Answer:
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.
the answer is electrons.....
