There are various kind of elements that are present in periodic table. Some elements are harmful, some are radioactive, some are noble gases. Therefore, the correct option is option A.
What is periodic table?
Periodic table is a table in which we find elements with properties like metals, non metals, metalloids and radioactive element arranges in increasing atomic number.
Periodic table help a scientist to know what are the different types of elements are present in periodic table so that they can **discover **the new elements that are not being discovered yet.
Within a period , an increase in atomic number is usually accompanied by a decrease in **atomic radius **and an increase in electronegativity .

As atomic number increases across a period in the periodic table, there is usually a decrease in atomic radius and an increase in electronegativity. This occurs due to the increasing positive charge in the nucleus attracting electrons more strongly. Therefore, the correct answer is option A.
