If an element contains 8 electrons how many electrons will be placed in the 2nd valence shell? 6 2 8 5 11

The correct option is 6

Explanation:

The first shell of an atom can contain a maximum of two electrons and must be completely filled (with the two electrons) before the next electron shell is considered for filling. The second electron shell can contain a maximum of eight electrons.

If an element has 8 electrons, 2 of this electrons will occupy/completely fill the first electron shell, while the second shell will only contain the remaining 6 electrons.

NOTE: A neutral atom of an element with 8 electrons is oxygen.

the atomic mass is the bottom number on the element.
