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

How many neutrons are there in 8 molecules of <br><img src="https://tex.z-dn.net/?f=%20%5Cfrac%7B19%7D%7B9%7D%20f2" id="TexFormu
slega [8]

Answer:

128 neutrons

Explanation:

<em>How many neutrons are there in 8 molecules of </em>^{19} _9 F_2<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
