Magnesium has the chemical symbol Mg. If we see Mg2 in an expression or formula, we know that there are 2 atoms of magnesium in the expression or formula. That's the way it appears in Mg2RuH4. There is also (and probably most commonly) those times we encounter the ion of magnesium, and Mg+2 is our way of writing that. The magnesium has loaned out its two valence electrons, and has formed a compound according to its nature (and it's now in its +2 oxidation state). An example of magnesium in compound is MgO, which is the oxide of magnesium, magnesium oxide.
it might be because the signs are based on the i forgot i think europoeians word of it. so mg might stand for magnesium in Europe. not the real word it is just the letter of it.
Magnesium gets its symbol (Mg) from its name: magnesium.
Magnesium gets its name from Magnesia, a location in ancient Greece.
Because it's an element and that's its symbol. If you're asking why the symbol for magnesium is Mg rather than, say, Ma ... because it is.
the symbol for the magnesium ion is Mg2+
Mg2+
It depends if it the ion of magnesium, if it is the ion, then it is positive. If not, then it is neutral.
Magnesium's charge is 2+.
MgSO4 due to the combination of a Mg2+ ion and a SO42- ion.
the symbol for the magnesium ion is Mg2+
Mg2+S2-
Mg2+
Mg2+
Mg is the symbol for the element magnesium and could be used to represent a neutral atom of magnesium. Mg2- does not occur, but Mg2+ does, and is the symbol of a magnesium ion, which is a magnesium atom that has lost two electrons.
Mg2+
Mg2+
It depends if it the ion of magnesium, if it is the ion, then it is positive. If not, then it is neutral.
Magnesium that has lost 2 electrons.
Mg2+ exists in aqueous solution when a magnesium salt has been dissolved. When added to water: MgCl2 (s) => Mg2+ + 2Cl-
Mg, magnesium forms compounds containing Mg2+ ion.
Lol definitly the same person. The answer is Mg.
