🤓 Based on our data, we think this question is relevant for Professor Dixon's class at UCF.

Solution: a) Give the ground-state electron configuration for silicon (Si).b) Give the actual ground-state electron configuration for copper (Cu).

Problem

a) Give the ground-state electron configuration for silicon (Si).

b) Give the actual ground-state electron configuration for copper (Cu).

Solution
  • Silicon has atomic number of 14. Atomic number is equal to the # of proton and at ground state, it is also equal to the # of electron

  • Si at ground state has 14 electrons

  • Using the periodic table as guide, Si will appear as:
