Does Cerium Have Valence Electrons?

It is a ductile metal with a hardness similar to that of silver. Its 58 electrons are arranged in the configuration [Xe]4f¹5d¹6s², of which the four outer electrons are valence electrons.

What elements has 4 valence electrons?

Carbon has four valence electrons and here a valence of four.

How do we find valence electrons?

For neutral atoms, the number of valence electrons is equal to the atom's main group number. The main group number for an element can be found from its column on the periodic table. For example, carbon is in group 4 and has 4 valence electrons. Oxygen is in group 6 and has 6 valence electrons.
