Additional energy is required to move second and successive electrons from an ion. Which element could have the following series of ionization energies (IE)? IE1 = 738 kJ/mol; IE2 = 1450 kJ/mol; IE3 = 7730 kJ/mol; IE4 = 10545 kJ/mol; IE6 = 17995 kJ/mol

Magnesium (Mg)

Explanation:

Ionization energy is the energy required to remove an electron from a gaseous atom or ion.

The first or initial ionization energy of an atomis the energy required to remove one mole of electrons from one mole of isolated gaseous atoms or ions.

The second ionization energy is the amount of energy required to remove the second valence electron.

under a microscope, cancer cells may look very different from normal cells. they often have different sizes and some may be larger than normal while others are smaller. cancer cells are often abnormally shaped and the control centre of the cell (the nucleus) may have an abnormal appearance.
