100 2s for the hundreds digit of 200-30010 2s for the tens digit of 220-23010 2s for the ones digit of 200-300________________________________120 '2s'
Exactly 16
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)
To determine how many 2s go into 18, you can divide 18 by 2. When you perform the calculation, 18 ÷ 2 equals 9. Therefore, there are nine 2s in 18.
To find out how many 2s are in 18, you can divide 18 by 2. When you do this, 18 divided by 2 equals 9. Therefore, there are nine 2s in 18.
Fluorine has 9 electrons, which occupy 2s and 2p orbitals. Therefore, there are a total of three orbitals in fluorine (one 2s orbital and two 2p orbitals).
22/2 - 2
9(2s-7)
2x2x2+2/2 = 9
There is only one 2s orbital in an atom.
Yes
s=4
if s is 2, 2s is 4. 3 squared is 9. 4 + 9 = 13. 13 / 5 = 2.6, which is not equal to 2.
