Why does electronegativity increase as you go across a period? It is no wonder the electron pair gets dragged so far towards the chlorine that ions are formed.

Are the daughter cells identical in meiosis?
Are the daughter cells identical in meiosis? Like mitosis, meiosis is a form of eukaryotic cell division. Mitosis creates two identical daughter cells that each contain the same number of chromosomes as their parent cell. In contrast, meiosis gives rise to four unique daughter cells, each of which has half the number of chromosomes as […]
