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

How does calcium's first ionization energy compare to the first ionization energy of magnesium and potassium?

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?


What is the chemical equation for magnesium using 2 electrons to form magnesium ion?

Mg + Ionization energy ----> Mg2+ + 2e


What is magnesium ionization energy?

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.


Why is the ionistaion energy of magnesium higher than that of sodium?

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.


Why does magnesium have an ionization number of 2?

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


Which one has the lowest ionization energy magnesium (Mg) chlorine (C?

Chlorine is Cl, C is carbon. The first ionization energy of magnesium is less than that of chlorine.


Is it going to be easier for a magnesium atom to gain or lose electrons?

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?

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.


What is the energy needed to remove electrons from an atom called?

ionization potential energy. but remember the atom must be neutral .


What elements has the highest first ionization energy out of strontium magnesium beryllium calcium?

Beryllium will have the highest. Down a group ionization energy decreases.


Do the elements form anion have high or loe ionization energy?

low ionization energy


How does ionization energy impact the reactivity of an element?

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.
