Question

Elements X and Y belong to group 16 and 2 respectively.Both belong to same period.write the formula of the compound formed by X and Y . what is the chemical nature of this compound?​

Answer 1

Explanation:

Electronic configuration : X (Z = 12), 2, 8, 2

Electronic configuration : Y (Z = 16), 2, 8, 6

Both these elements are present in third period since they have three electron shells. These are likely to form an ionic bond as a result of transference of two electrons from element X to the element Y. The compound will form compound XY.

Answer 2

Concept introduction:

Metal oxides are basic in nature. Groups are the names given to the periodic table's columns. In the table, individuals who belong to the same group make bonds of the same kind and have an equal amount of electrons in their atoms' outermost shells. Periods are the horizontal rows.

Explanation:

Given that, Elements X and Y belong to group $16$ and $2$ respectively. Both belong to same period.

We have to find, formula and chemical nature of the compound.

According to the question,

X belongs to group $16$ hence its valency must be $-2$ and Y belongs to group $2$ hence its valency must be $2$. Therefore formula of compound is XY and it is most probably metal oxide hence it is basic in nature.

Final Answer:

Formula of compound is XY and it is most probably metal oxide hence it is basic in nature.
