Question

What is the electron configuration of the element with 27 protons?

Answer 1

Can you identify the element with 27 protons by name?

Answer 2

I'll start you off
1s2 2s2 2p6 3s2 3p6

the next 2 suborbitals are 4s and 3d

Answer 3

its a member of the transitional group of elements

Answer 4

Cobalt @JoannaBlackwelder

Answer 5

Great! :-) From here we know that cobalt has 27 electrons (to balance out the 27 protons).

Answer 6

And we need to add them in the order found here: http://chemwiki.ucdavis.edu/Inorganic_Chemistry/Electronic_Configurations

Answer 7

Each orbital hold 2 electrons. s subshells have 1 orbital, p subshells have 3 orbitals, and d subshells have 5 orbitals.

Answer 8

Do you see how @cwrw238 came up with the electron configuration up to argon?

Answer 9

I guess she knows. But she doesn't know the sequence.
Its
1s,2s,2p,3s,3p,4s,3d,4p,......
This way
now @JoannaBlackwelder is right about the orbitals.
so s can contain 2 electrons,
p, 6 electrons,
d, 10 electrons
and f 14 electrons.

Answer 10

cwrw238 knows all right She's a chemistry major.

Answer 11

wow @welshfella !

Answer 12

yea she's my niece . She's also just finished a degree course in Math.

Answer 13

Thanks to this website that I am having a conversation with you guys.!
Awesome!
