Magnesium is very useful for alloys. We use it for make medicines. Mg has a mass number of 24.
There are 10 electrons in Mg2+ because the atomic number of magnesium is 12, which means it normally has 12 electrons. When it forms a 2+ ion, it loses 2 electrons, leaving 10 electrons in the Mg2+ ion.
Mg2+: [1s22s22p6]
Magnesium, ion (Mg2+)
The correct name of the ion Mg2+ is magnesium ion.
The Mg2 plus cation has 10 electrons.
This is a basic stoichiometry question. Things you need to know:1 mol = 6.022 x 10^23 atoms/particles/molecules/ionsRatio of Mg in MgCl2 : 1mol Mg2+/1 mol MgCl2Always start with what you are given:3.00 mol MgCl2 X 1mol Mg2+/1 mol MgCl2 X 6.022 x 10^23 ions Mg2+/ 1mol Mg2+=1.8066 x 10^24 ions Mg2+
An Mg2+ ion is a magnesium ion that has a charge of +2, meaning it has lost 2 electrons. The number of neutrons in an Mg2+ ion is the same as in a regular magnesium atom, which is 12 neutrons.
There are 10 electrons in Mg2+ because the atomic number of magnesium is 12, which means it normally has 12 electrons. When it forms a 2+ ion, it loses 2 electrons, leaving 10 electrons in the Mg2+ ion.
The cation for MgCl2 is Mg2+.
Mg2+: [1s22s22p6]
Magnesium, ion (Mg2+)
The number of protons is 12, the number of electrons is 10, the number of neutrons is different for each isotope.
10
There are 1.20 equivalents in 0.60 mole of Mg2+, since Mg2+ has a charge of 2+.
The correct name of the ion Mg2+ is magnesium ion.
The Mg2 plus cation has 10 electrons.
Mg equals Mg2+ plus 2e-
