So... for the element of PHOSPHORUS, you already know that the atomic number tells you the number of electrons. That means there are 15 electrons in a Phosphorus atom. Looking at the picture, you can see there are two electrons in shell one, eight in shell two, and five in shell three.

Each orbital can hold 2 electrons (one of each spin), and a maximum of 7 f orbitals can have the same energy without violating Pauli's exclusion principle. The number of electrons in a 4f subshell can be anything between 0 (if it isn't filled) and 14 (2 electrons per orbital times 7 orbitals = 14 electrons).

In general, atoms are most stable, least reactive, when their outermost electron shell is full. Most of the elements important in biology need eight electrons in their outermost shell in order to be stable, and this rule of thumb is known as the octet rule.

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.

As there are 4 sub shells, those will be :- s,p,d,f giving a total of = 1+3+5+7= 16 orbitals and 1 electrons for each orbital with ms= -1/2 and +1/2 each.. Thus there will be 16 such electrons.

Thus, the number electrons present in n = 2 shell are 8 electrons.

The fourth shell has 4 subshells: the s subshell, which has 1 orbital with 2 electrons, the p subshell, which has 3 orbitals with 6 electrons, the d subshell, which has 5 orbitals with 10 electrons, and the f subshell, which has 7 orbitals with 14 electrons, for a total of 16 orbitals and 32 electrons.

That means there are 16 electrons in a sulfur atom. Looking at the picture, you can see there are two electrons in shell one, eight in shell two, and six in shell three. There are 6 electrons in the outer orbit of an atom of sulphur.

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.

So we get 2 + 5 = 7. 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.

The shell closest to the nucleus, 1n, can hold two electrons, while the next shell, 2n, can hold eight, and the third shell, 3n, can hold up to eighteen. ... This outermost shell is known as the valence shell, and the electrons found in it are called valence electrons.

So... for the element of ALUMINUM, you already know that the atomic number tells you the number of electrons. That means there are 13 electrons in a aluminum atom. Looking at the picture, you can see there are two electrons in shell one, eight in shell two, and three in shell three.
