In the atomic volume vs atomic weight of the elements graph, which of the following elements occupies an ascending position on the curve?
Open in App
Solution
The correct option is C Cl
Most electronegative elements occupy the ascending positions on the curve. Therefore, Cl occupies an ascending position on the curve.
If we see the atomic mass versus atomic volume curve, we will notice the following features:
i) Alkali metals such as Na, K, Rb which have similar properties occur at peaks of the curve. He didn't mention alkaline earth metals.
ii) Halogen elements like F, Cl, Br which have similar properties occur at the rising or the ascending part of the curve.
iii) Noble gasses such as Ne, Ar, Kr which have similar properties occur just before the alkali elements.
iv) The atomic volume of the elements in a period initially decreases and then increases.
