius is the distance from the nucleus of an atom to the outermost shell of electrons.

Front

Which element has the largest atomic radius?

Back

Francium (Fr) has the largest atomic radius among the elements.

Front

What are the most abundant elements on the periodic table?

Back

Most of the elements on the periodic table are metals.

Front

Define electronegativity.

Back

Electronegativity is how good an atom is at attracting shared electrons in a bond.

Front

What are alkali metals?

Back

Alkali metals are the group of elements in the first column of the periodic table, known for being highly reactive.

Front

What is the trend of atomic radius in the periodic table?

Back

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

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 metalloids?

Back

Metalloids are elements that have properties of both metals and nonmetals.
