The median Social Security benefit was $16,295 for men and $11,999 for women in 2012, AARP found. Retirement savings. Just under a third (30 percent) of retirees receive income from either a traditional pension or take withdrawals from a retirement savings account such as a 401(k) or individual retirement account.
The Sodium atom. 1  The Na atom has an equal number of electrons and protons (11 e-and 11 p+). 2  This atom too is unstable because the outer valance shell of electrons has only one electron in it. 3  To be stable the outer shell of electrons should have eight electrons.
Charges of an elements ions can be worked out by figuring out if the element will GAIN or LOSE electrons when they react. So Sulfur with electron configuration of 2,8,6 in its outer valance shell will need to GAIN two electrons to get 8, and have a stable outer shell. This will mean there are 2 more electrons then protons and the overall ion will have a negative charge. So S2- (-2) is the answer.
