What is the total number of electrons in a Mg^(2+) ion? - Socratic
2016年12月7日 · #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 ...
What is the Lewis Dot Structure for #Mg_2^+#? - Socratic
2017年2月4日 · This is the MO diagram for the NEUTRAL "Mg"_2 dimer: Take one valence electron out of the antibonding sigma_(3s)^"*", and we have a bond order that changed from 1/2(2 - 2) = 0 to 1/2(2 - 1) = 1/2. Thus, MO theory suggests that "Mg"_2^(+) is more stable than "Mg"_2. If you mean "Mg"^(2+), it has no valence electrons, so there is not much of a ...
Does the Mg+2 ion have the same electron configuration as neon?
2015年1月13日 · 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, …
What is the balanced chemical equation that describes the
2014年7月14日 · 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 …
What are the spectator ions in Mg(s) + Zn^(2+) + 2NO_3
2016年6月18日 · The nitrate anions, "NO"_3^(-). A spectator ion is an ion that is present on both sides of a chemical equation. In other words, in order for an ion to be a spectator ion, it must exist as such as a reactant and as a product in the balanced chemical equation. You're dealing with a single replacement reaction in which magnesium metal, "Mg", replaces the zinc cations in zinc …
Is "Mg"^(2+) a Lewis Acid or Lewis Base? - Socratic
2016年10月7日 · 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.
Which ion has the largest radius? "Na"^(+), "Ga"^(3+), "K"^(+), …
2018年6月18日 · "K"^"+" has the largest radius. > The ionic radii of cations follow the same trends as atomic radii. They increase from top to bottom and from right to left in the Periodic Table. (Adapted from ermannhonors.wikispaces.com) Thus, the ion with the largest radius is closest to the lower left corner of the Periodic Table, and that is the "K"^"+" ion.
How would you arrange the ions N^-3, O^-2, Mg2+, Na+, and F
2016年5月13日 · How would you arrange the ions #N^-3#, #O^-2#, Mg2+, Na+, and F- in order of increasing ionic radius? Chemistry The Periodic Table Periodic Trends in Ionic Size 1 Answer
What is the electronic configuration of Mg^(2+) ion? | Socratic
2017年11月13日 · 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.
How do you balance HBr + Mg(OH)_2 - H_2O? | Socratic
2016年4月1日 · Let the equation be a HBr + b Mg(OH)_2 -> c MgBr_2+d H_2O Equating H-atoms on both sides, a+2b=2d Equating ...
