LI ; lithium is an example with 3 protons.
Lithium.
Lithium fills the bill. It has 3 protons in its nucleus.

Lithium.
The alkali metal. The alkali metal has less protons in the nucleus compared to the halogen in the same period and therefore exerts a relatively smaller attractive force on the outer-most shell electrons, enabling them to stray further away.
If you could see an alkali metal atom, it would have a nucleus containing protons and neutrons, and an electron cloud containing electrons. In the electron cloud, the highest energy level would contain only one electron.

It is calcium.

cerium
Protons are found in the nucleus of an atom, not around the nucleus as electrons are.
potassium
Sodium element contain 11 protons. It is a alkali metal.
In metals protons are free to move btw atoms throughout the piece of metal.
Lithium has the lowest number of protons of any metal: 3. Hydrogen an helium have fewer protons bu they are not metals.
The largest transition metal is copernicium with 112 protons.
