it can form 3 bonds because 1 electron is in each of the 3 2p oribitals.
The electron configuration of nitrogen (atomic number 7) is 1s2 2s2 2px1 2py1 2pz1
so specifically the 2p oribital is :
2px1 2py1 2pz1
Answer:
128 neutrons
Explanation:
<em>How many neutrons are there in 8 molecules of </em>
<em>?</em>
Step 1: Calculate the number of neutrons in 1 atom of F.
The atomic number (z) of F is 9 and its mass number (A) is 19. We can calculate the number of neutrons using the following expression.
n⁰ = A - Z = 19 - 9 = 10
Step 2: Calculate the number of neutrons in 1 molecule of F₂.
1 molecule of F₂ contains 2 atoms of F. The number of neutrons in 1 molecule of F₂ is:
(8 n⁰/1 atom F) × (2 atom F/1 molecule F₂) = 16 n⁰/1 molecule F₂
Step 3: Calculate the number of neutrons in 8 molecules of F₂
8 molecule F₂ × 16 n⁰/1 molecule F₂ = 128 n⁰
