Question

How many valence electrons are in an atom with the electron configuration in example A?

A. 22
B. 2
C. 4
D. 6

the example will be in the pic

Answer 1

I think 22

Answer 2

ok, why though?

Answer 3

i added together all of the little exponent things. i could be wrong tho

Answer 4

but is that how you calculate valence electrons?

Answer 5

I dont know for sure. Thats why I said I could be wrong

Answer 6

*died*

Answer 7

count the number on top 2+2+6+2+6+2+2 = 22

Answer 8

2+8+8+4=22

Answer 9

are you sure?

Answer 10

yup

Answer 11

Total=22
valence electrons =4
electrons in the outermost shell.
i may be wrong.

Answer 12

yea see? i said 22

Answer 13

so is it 4 or 22? 🥲💀

Answer 14

Disagree with 22. It is only looking for valence electrons (electrons in the outermost shell), which is n = 4, and therefore you only want the electrons in 4s2 4p2
