313050 Statement A :
According to Mendeleev, periodic properties of elements is a function of their atomic number.
Statement B :
Atomic number is equal to the number of protons.

313051 The first list of 23 elements was compiled in the late 1790s by

313052 The following are some statements about Mendeleev’s periodic table
(i) It is based on increasing order of atomic numbers.
(ii) Mendeleev corrected the atomic weight of some elements like Be, In etc
