Subscript in the chemical formula suggest the variety of atoms the the element immediately prior to the subscript.

You are watching: In the compound mgcl2, the subscript 2 indicates that

In MgCl₂ there are two(2) atoms of chlorine because Subscript 2 is immediately after chlorine.


Answer : The correct option is D.

Explanation :

The given compound is .

When is dissolve in water climate they dissociates into two ions such together magnesium ion and chloride ion.

It is stood for as,


*

The fee on magnesium ion is +2 and also on chloride ion is -1. To neutralize the charge on magnesium ion, 2 chloride ions should be used.


In , the subscript 2 suggests that

*

Further Explanation:

The attraction in between atoms, molecule or ion which outcomes in the development of chemical compounds is well-known as a chemistry bond. That is created either due to electrostatic pressures or through the sharing of electrons. There are many strong bonds such together ionic bonds, covalent bonds, and metallic bonds while part weak bonds like dipole-dipole interactions, London dispersion forces, and hydrogen bonding.

Ionic compounds are the compounds that are formed from the ions of the corresponding species. Ions room the types that are developed either because of loss or get of electrons. A neutral atom develops cation through the ns of electrons and anion by the obtain of electrons.

There is development of ionic bond in situation of . Magnesium, being a steel loses two electrons and is formed. These electrons are embraced by 2 chlorine atoms and also two ions room formed.

The dissociation of occurs as follows:

Here, one and two room formed. This shows that there are two chlorine ion for each magnesium ion. For this reason the subscript in the chemical formula the shows the presence of 2 chlorine atoms every ion of magnesium. This indicates statement A is incorrect and also statement D is correct.

The chemistry formula of the compound has actually nothing to carry out with the size of the ion formed during the link formation. So subscript offers no idea around the dimension of the ions. This means statement B is incorrect.

A covalent link requires mutual sharing of electrons in between the external inspection atoms. Yet there is an ionic link formation between magnesium and also chlorine early to distinction in their electronegativities. So a dual covalent bond can not be formed between chlorine and also magnesium. This means statement C is incorrect.

The correct answer is answer choice D, there space two chloride ions for every magnesium ions. Subscripts constantly indicate the number of atoms, or ions, present in the molecule. The 2 describes the facet directly to its left, so answer choice A is reversed; there are 2 chloride ions for each magnesium ion, no the other means around. Answer selection B and C are incorrect because the subscript refers to the number of atoms, not the dimension of the atom or the type of bond.
