1, because it has an atomic number of one, meaning it has 1 proton & 1 electron. It takes 2 electrons to fill the first electron shell, but hydrogen only has 1. So it remains at the 1st shell.
Hydrogen doesn't really have a valence shell. It has one electron only.
There are 6 electrons in the outer shell of CH2O. Carbon has 4 outer electrons, hydrogen has 1 each, and oxygen has 6.
The innermost shell of every atom except hydrogen consists of 2 electrons.
Hydrogen only has one electron, which fills its only electron shell (the first shell).
1st shell: 2 electrons, 2nd shell: 8 electrons, 3rd shell: 8 electrons, 4th shell: 4 electrons, 5th shell: 0 electrons, 6th shell: 0 electrons.
there are 2 electrons in the inner shell of a hydrogen atom.
Hydrogen doesn't really have a valence shell. It has one electron only.
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.

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.
Only one electron for hydrogen.
Carbon has 2 electrons in it's first electron shell. All elements except hydrogen do.
two
The innermost shell of every atom except hydrogen consists of 2 electrons.
Hydrogen only has one electron, which fills its only electron shell (the first shell).
Hydrogen has only one electron and occupies the first shell (1s). The second shell (2s and 2p) can hold a maximum of eight electrons. Therefore, hydrogen would require seven additional electrons to fill up the second shell completely.
