Group 16 (group 6A)
Group 16, the oxygen - sulfur group

The question is unclear, but from what I can understand the answer is the halogens.

first energy level contains only S shell that can accomadate 2 electrons where as 2nd energy level contains S shell and P shell as well which can accomadate 2 and 6(3X2) electrons respectively..so the answer is 8 for 2nd energy level. (or) No.of electrons in any main energy level = 2n2 Here n = orbit (or energy level) number In our question , n = 2 No.of electrons in 2nd energy level = 2(2)2 = 8
The second energy level contains eight valance electrons when it's full.

2. the number of electrons on the outermost level is always equal to the group number. Barium is group 2 therefore it's outermost energy level contains 2 electrons
The outer energy level is in the electron cloud surrounding the nucleus. Each ring that surrounds the nucleus is an energy level and contains a different number of electrons.
In atoms, whenever energy is supplied to it an electron or the required group of electrons traverses to higher level shells.

Carbon. Carbon is in the second period, so it has electrons in its second energy level, and it is in the fourth group in the second energy level, so it has 4 electrons.
first energy level contains only S shell that can accomadate 2 electrons where as 2nd energy level contains S shell and P shell as well which can accomadate 2 and 6(3X2) electrons respectively..so the answer is 8 for 2nd energy level. (or) No.of electrons in any main energy level = 2n2 Here n = orbit (or energy level) number In our question , n = 2 No.of electrons in 2nd energy level = 2(2)2 = 8
Atoms can fill their outermost energy level by either gaining electrons from other atoms or by sharing the outermost electrons with another atom.
The second energy level contains eight valance electrons when it's full.

Atoms of elements in Groups 13-18 have 10 fewer valence electrons than their groups numbers.However , helium atoms have only 2 valence electrons.
Oxygen atoms have 6 electrons in the highest occupied energy level. They are two 2s electrons and four 2p electrons. All elements in Group 16 have 6 valence electrons. For Groups 13-18, subtract 10 from the group number and that gives you the number of valence electrons (the electrons in the highest energy s and p orbitals). The Group 1 elements have one valence electron and the Group 2 elements have two valence electrons. The transition metals can vary in the number of valence electrons. You can't necessarily go by group number for them.
