Magnesium

MgCl2 is the correct formula, or two atoms of Cl for each 1 atom of Mg. You could also say 2 moles of Cl atoms for every 1 mole of Mg atoms. The empirical formula should be written with the subscripts in lowest whole number terms.

Note that this formula is consistent with the fact that an Mg cation is Mg+2 and a Cl anion is Cl-1. Given these charges, a formula of MgCl2 is the one with the smallest whole number subscripts that will allow the charge of the compound to be zero.

See related question below for more details on how to find empirical formulas.

it is ionic bonding because magnesium is a metal and oxygen is not. ionic bonding occurs between a metal and non-metal

Magnesium salt it can cause severe diarrhea.

First ionization energy of magnesium = 870/ kj/mol

First ionization energy of phosphorous = 589 kj/mol

So, magnesium has the larger ionization energy required to pull the first valance electron. Do you know why?

when it reacts with leadoxide it become magnesuim oxide. this is because they lead and magnesuim have undergone a REDOx (reduction and Oxidation).

the lead has been reduced and they magnesium has be oxidised!!!!!

The products of a neutralization reaction are a salt and water.

As magnesium sulfate is an ionic compound, it creates an ionic lattice. Therefore it doesn't exist as seperate molecules.

The flashpoint for magnesium is 610°C (1130°F). Magnesium is highly flammable and can ignite at relatively low temperatures. Special precautions should be taken when handling magnesium to prevent fires.

word equation : magnesium + water --> magnesium hydroxide + hydrogen

chemical equation : Mg + 2H2O → Mg(OH)2 + H2

An ionic bond. A typical metal - non-metal compound.

Magnesium (Mg) reacts with Bromine (Br2) to form Magnesium Bromide (MgBr2) which has an ionic formula of Mg2+ (Br-)2.

Both are ions and we should consider the ionic radius, not the atomic radius.

Rubidium ion (Rb+) will have a larger IONIC radius than strontium ion (Sr2+).

Both ions have the same electronic configuration. But strontium ion has more number of protons in the nucleus. Hence it will have greater force of attraction between the nucleus and the valence electrons, resulting in smaller size.

ASk your doc about it...no one knows at the moment.

Examples are: Be, Al, Ti, V, Mn, Co, Ni etc.

insoluble in water, soluble in hot alcohol

Iron is one of the magnetic metal. It is used as a catalyst in Haber process to produce ammonia N2 + 3H2 ----------- 2NH3

Both Mg and Na have the same outer energy level (shell). Mg has one proton more than NA and one electron more. The charge on th eouter shell the effective nuclear charge is reduced by the inner core electrons, which are the ame in both cases So the pull experienced by the valence electrons towards the nucleus is more in the case of Mg than Na. Hence Mg has slightly smaller size (radius) than Na.

no magnesium is not harmful and magnesium is good for your kidneys

It can cause anxiety agitation and risk of heart attack and stroke!

Magnesium is an atom; but as an atom magnesium has 3 stable isotopes and ca. 18 artificial isotopes. And in solutions magnesium exist as the cation Mg2+. Therefore magnesium is atom, has isotopes and also can be ion.

Sodium has 11 protons and usually 12 neutrons in their nuclei but no electrons. Magnesium asIts nucleus must contain 12 protons and no electrons

magnesium is a purply substance. Although when this substance is burned with oxygen it becomes Magnesium Oxide. This chemical then turns into a black liquidy colour. The word equation for this experiment is: magnesium + Oxygen = Magnesium Oxide

To become an ion, an atom of magnesium (or anything else) will gain or lose one or more electrons. This will create an imbalance between the number of protons in its nucleus and the number of electrons it is "holding onto" in the electron cloud.

Aluminium has a greater number of electron shells and larger atomic radius, meaning that its pull on its outer electrons is less, meaning that they can flow more easily. Also, it has more electrons on its outer shell (3, rather than 1 or 2) meaning that there are more electrons to flow.
