This is a chemical element. You can find the how many electron in a single atom by using a Periodic Table.
Titanium has the valence electron configuration of [Ar] 3d2 4s2. This means that Ti has 2 valence electrons, lying in the 4th s orbital. Note the relationship between the d-orbital and valence electrons is more complicated, but they are not regularly considered valence electrons.
Hydrogen doesn't really have a valence shell. It has one electron only.
BH3 has 3 valence electrons. Boron has 3 valence electrons and each hydrogen contributes 1 valence electron.
One. A hydrogen atom contains only one electron, and it is a valence electron.
Ammonia (NH3) has 8 valence electrons. Nitrogen contributes 5 valence electrons and each hydrogen contributes 1 valence electron.

Halogens each have 7 valence electrons.
Each potassium atom has one valence electron available for bonding.
Hydrogen doesn't really have a valence shell. It has one electron only.
BH3 has 3 valence electrons. Boron has 3 valence electrons and each hydrogen contributes 1 valence electron.
H2Se has six valence electrons. Each hydrogen contributes one valence electron, and selenium contributes four.
Alkali metals have one valence electron.
Arsenic should have 5 electron dots in its Lewis structure, one for each valence electron.
One. A hydrogen atom contains only one electron, and it is a valence electron.
one valence electrons
Ammonia (NH3) has 8 valence electrons. Nitrogen contributes 5 valence electrons and each hydrogen contributes 1 valence electron.
four. each electron can join with an electron from another atom to form a strong cavalent bond
