How many electrons would be in the second shell of an
Atom with the atomic number 7?

5

Explanation:

Atomic number of atom = 7

 The atomic number is the number of protons in an atom. For most neutral compounds, the atomic number is the same as number of electrons. This specie has 7 electrons;

   Shell configuration;

    Number of electrons = 7

  Configuration = 2, 5

Number electrons in the second shell  = 5

practical process described pest part of scientific investigation.

because practical knowledge is powerful then therotical knowledge.

catya your not at all which answer i've seen you do this on another question!
