Question

The number of vacant orbitals in the valance shell of an atom of element with Z= 14 is
A 1
B 7
C 5
D 6

Answer 1

@nincompoop @Preetha

Answer 2

Z=14
2,8,4 --->14

Answer 3

and outermost shell can contain atmost 18 electrons, yes ?
but it only has 4

Answer 4

so, 14 vacant orbitals ?
that seems wrong :P

Answer 5

14 is number of electrons...any ideas how to find vacant orbitals ?

Answer 6

Confused
What is vacant orbital means . I. Know element is silicon

Answer 7

@sarah786 wut answer do u think is correct?

Answer 8

I can't figure it out . 1s2 2s2 2p6 3s2 3p2

Answer 9

ok so out of

K 1s 2 2

L 2s 2 2 + 6 = 8
2p 6
M 3s 2 2 + 6 + 10= 18
3p 6
3d

these 6 orbitals

3 are occupied

Answer 10

And orbitals are sub shell s

Answer 11

K and L will be completely occupied

for M, out of 4, 2 goes in 3s

2 goes in 3p

and only 3d is vacant orbital!

Answer 12

Its 5 got it yay thank you so much hartnncand ya said ya dunno even c of chemistry :)

Answer 13

5 are occupied orbitals

1 is vacant!

Answer 14

everything i posted above, i have just googled it, learned it

Answer 15

D is a single orbital ? Then what dxy dyz dzx called ?

Answer 16

lol, thats deep....i don't know that.. :P

Answer 17

XD

Answer 18

from wiki
"The simple names s orbital, p orbital, d orbital and f orbital refer to orbitals with angular momentum quantum number ℓ = 0, 1, 2 and 3 respectively. "

Answer 19

OK got it its 1 because s p d f are orbitals thank you so much :)

Answer 20

finally we got it ! :)
welcome ^_^
