Answer: Option (a) is the correct statement.
Explanation:
A substance that has two or more number of different atoms which are chemically combined to each other in a fixed ratio by mass is known as a compound.
For example,
Here, contains one atom of calcium and two atoms of chlorine which are chemically combined together in 1:2 ratio. Therefore, it is a compound.
Also, both chemical and physical properties of will be different from Ca and
.
Thus, we can conclude that the statement atoms are bonded together, and the compound has different physical and chemical properties than the individual element, is correct.
Answer: In a compound with molecular formula ,the valency of Y and X are 2 and 3 respectively.
Explanation:
For formation of a neutral ionic compound, the charges on cation and anion must be balanced. The cation is formed by loss of electrons by metals and anions are formed by gain of electrons by non metals.
The given compound is where X and Y combine and their oxidation states or valencies are exchanged and written in simplest whole number ratios. Thus the oxidation state or valency of X is 3 and that of Y is 2.
