Front

What is atomic radius?

Back

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

Front

Which element has the smallest atomic radius: Li, O, C, F?

Back

F (Fluorine) has the smallest atomic radius among these elements.

Front

Which element has the largest atomic radius: Ca, Be, Ba, Sr?

Back

Ba (Barium) has the largest atomic radius among these elements.

Front

What do nonmetals tend to do with electrons?

Back

Nonmetals tend to gain electrons to become anions.

Front

How many valence electrons does Carbon have?

Back

Carbon has 4 valence electrons.

Front

Which element is classified as a metalloid?

Back

As (Arsenic) is classified as a metalloid.

Front

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

Back

The atomic radius increases as you move down a group in the periodic table.

Front

What is the trend of atomic radius across a period in the periodic table?

Back

The atomic radius decreases as you move from left to right across a period in the periodic table.

Front

Define cation.

Back

A cation is a positively charged ion that is formed when an atom loses one or more electrons.

Front

Define anion.

Back

An anion is a negatively charged ion that is formed when an atom gains one or more electrons.
