Magnesium chloride is an ionic compound. Magnesium has 2 valence electrons, and chlorine has 7. According to the octet rule, each element will bond in such a way that it ends up having 8 electrons in its outer shell--either by adding electrons to its outer shell until it has 8, or by losing all the electrons in its outer shell (that way, the next-largest electron shell--which is already full--becomes the new outer shell). Since magnesium has 2 valence electrons, it will lose two electrons (it's easier to go 2 - 2 = 0 than to go 2 + 6 = 8). Chlorine has 7, so it will gain an electron and have a full (8-electron) outer shell. There must therefore be two chlorines for every magnesium: each chlorine accepts one of the two electrons donated by magnesium. Magnesium forms two ionic bonds: one to each chloride ion.

How many chlorine atoms are in MgCl2?
Three. Two chlorine atoms and one magnesium atom.
How many moles in 53.8 g of magnesium chloride?
Magnesium chloride, MgCl2, has a molecular mass of has a molar mass of 95.21 g/mol. So, 53.8 g MgCl / 95.21 g/mol is 0.565 mol MgCl2.
How many bonds does Be form?
Be or Beryllium can form up to two (2) bonds in its natural state.
How many electrons would magnesium lose if it reacted with fluorine?
Magnesium lose two electrons to form MgF2.
What elements can form a positive ion?
All elements can and many often do form positive ions.
How many elements are joined together to form magnesium chloride?
2. Mg and Cl
Is magnesium and chlorine a likely compound?
It's an actual, and common, compound - MgCl2 (magnesium chloride), a constituent of seawater, has many uses including just chasing off the chlorine atoms to recover the magnesium metal.
How many chloride ions are needed to cancel the 2 charge of magnesium in magnesium chloride (MgC12)?
Two.
How many chloride atoms will magnesium bond?
Magnesium atoms, which form divalent cations, can each bond ionically with two chloride ions, because chlorine atoms form anions with only one negative charge each. ("Chloride atoms" as written in the question do not exist: chlorine atoms form chloride ions by gaining one electron each from less electronegative atoms.)
How many bonds are there in ammonium chloride?
there are 4 bonds
What does the formula for the compound magnesium chloride MgCl2 tell you about how many chloride ions are needed to cancel out the charge of magnesium?
Two
How many chloride ions are present in a formula unit of magnesium chloride?
2
How many covalent bonds does element Mg form?
Magnesium often bonds ionically. It has 2 spare electrons in the outer shell (a charge of 2+) , so therefore has a valency of 2.magnesium can also bond covalently forming 2 bonds as in the Grignard reagent, ethyl magnesium bromide, C2H5MgBr. This is an organometallic compound.
How many atoms in magnesium chloride?
Three. Two chlorine atoms and one magnesium atom.
How many chlorine atoms are in MgCl2?
Three. Two chlorine atoms and one magnesium atom.
1.25 g of magnesium hydroxide are added to a 5.00 M solution of hydrochloric acid in a neutralization reaction that produces water and magnesium chloride How many grams of magnesium chloride are prod?
