Question

Element X,Y,Z have atomic numbers 6,9,12. Which one :
a. Forms an anion
b. Forms a cation
c. State the type of bond between Y and Z and give its molecular formula.
(4 Points)

Answer 1

Explanation:

Given -

• X, Y, Z have atomic number 6,9,12

To Find -

1. Which one forms Anion
2. Which one forms Cation
3. State the type of bond between Y and Z and give its molecular formula.

As we know that :-

• Carbon (C) has atomic number 6. So, X is C
• Flourine (F) has atomic number 9. So, Y is F
• Magnesium (Mg) has atomic number 12. So, Z is Mg

Now,

1)

we know that Flourine is electron withdrawing element. So, Flourine forms Anion.

And

2)

Magnesium is electron donating element. So, Magnesium forms Cation.

3)

The bond between Y and Z is ionic Bond.

Molecular Formula ZY2 (MgF2).
