Question

An element ‘A’ has the electronic configuration [Ne] 3s2and another element ‘B’ has the electronic configuration [Ne] 3s23p5. What type of bond may be formed between these two elements if they chemically combine? Write the formula and Lewis structure of the product.

Answer 1

Explanation:

Given -

• Element A has electronic configuration [Ne] 3s²
• Element B has electronic configuration [Ne] 3s² 3p^5

To Find -

1. Which type of bond may be formed between these two elements if they chemically combine.
2. write the formula.
3. Draw Lewis structure of the product.

Element A has electronic configuration [Ne] 3s² .

It means,

Its atomic number is 12.

Now, It is cleared that Element A is Magnesium (Mg).

And

Element B has Electronic configuration

[Ne] 3s² 3p^5

It means,

Its atomic number is 17

Now, It is cleared that Element B is Chlorine (Cl)

Now,

1)

This compound will form Ionic bond.

2)

Formula of the compound formed is MgCl2

3)
