Best Answer

The Na+ will have a larger size (atomic radius) while Mg2+ will have relatively smaller size. Both elements have lost their valence (outermost) electrons and achieve a stable octet state as ions. what makes a difference is the effective nuclear charge. because Mg has a higher nuclear charge, the valence electrons are pulled more towards the nucleus thereby reducing the atomic radius.

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.


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.

Why does sodium form a 1 plus ion and magnesium 2 plus ion?

This is due to the difference between the two elements regarding their valence electrons as neutral elements. Sodium has a single electron in its valence shell, which it gives up to have a stable octet; by giving up one electron, sodium acquires a 1+ charge. Magnesium has two electrons in its valence shell that it will give up to have a stable octet; by giving up two electrons, magnesium acquires a 2+ charge.

Why is sodium a different element with different properties than magnesium?

Sodium has a charge of +1 in its ionized form while magnesium has a charge of +2 in its ionized form. This is due to the number of protons and electrons in each element. Having a different charge alters the types of reactions and products involved with that element.

Why sodium and magnesium form positive ions?

Sodium and magnesium form positive ions because they lose electrons in order to have a filled valence shell, like a noble gas. A sodium atom loses one electron so that its ion has a 1+ charge and the noble gas configuration of neon. A magnesium atom loses two electrons so that its ion has a charge of 2+ and the noble gas configuration of neon.

Due to one unit more nuclear charge and two binding electrons for Magnesium atom.


What is the sodium phosphate formula?

Sodium has a single positive charge (+), whilst phosphate ions have a 3- charge. To balance out the charges, three sodium ions are needed, so the formula will be Na3PO4.
