Your answer is correct. Quantum numbers,n and l can only take
positive values.
Where:
n = cannot be zero
l = any number from zero to n-1
<span>lm = any number between –l and +l
including zero</span>
<span>ms = either -1/2 or +1/2</span>
<span><span>
Looking at the choices, </span>(3, 2, 1, - 1/2 ) is the only choice that
satisfy the criteria.</span>

Answer is: there are 0,06525 moles of oxygen in 15 carat <span>benitoite</span>.
m(BaTi(SiO₃)₃) = 15 carat ÷ 5 carat/g = 3 g.
M(BaTi(SiO₃)₃) = Ar(Ba) + Ar(Ti) + 3Ar(Si) + 9Ar(O) · g/mol.
M(BaTi(SiO₃)₃) = 137,33 + 47,87 + 3 · 28,09 + 9 · 16 · g/mol.
M(BaTi(SiO₃)₃) = 413,5 g/mol.
n(BaTi(SiO₃)₃) = m(BaTi(SiO₃)₃) ÷ M(BaTi(SiO₃)₃).
n(BaTi(SiO₃)₃) = 3 g ÷ 413,5 g/mol.
n(BaTi(SiO₃)₃) = 0,00725 mol.
In one molecule of <span>benitoite there are nine oxygen atoms.
</span>n(O) = 9 · 0,00725 mol.
n(O) = 0,06525 mol.
1. rigid body assumption
2. CM motion to represent linear motion
3. dynamics discussions
It’s D, you can tell because there electrons w the highest energy it would be faster
