Question

NH3

1. What is the central atom?
2. How many atoms are bonded to the central atom?
3. How many lone pairs of electrons are on the central atom?
4. How many single bonds are there in this molecule?
5. How many multiple bonds (double and/or triple) are there in this molecule

Answer 1

Answer 2

The central atom has multiple atoms bonded to it. H can only make one bond (because it has one electron and two makes a full valence shell for it), so the central atom must be N.

Answer 3

Does that make sense so far?

Answer 4

Yeah it does

Answer 5

Could you help with the rest?

Answer 6

I can, but I would like for you to let me know what you think for 2.

Answer 7

3?

Answer 8

I concur. :)

Answer 9

Cool! How about 3?

Answer 10

Yay! is the answer 2?

Answer 11

It has 2 lone electrons, making 1 lone pair. Make sense?

Answer 12

Oh yeah I see that now

Answer 13

Awesome! How about 4?

Answer 14

I think it's 3 but I'm not sure

Answer 15

I agree. All 3 bonds with H are single bonds.

Answer 16

How about 5, then?

Answer 17

None?

Answer 18

Yup! :)

Answer 19

Thank you so much!

Answer 20

No worries
