The H-atom has fourth energy level with n=4.
This
energy level can have values of orbital angular momentum l = 0, 1, 2, 3
Now each l can also have magnetic momentum ml from – l to l.
Therefore,
l = 0
<span>ml = 0 </span>
l = 1
ml = -1, 0, 1
l = 2
ml = -2, -1, 0, 1, 2
l = 3
ml = -3, -2, -1, 0, 1, 2, 3
Now adding up all the number of ml’s will give us the total
number of orbitals:
orbitals = 1 + 3 + 5 + 7
orbitals = 16
Alternatively, we can simply use the formula:
<span>orbitals = n^2 = 4^2 = 16</span>
Answer:
Fluorine
Explanation:
Data obtained from the question include:
The isotope of fluorine has:
Proton = 9
Neutron = 10
The atomic number is the proton number of the atom.
Therefore, the atomic number = 9
Mass number = proton + Neutron
Mass number = 9 + 10
Mass number = 19
Now comparing the above with the fluorine atom in the periodic table. We'll discover that the isotope is actually fluorine atom.
Therefore, the name of the isotope is fluorine
