All of the F's sublevels, including the 5F contains 7 orbitals. Then, each orbital should contain 2 electrons. From the given above, the number of electrons in the sublevel is calculated through,
n = (7 orbitals) x (2 electrons / orbital) = 14 electrons
Thus, the 5F sublevel contains 14 electrons.
The Na and CO3^2- ions. They are the same on both sides of the equation, so you ignore them and cancel them out.
Answer 6
Explanation: That means a carbon atom has 6 protons, 6 neutrons, and 6 electrons.
To solve this problem you would add 3/4 to 7 1/3.
3 22
4 3
9 88
12 12
97
12
8 1/12
The final answer would be 8 and 1/12
