sesenic [268]

Here we have to chose the correct statement which affect the discovery of the atomic number on the periodic table.

The discovery of the atomic number of the elements: C. It allowed the elements to be placed in strict order of increasing atomic number.

The use of X-ray determined the atomic number or number of electrons present in an element. The number of electrons is the basis of generate the periodic table, where the elements are arranged in terms of the number of electrons present in the atom in early stage of periodic table.

However in later the modern periodic table generated, which has group and period in terms of their property. Although the strictness on the increasing number of electrons are followed.
