How does calcium's first ionization energy compare to the first ionization energy of magnesium and potassium?
Wiki User
∙ 8y ago
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?

∙ 13y agoNo. Calcium has a lower first ionization energy than Magnesium. They are in the same group on the Periodic Table, and in general the ionization energies decrease down a group. Magnesium is above Calcium in Group 2 of the Periodic Table, therefore Magnesium has a higher first ionization energy. That's because the first ionization energy is the energy required to lose one electron (which will always be an outermost electron). As you move down the periodic table, successive layers of electrons are added. The farther the outermost electrons get from the nucleus of an atom, the easier it gets to remove an electron. So, Magnesium is a smaller atom than Calcium, so the attraction between the nucleus of the Mg atom and its outermost electrons is relatively strong in comparison to Calcium atoms. The Ca atoms are larger because they have another layer of electrons and the attraction between the Ca nucleus and its outermost electrons is relatively weaker when compared to Mg.

Calcium gets 2 electrons removed whenever it bonds with a non-metal in an ionic bond, which follows the octet rule. So, it will lose those 2 electrons fairly easily. Chlorine, on the other had, must gain 1 electron in order to observe the octet rule. Therefore, it doesn't need to lose any electrons. Chlorine has the higher ionization energy.

How does the size of a magnesium ion with a 2 positive charge compare with that of a sodium ion with a single positive charge?
A magnesium ion will be smaller because there will be a greater Zeff on the electrons in the magnesium ion due to a greater number of protons in the nucleus.
How does the number of atoms in one mole of beryllium compare with the number of atoms in one mole of magnesium?
There are the same number of atoms in one mole of beryllium as there are in one mole of magnesium :)
How does copper compare to magnesium when you burn the copper?
Magnesium burns very easily indeed and is self sustaining once it is burning. Copper is extremely difficult to burn and requires very high temperatures.
Compare and contrast the two upper layers of the mantle?
The inner mantle comprises of silicon and magnesium sulphides and oxides while the outer mantle consists of tough liquid rock with iron and magnesium silicates.
How does the ionization energy of Ne compare to that of Se?
Neon is a much smaller atom than selenium because neon has fewer occupied energy levels so it has a considerably smaller atomic radius. For that reason, it will be more difficult to remove an electron from Ne than Se, so Ne has the greater ionization energy.
What is the significance of isolated gaseous atom while defining the ionization enthalpy?
isolated gaseous atoms ionization enthalpy is taken as reference value and its required to compare this values to various ions of this elements and to compare this values with various elements
Displacement reaction of sodium and magnesium?
Compare the reactions with water of the elements sodium and magnesium
How does Magnesium's atomic radius compare to aluminum?
Magnesium's atomic radius is smaller than Calcium's.
Compare the chemicals or minerals found in tap water and new water?
In our tap water, you can find minerals such as: sodium, potassium, manganese , iron, copper and calcium. The chemicals are typically just chlorine and fluorine. :)
How does the density of magnesium compare with that of water?
It is greater than water. It sinks.
Why is potassium chloride good conductor of electricity?
potassium atom has a bigger atomic radius and its valence electron located at 4th shell with more shielding effect so lower ionization energy required so more free electrons so better conductivity for electricity

Infer Magnesium and sodium atoms are about the same size How does the size of a magnesium ion with a 2 charge compare with that of a sodium ion with a single charge?
The sodium ion will be larger. Because magnesium has one more proton than sodium, its nuclei pull harder on the electrons, reducing the ion's radius. This means that the magnesium ion is smaller.
Compare the degree of ionization of hcl and ch3cooh?
HCL is completely (or nearly 100%) ionized because it is a strong acid whereas the CH3COOH is partially ionized as it is a weak acid.
