Which of these is true for Na+1 and Mg+2:
Correct answer: C. Both have 10 electrons
- A. Na+1 is smaller in size as compared to Mg+2
- B. Sodium has lost its valence shell while Mg hasn't
- C. Both have 10 electrons
- D. Both have 11 and 12 electrons respectively
Explanation
Na+ = 11 - 1 = 10 Mg+2 = 12 - 2 = 10 Hence, both have 10 electrons.

About Atomic Structure
Atomic structure covers the discovery of the proton, Planck's quantum theory, hydrogen emission spectra and the evidence for quantized energy levels. You will use quantum numbers to describe orbitals, distinguish s, p, d and f orbital shapes, and write electronic configurations, including the correct order of electron filling.
