magnesium has a 2 valence electrons. because the third electron is not a valence electron, or in the outer shell, much more energy would be needed to remove it
First ionization energy of magnesium = 870/ kj/mol First ionization energy of phosphorous = 589 kj/mol So, magnesium has the larger ionization energy required to pull the first valance electron. Do you know why?
Magnesium is in group 2 of the Periodic table, and so has 2 electrons in its outermost energy level. Therefore, its outermost energy level is full once 2 electrons are removed, and so it has an ionisation number of 2
Chlorine is Cl, C is carbon. The first ionization energy of magnesium is less than that of chlorine.
ionization potential energy. but remember the atom must be neutral .
Successive ionization energies are the amount of energy required to remove an electron from an atom. Core electrons are closer to the nucleus and have higher ionization energies compared to valence electrons. By analyzing the ionization energy pattern, we can determine the number of core and valence electrons in an atom.

Mg + Ionization energy ----> Mg2+ + 2e
The magnesium ionization energy is the amount of energy required to remove one electron from a neutral magnesium atom to form a positively charged magnesium ion. The first ionization energy of magnesium is 737.7 kJ/mol, indicating the energy needed to remove the outermost electron.
because ionization energy increases from left to right on the periodic table. Ionization energy is the amount of energy needed to take an electron away from the atom, or the energy needed to ionize it. Since Sodium is more likely to give up an ion to complete the octet rule, it has a higher ionization energy.

Chlorine is Cl, C is carbon. The first ionization energy of magnesium is less than that of chlorine.
It is easier for a magnesium atom to lose electrons because it has two electrons in its outer shell, making it more stable to achieve a full outer shell with eight electrons through loss rather than gain.
The energy required to remove electrons from an atom is called ionization energy. It is the minimum energy needed to remove an electron from a neutral atom in the gaseous phase.

Beryllium will have the highest. Down a group ionization energy decreases.
low ionization energy
Ionization energy is the amount of energy needed to remove an electron from an atom. Elements with higher ionization energy are less likely to lose electrons and therefore are less reactive. Conversely, elements with lower ionization energy are more likely to lose electrons and are more reactive.
