The boron atom has only six electrons in its outer shell, leading to an electron deficiency. This molecule has 12 valence shell electrons; 3 each from the B atoms, and 1 each from the six H atoms.

This family has six electrons in the outermost shell. Selenium specifically has an electron configuration of 2-8-18-6. The six electrons in the outermost shell allow selenium to have a variety of valence numbers. Selenium compounds have been found that have valences of -2, 4, and 6.

Most atoms do not have eight electrons in their valence electron shell. Some atoms have only a few electrons in their outer shell, while some atoms lack only one or two electrons to have an octet.
294819
Noble gases have eight electrons in their outermost shell, except in the case of helium, which has two.
1054385
Rhenium Number of Valence Electrons Rhenium has 2 valence electrons in its outer shell.
1069320
It has only one electron in its valence shell. Valence electrons are the outermost electrons or electrons in the largest energy level. Hydrogen has only one electron, so that electron is a valence electron.
512933
So fluorine has 7 electrons in the outermost shell.
652304
The other inert gases including argon and xenon also have full outer shells with eight electrons. The inert gases have a valence number of 0.

If Hydrogen has 1 electron it can only have 1 outer shell (or orbital) as an electron cannot by split across shells. In general, the first shell can hold 2 electrons, the second can hold 8. Consequently, hydrogen only has 1 outer shell as it has less than 2 electrons so it does not need another shell.

Valence electron is the number of electrons present in the outermost orbit of an element . Oxygen has the atomic number 8. As the electronic configuration of oxygen 1s2 , 2s2, 2p4, it has 6 electrons in outermost orbit ( which is 2nd orbit) and no of electrons in this orbit is 6 ( 2+4).

Each shell can contain only a fixed number of electrons: The first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold up to 18 (2 + 6 + 10) and so on. The general formula is that the nth shell can in principle hold up to 2(n2) electrons.

Explanation: Since the atomic no. of carbon is 6 so its electronic configuration is 1s2 2s2 2p2 . Now the outermost orbit or shell or energy level is 2 or L and it has 2s2 and 2p2 so which gives the total of 4 electrons in all.

So how many electrons are in the outermost shell? You have six electrons here. So oxygen has six valence, valence electrons.
135404
Cobalt (Co) has an atomic number of 27, which means it has 27 electrons and protons. Shells hold up to two electrons in the first and eight electrons in the outer shells.

So fluorine has 7 electrons in the outermost shell. Basically, count the number of electrons in the orbitals with the highest principle quantum number, and that'll give the number of electrons in the outermost shell.
