What is the difference between mitosis and meiosis?

Meiosis has two rounds of genetic separation and cellular division while mitosis only has one of each. In meiosis homologous chromosomes separate leading to daughter cells that are not genetically identical. In mitosis the daughter cells are identical to the parent as well as to each other

Mitosis occurs in all eukaryotic cells and creates two identical cells from one mother cell.
Meiosis only occurs in the gamete/sex cells and creates four genetically different haploid cells from the mother cell.

The charge of an ion with 55 protons and 52 electrons is +3. the reason is because protons are positive, and there are three more than the amount of negative electrons.
