Question

If an atom of nitrogen binds with three hydrogen atoms to form a molecule of ammonia, how many lone pairs of electrons does nitrogen have?

Answer 1

@Abmon98

Answer 2

@Somy

Answer 3

i thinks its 4

Answer 4

look at the electronic configuration of nitrogen which is 2,5

Answer 5

NH3

Answer 6

so its 3

Answer 7

no no

Answer 8

look how many electrons are there in N's last shell?

Answer 9

@pinal145

Answer 10

only the outermost shell of the element is involved in bonding

Answer 11

i dont know what you mean by the last shell

Answer 12

so its 5

Answer 13

yes
and how many are involved in bonding with H atoms?

Answer 14

2

Answer 15

the shell which contains 2 electrons is stable (not involved in bonding) only the shell which carries 5 electrons are involved. Ammonia, Nitrogen Bonded to 3 other hydrogens so were left with 2 electrons(not involved in bonding)

Answer 16

so answer is 1 lone pair
