-3s*4p+-4s*3p -12sp+-12sp -24sp
4s 3p 3s 2p 1s This is probably one of the easiest chemistry problems in the book, you should probably look it up.
They are both s level orbitals; they can carry two electrons and are spherical in shape. The only difference is that the 4s level is larger than the 3s, and the 3s level will fill first.
4s-5-3s =s-5 The s and 5 can not subtract because they aren't like terms. Like terms have the same variable.
Bring all the unknown values to one side and the known values to the other 7s - 12 = 3s - 4 Subtract 3s from both sides 7s - 3s - 12 = 4 4s - 12 = 4 Add 12 to both sides 4s = 4 + 12 4s = 16 Divide both sides by 4 s = 4
2t-4s
-6r - s
Let F = father's age Let S = son's age F = 3S F - 5 = 4(S-5) F - 5 = 4S -20 F = 4S - 15 F = 3S 3S = 4S-15 S = 15, age of son
1s 2s 3s 3p 4s 3d 4p
I phone 4s she said it on Instagram
3s will have the lowest energy among the options given
Yes
