It is called hydride, or H-.
there are 2 electrons in the inner shell of a hydrogen atom.
The total number of electrons in a hydrogen cyanide (HCN) molecule is 10. Hydrogen contributes 2 electrons, carbon contributes 4 electrons, and nitrogen contributes 5 electrons. Combined, this totals 11 electrons.
It depends on what kind of ion:If it's a cation (H+) then there is 1 proton and 0 electrons, so zero.If it's an anion (H-) then there is 1 proton and 2 electrons, so 2 (and that shell is full).
The hydrogen ion H+ is without electrons.
The first orbital of hydrogen, which is the 1s orbital, can hold a maximum of 2 electrons.

No. Hydrogen has only one
2
An oxygen atom has 6 electrons in its outermost energy level. When it shares electrons with two hydrogen atoms to form a water molecule, oxygen will share 2 of its electrons with each hydrogen atom, allowing each hydrogen to complete its outermost energy level with 2 electrons. This results in oxygen having a full outermost energy level with 8 electrons.
In a hydrogen atom, the outermost level has a maximum capacity of 2 electrons. If there are no electrons in the outermost level, it means there are 2 unoccupied spaces available for electrons to occupy.

There would be two electrons. The electronic configuration would be just 1s2 and this is termed the duplet configuration.
Each hydrogen atom has one electron on its outer shell. The first electronic shell of any element can only hold 2 electrons, this means that each hydrogen atom needs one electron. 2 hydrogen atoms 'share' their electrons with each other, this can be shown on a dot and cross diagram. Each hydrogen now has 2 electrons on their outer shell and they have become stable. ;)
A molecule of of H2O has 10 electrons: two from the hydrogen and 8 from the oxygen.
The hydrogen ion H+ is without electrons.
Hydrogen is an atom that does not need 8 electrons in its outer energy level to be stable. Hydrogen only needs 2 electrons to fill its outer energy level.
