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.
sodium is a metal and has 11 electron with one electron being the valence electron. Its' electron configuration is 1s2, 2s2, 2p6, 3s1. Since sodium is a metal, to achieve noble gas configuration it must lose the 1 valence electron in the highest occupied energy level (3s1). When sodium loses the electron it comes a cation with a charge of 1+. The symbol for the sodium cation is now Na+
