This is a chemical element. You can find the how many electron in a single atom by using a Periodic Table.
There are 3 shells total in the atom of Chlorine. The first shell has 2 electrons because the first shell of any atom can only hold up to a maximum of 2 electrons. The second shell holds 8 electrons because the second shell of any atom can only hold 8 electrons maximum. The third shell holds 7 electrons in the Chlorine atom, but the third shell of any atom can hold up to 18 electrons as a maximum.
firstly the protons are in the nucleus of an atom. there are 16 protons there. the number of electrons is the same as the number of protons. the electron arrangement is as follows: first shell-2 electrons second shell - 8 electrons third shell - 6 electrons this can also be written as 2,8,6
In case of sulphur there are 3 energy levels.The first one contains 2 electrons,the second one contains 8 electrons and the third one contains 6 electrons.So the atomic number is 16 and valence electron/number of electrons in the outermost shell is 6.
It has 5 electrons in its outermost shell.
To determine how many electrons are in each shell (or energy level), you simply take two times the number of the shell or level squared. Two electrons are allowed in the first shell, eight in the second shell, eighteen in the third shell, thirty two in the fourth shell, fifty in the fifth shell, seventy two in the fifth shell, and so on.
In the first shell there are two electrons and in the second shell there are six electrons, but only the electrons in the second (outer) shell are valence electrons.
8 electrons
14 electrons. 2 electrons in the first shell, 8 electrons in second shell, and 4 electrons in the valence shell.
4 electrons
First Shell always has 2 electrons. Second shell onwards can have up to a maximum of 8 electrons.
it takes 8 electrons for the second shell to be considered full
Eight electrons fit in the second shell.
There 8 electrons in the second shell.
4
Eight electrons in the 2nd shell of Br- This is also the number of electrons in the 2nd shell of I-, Cl- and even F- !
eight
The first shell can hold a maximum of 2 electrons, the second shell can hold up to 8 while the third shell can also hold a maximum of 8.
