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.

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.
Does sodium and magnesium form an ionic compound?
No it forms Mg2+, a positive ion, as it is in group 2.
What simple ion does Magnesium form?
Mg2+
What happens when a magnesium ion is attracted to to a chlorine ion?
They form an ionic compound.
What is larger radius a sodium ion or chloride ion?
A chloride ion has a larger radius than a sodium ion, because the chloride has an additional complete valence shell of electrons compared to a sodium ion, but a sodium atom has lost the only electron in this valence shell that the sodium atom ever included to form a sodium ion.

What elements from the periodic tabe are in foods?
Calcium, Iron, Magnesium, Potassium, Sodium (but sodium in most cases be in the form as an Ion),
What is the metal that is found in your body in ion form?
Examples: sodium, potassium, calcium, magnesium etc.
Does sodium and magnesium form an ionic compound?
No it forms Mg2+, a positive ion, as it is in group 2.
How can you say that magnesium ion and sodium ion are similar in size?
Sodium ion is larger than magnesium ion. The electrons are more tighly bound in Mg2+. On a "diagonal relationship" Li and Mg are similar in size as are sodium and calcium
How do you precipitate magnesium ion out of 50-mL of 21 M solution of magnesium nitrate?
Add something that magnesium will form an insoluble compound with. Sodium sulfate or potassium carbonate, maybe.
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.
What is the concentration of Mg2 plus?
Magnesium, ion (Mg2+)
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 magnesium form its ion?
Magnesium loses two electrons.
Describe the structure of sodium chloride and magnesium oxide as solids?
Ionic Configuration. Each Sodium ion in contact with six other chloride ions and vice versa. Same with Magnesium Oxide. Both form a cuboid structure.
To form an ion does a sodium atom have to lose or gain a electron?
lose an electron, forms Na+, sodium with a charge of plus one.
