Answer:
Because sodium is on the left side of the PT and phosporus is on the right side. And atomis radius decreases from left to right.
Explanation:
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
