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.
They form an Ionic compound.
+2 charge for magnesium ion
Magnesium, ion (Mg2+)
positive ion - magnesium(cation) negative ion-chloride (anion)
Magnesium exists in water as an ion (Mg2+), meaning it cannot be "filtered." You can get rid of magnesium in your well water (called "hard water") with a water softener.
the symbol for the magnesium ion is Mg2+
Magnesium once formed an ion the charge is 2+ .
Magnesium 2+
This means that there are two bromines in magnesium bromide, much like there are two hydrogens in water, H2O. This occurs because when magnesium forms an ion it has a charge of (+2), and when bromine forms an ion, it has a charge of (-1), Thus, it takes 2 bromines to neutralize the charge of the magnesium.
Magnesium forms a 2+ ion by giving away its two outermost electrons.
The charge on a magnesium ion with 10 electrons (Mg2+) is +2.
The positively charged magnesium ion and the negatively charged chloride ion.
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.
It depends if it the ion of magnesium, if it is the ion, then it is positive. If not, then it is neutral.
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.
Magnesium loses two electrons.
