What happens to the nuclear charge with increase in atomic number?

What Is atomic number?

The representation of Bohr model of elements with atomic number 3 to 9 in the second period of the periodic table. Is there are in the number of shells with the increase in atomic number?

The statement that is not correct for the periodic classification of elements is The properties of elements are periodic functions of their atomic numbers. Non-metallic elements are lesser in number than metallic elements. Electronegativity of the elements along the period from left to right increases in a regular manner. For transition elements the d-subshells are filled with the electrons monotonically with increase in atomic number.

Which of the following statements is correct with respect to the property of elements with an increase in atomic number in the carbon family (group 14)?
