Based on the octet rule, bromine requires exactly one electron to fill its valence shell.
Bromine can gain a stable outer electron shell by accepting one electron to fill its 4p orbital, achieving a full valence shell of eight electrons. This allows it to have the electron configuration of a noble gas, like argon, and become a stable ion.
Antimony needs 3 electrons to fill its valence shell, which has 5 electron slots. Antimony typically forms compounds by gaining 3 electrons to achieve a stable octet configuration.
Phosphorus has 5 electrons in its valence shell. To fill the valence shell, it needs to gain 3 more electrons, bringing the total to 8 electrons, which is a stable configuration known as the octet rule.
The atomic number for hydrogen (H) is 1 in the Periodic Table of Elements and it has that number of electrons (Valence & otherwise). Hence H2O for water since Oxygen O needs 2 electrons added to its valence electrons to make the stable compound WATER.
The outermost energy level of an atom is known as the valence shell. In general, the valence shell can hold up to 8 electrons. However, the number of electrons that actually fill the valence shell can vary depending on the element and its position in the periodic table.
Carbon has four valence electrons, so it will need four more electrons to fill its outer shell.
Two electrons will fill a hydrogen's outer, or valence, shell.
* Ground state electron configuration:[Ar].3d10.4s2.4p6 so...4s and 4p
Carbon has four valence electrons, so it will need four more electrons to fill its outer shell.
Hydrogen has one electron and needs one more. Helium has two electrons and has filled shell. Carbon needs four more electrons to fill the valence shell Oxygen needs two more electrons to fill the valence shell

Beryllium will lose 2 electrons to satisfy the octet rule (to fill its outer shell).
Carbon needs 4 electrons to fill up its outer shell. It has 4 valence electrons and can achieve a full octet by gaining 4 more electrons.
It will lose 2 electrons.
When these elements have five electrons on the outermost shell of electrons.
