What neutral element will have the electron configuration 1s22s22p63s23p1? Select one:
a. aluminum
b. boron
c. carbon
d. silicon

a. aluminum

Explanation:

Given electronic configuration:

       1s² 2s² 2p⁶ 3s² 3p¹  

The number of electrons can be determined from adding the powers or superscripts.

Since we are dealing with a neutral element, the number of electrons and protons are the same. So we can determine the atomic number which is the number of protons.

Number of electrons  = 2 + 2 + 6 + 2 + 1  = 13

The element with atomic number 13 is aluminum.

i think   the answer is c hope i'm right
