If you are referring to the valence shell; the answer is one.
Hydrogen need 1 more electron to fill outermost orbit. Then, H will act as anion.

with an electron configuration that fills up to 2 electrons in their outermost energy level. This includes hydrogen and helium, which have one and two electrons in their outermost s orbital, respectively.
valence electrons are the electrons in the outermost energy level
1: The outermost ring of hydrogen is the s-level, which can contain only two electrons, and a hydrogen atom itself already has one of these 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.
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.
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.
Hydrogen need 1 more electron to fill outermost orbit. Then, H will act as anion.
No, hydrogen (H) has one electron in its outermost level.
Halogens have six valence electrons in the outermost energy level.
Carbon has four electrons in the outermost energy level, which is energy level two. It needs eight electrons to have this energy level filled.
Aluminum has 3 electrons in its outermost energy level.
A neutral atom of magnesium has 2 electrons in its outermost energy level. Magnesium has a total of 12 electrons, with 2 electrons in the first energy level and 8 electrons in the second energy level. The outermost energy level is the second energy level in the case of magnesium.
Outermost energy level is full if there are 8 electrons in the valence shell.
Atoms form chemical bonds to achieve a full outermost energy level by sharing, gaining, or losing electrons. Valence electrons are the electrons in the outermost energy level of an atom, and having a full outermost energy level makes the atom more stable. This stability is achieved when there are eight electrons in the outermost energy level, known as the octet rule.
