Question

Can any one tell me same for ALCL3 I need it urgently plzzz ​

Answer 1

Lets Form bonds

Al=2,8,3

Lets Write actual configuration or modern

$\\ \sf\longmapsto 1s^22s^22p^63s^3$

• It has valency +3

Cl:-2,8,7

Let's write configuration

$\\ \sf\longmapsto 1s^22s^22p^63s^23p^5$

• It has valency -1

Now Criss cross valency (Refer to attachment)

We get

$\\ \sf\longmapsto AlCl_3$
