Since Mg needs to lose two valence electrons, it is required that two Cl atoms each gain one Mg valence electron. The Mg atom becomes a Mg 2+ ion and each Cl atom becomes a Cl− ion. The ionic bond
Why the magnesium ion has a charge of +2?
Magnesium has two electrons in its outer shell as it is in group 2 of the periodic table, which it loses, so its outer shell is full (2,8) and it has a charge of +2, as it still has 12 protons (positive charges) and now has only 10 electrons (negative charges).
What is the ion charge of MgCl2?
Magnesium Chloride Chemical Formula
It has a charge of +2 . Meanwhile, chlorine is willing to take in one electron giving it a charge of -1. However, two chlorine atoms are needed to take the two electrons from magnesium in order to complete it's octate.
What does the 2 in the formula for MgCl2 represent?
here is your answer !!! magnesium cloride is formed by sharing of electon . hence clorine have -1 valency . here , 2 represent the number of atom .
What is the 2 in MgCl2 called?
Magnesium chloride is the name for the chemical compound with the formula MgCl 2 and its various hydrates MgCl 2 (H 2 O) x .
Why does a Mg atom have 2+?
Explanation: 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.
What is ion charge?
An ion is a charged atom or molecule . It is charged because the number of electrons do not equal the number of protons in the atom or molecule. An atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom.
Is MgCl2 acid or base?
The salts of strong acid and weak base give acidic solutions . Magnesium chloride is slightly acidic because it is formed by the reaction of a relatively weak base. Thus MgCl 2 is slightly acidic in nature.
Is MgCl2 a salt?
Magnesium dichloride is a magnesium salt comprising of two chlorine atoms bound to a magnesium atom. It is a magnesium salt, an inorganic chloride and a magnesium halide.
How do I get MgCl2?
Magnesium chloride is mined from sea beds , and hydrated magnesium chloride is extracted from sea water. Extract magnesium hydroxide from sea water. Add slaked lime (CA(OH2)) to sea water to the magnesium (Mg2+) ions to fall out of the solution as the precipitate magnesium hydroxide.
What happens when MgCl2 is heated?
When heated, this hydrolyses to give magnesium oxide and hydrogen chloride gas . The fused chloride is electrolysed to produce magnesium and it is also used for fireproofing wood, in magnesia cements and artificial leather, and as a laxative.
What is Fe2 SO4 3 called?
Iron(III) sulfate (or ferric sulfate) , is a family of inorganic compounds with the formula Fe2(SO4)3(H2O)n. A variety of hydrates are known, in fact are the most commonly encountered form of “ferric sulfate”. Solutions are used in dyeing as a mordant, and as a coagulant for industrial wastes.
Is rb2o soluble in water?
| Names | Density 4 g/cm 3 | Melting point >500 °C | Solubility in water Reacts violently to give RbOH | Magnetic susceptibility (χ) +1527.0·10 − 6 cm 3 /mol |

Which is a polyatomic ion?
Polyatomic ions are ions which consist of more than one atom . For example, nitrate ion, NO 3 – , contains one nitrogen atom and three oxygen atoms. The atoms in a polyatomic ion are usually covalently bonded to one another, and therefore stay together as a single, charged unit.
