The ionization energies for successive removal of electrons from sodium are as follows: 496kJ, 4562kJ, 6912kJ, and 9544kJ. What does the jump in ionization energy indicate

Each calcium ion has a charge of +2, which can also be written as ca2+. if those ions move out of the neuron and no other ions are moving, the neuron would lose the positive charge associated with those ions and become more negatively charged.

Chromosomes can be used more than once atoms are all different
