Valency of hydrogen

Hydrogen and all the other atoms in group one of the periodic table (including lithium, sodium and potassium) have a valence of one. Group two atoms (including beryllium, magnesium, calcium, strontium and barium) have a valence of two.

Atoms with more than two valence electrons can have more than one valence, but their maximum valence is usually the same number as their valence electrons.

Groups three through 12 (the transition elements, including most metals) have varying valences between one and seven.

Group 13 atoms (including boron and aluminum) have a maximum valence of three.

How many valence electrons does hydrogen need to be stable

Group 14 atoms (including carbon, silicon and germanium) have a maximum valence of four. Group 15 atoms (including nitrogen, phosphorus and arsenic) have a maximum valence of five. Group 16 atoms (including oxygen, sulfur and selenium) have a maximum valence of six.

Group 17 atoms (including fluorine, chlorine and bromine) have a maximum valence of seven. Group 18 atoms, the noble gases (including neon and argon), have eight valence electrons, but because they almost n
