lose 3 electrons from its second shell
Valence electrons of any atom are located in the outermost shell that atom carries electrons. For example a carbon atom has 6 electrons: 2e in its first shell (which is full) and 4e (valence electrons) in second shell--there are no electrons farther than second shell for carbon.
2 electrons in the first shell then 3 electrons in the second shell
the first shell: 2 electrons The second shell: 8 electrons The third shell: 18 electrons The fourth shell: 3 electrons
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.
Oxygen. Two of the electrons are in the first shell. The other six of them are in the second shell.
First Shell always has 2 electrons. Second shell onwards can have up to a maximum of 8 electrons.
valence electrons or the electrons on the outer most shell.
The second shell can hold eight electrons.
Neon atom number 10: first shell (K) : 2 electrons second shell (L): 8 electrons all shells being filled up completely
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.
3. 2 in the first shell, 1 in the second
