Which one resembles Nitrogen (N) after losing an electron:
Correct answer: A. Oxygen (O)
- A. Oxygen (O)
- B. Boron (B)
- C. Carbon (C)
- D. Sodium (Na)
Explanation
Oxygen has 8 electrons. After losing 1 electron, it will have 7 electrons which is the same as nitrogen. So, option A is correct. Boron has 5 electrons. After losing 1 electron, it will have 4 electrons which does not resemble nitrogen having 7 electrons. Hence, option B is incorrect. Carbon has 6 electrons. After losing 1 electron, it will have 5 electrons which does not resemble nitrogen having 7 electrons. Hence, option C is incorrect. Sodium has 11 electrons. After losing 1 electron, it will have 10 electrons which does not resemble nitrogen having 7 electrons. Hence, option D is also incorrect.

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.
