4s 3p 3s 2p 1s This is probably one of the easiest chemistry problems in the book, you should probably look it up.
-3s*4p+-4s*3p -12sp+-12sp -24sp
Both the 3s and 4s sublevels are part of the s orbital, meaning they have spherical symmetry. They both contain electrons with similar energy levels, with the 4s sublevel having higher energy than the 3s sublevel.
1s 2s 3s 3p 4s 3d 4p
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
The subshells in the M shell are 3s, 3p, 3d, and 4s. In terms of increasing energy, the order would be 3s < 3p < 3d < 4s.
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
I phone 4s she said it on Instagram
Yes
