Question

Which of the following is a property of Strontium chloride?
A) Ionic substance
B) Non polar covalent substance
C) Polar covalent substance
D) Macromolecule substance
E) Metallic substance

Answer 1

We have to know that the strontium belongs to s block elements in the periodic table and it is also known as alkaline earth metals i.e. group II whereas chlorine belongs to halogen family which is group $17$, having high electron affinity and also electronegativity greater than bromine and iodine. An ionic bond is formed between strontium chloride.

Complete answer:
We must remember that an ionic bond is formed between strontium chloride. Strontium is a metal whereas chlorine is a non metal and a bond between these two atoms is an ionic bond. The salt has a chemical formula $SrC{l_2}$ . We also know that the strontium has a valency of $+ 2$ whereas chlorine has a valency of $- 1$ as it belongs to group $17$ which is only one electron less to attain stable electronic configuration. Thus electrons transfer within themselves and form a chemical bond and the bond is known as ionic bond.
Option A is a correct option for this question.

Note:
We have to know that the strontium chloride has a resemblance of structure which is strontium fluoride. It is an inorganic salt that can be produced through chemical methods. Strontium chloride forms a neutral salt. It is colorless to white crystalline powder and soluble in water. $SrC{l_2}$ is used in metallurgy and glass making. We must remember that it is not flammable and does not react with other chemical species. This compound is red in color and it is less toxic in nature.
