The hydronium ion has NO(zero) electrons in its outer structure It can be thought of as a 'single proton'.
However, it usually combines/attached to another molecule, such as water making the hydronium ion ' H3O^(+) '. or an ammonia molecule making the ammonium ion ' NH4^(+) ' .
This is because these two molecule have lone pairs of electrons in their outer energy shells to which the 'proton' can attach.
There are 6 electrons in the outer shell of CH2O. Carbon has 4 outer electrons, hydrogen has 1 each, and oxygen has 6.
Hydrogen has one electron. Its outer shell the first energy level has just one orbital, 1s which could hold a maximum of 2 electrons, so hydrogen only partially fills the level.
Hydrogen only has one electron, which fills its only electron shell (the first shell).
Nitrogen has five electrons in its outer shell and bromine has seven in its outer shell.
Boron has three electrons in its outer shell
Only one electron for hydrogen.
There are 6 electrons in the outer shell of CH2O. Carbon has 4 outer electrons, hydrogen has 1 each, and oxygen has 6.
Two electrons will fill a hydrogen's outer, or valence, shell.

Hydrogen has 1 electron in its outer shell, and in fact only 1 electron in total.
Hydrogen has one electron. Its outer shell the first energy level has just one orbital, 1s which could hold a maximum of 2 electrons, so hydrogen only partially fills the level.
Hydrogen has one electron in its outer shell and typically needs one more electron to achieve a full outer shell, which would complete its valence shell with two electrons (like helium). Therefore, hydrogen would need one additional electron to have a full outer shell.
Each element has shells of electrons and they are limited to how many can be shared in the outer shell. This lets us know what and how many atoms can combine with it. Hydrogen has the need for one electron in its outer shell. Oxygen has the need for two more electrons in its outer shell. Therefore, 2 hydrogen atoms can combine with oxygen.
Hydrogen only has one electron, which fills its only electron shell (the first shell).
Nitrogen has five electrons in its outer shell and bromine has seven in its outer shell.
Boron has three electrons in its outer shell
Vanadium has on the outer shell two electrons.
