Which general trends in atomic radius and electronegativity are observed as the elements in period 3 are considered in order of increasing atomic number?atomic radius decreases and electronegativity increases.atomic radius increases and electronegativity decreases.both atomic radius and electronegativity increase.both atomic radius and electronegativity decrease?

A periodic Table is the systematic arrangement of the elements based on general trends. The electronegativity decreases in the group and increases through periods, whereas atomic radius decreases across periods and increases across the group.

The atomic number is defined as the number of protons present in the nucleus of every atom of that element. In the modern periodic table, the elements are listed based on the increasing atomic number, such that some of the trends are followed as:

The electronegativity of an element is defined as the ability of an atom to attract or share electrons. The electronegativity with an increase in atomic number increases across a period and decreases across the group.

The atomic radius is defined as the distance of nuclei of two atoms in a bond. The atomic radius with an increase in atomic number generally increases across the group and decreases across the period.

Therefore, the electronegativity increases across the period, and atomic radius increases across the group.
