The electron configuration for neon (atomic number = 10) is not 1s22s12p6. which of the following are reasons why? (mark all that apply.)

a)the 3s orbital should be part of the configuration.

b)the total number of electrons is incorrect.

c)the 2s orbital does not have enough electrons.

d) the 1s orbital does not have enough electrons.

The answer to your question is:  B and C.

Explanation:

Neon atomic number = 10

Electron configuration is not :   1s²2s¹2p⁶  .

This electron configuration is for fluor (9 electrons) because is we sum up the electrons ( 2 + 1 + 6) the result is 9.

A)The 3s orbital should be part of the configuration.  This is not the right reason.

B)The total number of electrons is incorrect.  This correct, the number of electrons is 9 instead of 10.

C)The 2s orbital does not have enough electrons.  This option is correct, 2s must have 2 electrons and it only has 1.

D) The 1s orbital does not have enough electrons. This option is incorrect, 1s orbital can have only 2 electrons.

the answer is 1260

you spend 7 hours in school for 1 school day with 5 school days in 1 school week with 36 school weeks in a school year.

7*5*36= 1260 it's all about multiplying
