Hydrogen need 1 more electron to fill outermost orbit. Then, H will act as anion.
valence electrons are the electrons in the outermost energy level
The valence electrons are the outermost electrons, i.e. those that reside in the outermost energy level.
Electrons in the outermost energy level are called valence electrons. The number of valence electrons on an atom largely determine its behavior and characteristics.
An oxygen atom has 6 electrons in its outermost energy level. In a water molecule, each hydrogen atom can share one electron with the oxygen atom, forming a covalent bond. This results in the oxygen atom having a total of 8 electrons in its outermost energy level.

Eight. Oxygen has 6 electrons and shares two more with the hydrogen atoms in covalent bonds
counting the shared electrons, 8.
In a water molecule, oxygen shares electrons with hydrogen atoms to form covalent bonds. Oxygen has 6 electrons in its outermost energy level, while hydrogen has 1 electron in its outermost energy level. Oxygen shares one electron with each of the two hydrogen atoms, forming two covalent bonds.
There are 6 electrons in the outermost energy level of an oxygen atom. In a water molecule, oxygen shares electrons with two hydrogen atoms to form covalent bonds, achieving a full outer shell with 8 electrons (octet rule). Oxygen shares one electron with each hydrogen atom to complete its outer shell.
