Component 4C Q1. If Magnesium has 12 protons in its nucleus, how many electrons does it have in orbits around it? Q2. What are the symbols for protons, neutrons, and electrons?​

Sagot :

Q1. Magnesium has 12 protons in its nucleus, which means it has an atomic number of 12. Therefore, it has 12 electrons in orbits around it, as the number of protons equals the number of electrons in a neutral atom.

Q2. The symbols for protons, neutrons, and electrons are:

  1. - Protons: p+ or p (positive charge)
  2. - Neutrons: n or n0 (no charge)
  3. - Electrons: e- or e (negative charge)

These symbols are commonly used in atomic notation to represent the composition of an atom.
