Hydrogen doesn't really have a valence shell. It has one electron only.
Nitrogen has 5 electrons in its outer shell, so there are 3 electron pairs in the outer shell of nitrogen.
It needs only 1 more electron since it already has 7 valence electrons.
there are 36 electrons in a valence shell. -cmoney
5s1, so one valence electron in the 5th shell
it shares four.
Arsenic (As) has five valence electrons in its outer shell, which is the third energy level. It typically has one lone pair and three bonding pairs when forming compounds. Therefore, there are a total of four electron pairs in the outer shell of arsenic.
Hydrogen doesn't really have a valence shell. It has one electron only.
Nitrogen has 5 electrons in its outer shell, so there are 3 electron pairs in the outer shell of nitrogen.
There is one electron in sodium's valance shell.
1 valence electron
the valence shell is the outermost shell of an atom that has free electrons for taking part in chemical reactions... the valence shell of sodium has one free electron
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
It needs only 1 more electron since it already has 7 valence electrons.
Sodium is in the third group in the periodic table. It meens that sodium has three shell. First shell - 2 electrons, second shell - 8 electrons, third shell (outer energy level) - 1 electron.
