Answer: There are 4 bonding electrons and 18 non-bonding electrons.
Explanation: To determine the number of bonding and non-bonding electrons, we will use lewis dot structure for the molecule 
Lewis dot structure is the structure in which the valence electrons around an atom is shown in a molecule. It also tells us about the number of bonds present between the two neighboring atoms.
Valence electrons of Fluorine = 7
Valence electrons of Xenon = 8
In 
Total number of valence electrons = [(1 × 8) + (2 × 7)] = 22 electrons
From, the structure attached below, the number of bonds present = 2. Hence, the bonding electrons will be = 4 electrons
- Number of non - bonding electrons = Total valence electrons - Number of bonding electrons
Number of non-bonding electrons = 22 - 4 = 18
Option C: the electrons are embedded in a positive sphere.
As we know that was a wrong model and nowadays the electrons are considered to be around the nucleus, in regions called orbitals.
The atomic mass is measured in "atomic mass units" (amu). One mole of an element weighs the same atomic mass number, but in grams.
For example, carbon, C, has an atomic mass of 12.011 amu. One mole of carbon has a mass of 12.011 grams.
