There is only one 2s orbital in an atom.
An electron is transferred from the 2s orbital of lithium to form a Li ion. This results in the formation of a Li+ ion with a filled 1s and empty 2s orbital.
hydrogen
Lithium
You can tell the difference between a 2s sub-shell and 2p sub-shell from their energy levels, because a 2p sub-shell is a higher energy level than a 2s sub-shell.

The name used for the US state and river is spelled Mississippi. (2s, 2s, 2p)
s+s2+s+32s2=2s+s2+32s2=2s+33s2I am pretty sure that that is the correct answer.
You need to make your question clearer.
4s2 - 9 can be expressed by using the identity: a2 - b2 = (a-b)(a+b) Therefore, 4s2 - 9 = (2s)2 - 32 = (2s-3)(2s+3)
The equivalent is 7s+2s = 9s
22x2x2 is 88
They were subsidiary to Media and took it over, then used this combined power to create their empire.
2s - 12 + 2s = 4s - 124s - 12 = 4s - 124s = 4ss = s==========this is an identity and any number can be s
2s + 16 = 4s - 6 Subtract 2s from both sides: 16 = 2s - 6 Add 6 to both sides: 22 = 2s divide both sides by 2: s = 11
Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "times", "divided by", "equals". I believe there is symbol missing between "... power of -5" and "b to the power ...".
