Jan 13, 2015 · Yes, the "Mg"^(2+) ion and the neutral neon atom are isoelectronic, which implies that they have the same number of electrons and, of course, the same electron configuration. Magnesium has an atomic number of 12, which means its neutral atom has 12 electrons. The "Mg"^(2+) ion is formed when the neutral magnesium atom loses 2 electrons, which brings its …

Mar 1, 2016 · Because magnesium is a metallic element that tends to loss electron to achieve stability. Magnesium is under group 2 that also has a valence electron of 2. To achieve stability and to follow the octet rule, these 2 electrons in the outer shell will be removed making this atom into an ion with a 2+ charge. Mg^-6 is impossible in this case, because only nonmetallic …

Apr 4, 2015 · Magnesium is located in period 3, group 2 of the periodic table, and has an atomic number equal to 12. This means that a neutral magnesium atom has 12 electrons that surround its nucleus. When magnesium loses two of its electrons, it becomes the Mg^(2+) cation, which implies that the total number of electrons will decrease by 2. As a result, the electron …

Dec 7, 2016 · #1s^2 2s^2 2p^6 3s^2# Recall that the superscripts tell us how many electrons occupy each orbital, so adding all the superscripts will tell us how many electrons we have. So if you add them up, then subtract two to account for the 2+ ionic charge, you will get the right number of electrons. In either case, you will end up with #12-2 = 10 ...

Mar 11, 2017 · There are 12 protons and 10 electrons in a "Mg"^(2+) ion, the normal amount of neutrons is 12. Magnesium is an element with atomic number 12. This means that every magnesium atom will have 12 protons. In a magnesium atom, there are 12 electrons, to make the atom have a neutral charge. When an ion is formed, the magnesium atom loses electrons. The …

Nov 1, 2015 · 2H_3PO_4 + 3Mg(OH)_2 = Mg_3(PO_4)_2 + 6H_2O I can either tally all the atoms one by one or use my knowledge of ionic bonds to make the tally system much simpler. I'll do the simpler version. First re-write the chemical equation to avoid confusing myself: H_3PO_4 + Mg(OH)_2 = Mg_3(PO_4)_2 + H-OH Notice that I had shown the line structure between ...

Nov 13, 2017 · For example, look at Na (Sodium) and Mg (Magnesium) on the periodic table below. They are right next to each other. If we say Na+, we are losing one electron, therefore going reverse, not forward. Consequently, we would land on Ne, Neon. If we do the same thing for Mg2+ by going back 2 elements (because it is 2+), we also land on Ne.

Jul 14, 2014 · The equation is "Mg(OH)"_2"(s)" ⇌ "Mg"^"2+""(aq)" + "2OH"^"-""(aq)". > "Mg(OH)"_2 is a strong base. "Mg" is a Group 2 Metal, so it form "Mg"^"2+" ions. Each ion pairs up with two "OH"^"-" ions to form the neutral compound, "Mg(OH)"_2. Magnesium hydroxide is "insoluble", so only a small amount it goes into solution. But every bit that goes into solution …

Oct 7, 2016 · So, reasonably it should be an electron pair acceptor, and thus a Lewis acid. And while we write #Mg^(2+)#, in water we also write #Mg^(2+)(aq)#, by which we mean #[Mg(OH_2)_6]^(2+)#, which is, if you like, a coordination complex of #Mg^(2+)#. In ether and THF, the magnesium centre is also solvated in this way.

Nov 5, 2015 · Place a coefficient of 6 in front of "H"_2"O" on the right side. "2H"_3"PO"_4" + 3Mg(OH)"_2rarr"Mg"_3"(PO"_4)_2 + "6H"_2"O" Balance the "O". There are fourteen oxygen atoms on both sides of the equation, so it is already balanced.
