Question

which of the following statement is wrong about Lothar-Meyer's plot between atomic volume against atomic weight?
1) alkali metal occupy peaks on the curve.
2) Halogen atom occupy ascending positions on the curve.
3) Alkaline earth metals occupy descending position on the curve.
4)He proposed that physical properties of the element are a periodic function of their atomic numbers.​

Answer 1

Answer:

1. true

The most strongly electropositive alkali metal occupy the peaks on the curve.

2. true

The most electronegative elements i.e. halogens occupy the ascending position on the curve.

3. true

The less strongly electropositive alkaline earth metals occupy the descending position on the curve. 

4. true

According to Mendeleev, periodic properties of elements are periodic function of their atomic number.
