(a) Electropositive nature of the element(s) increases down the group and decreases across the period
(b) Electronegativity of the element decreases down the group and increases across the period
(c) Atomic size increase down the group and decreases across a period (left to right)
(d) Metallic character increases down the group and decreases across a period
On the basis of the above trends of the periodic table, answer the following about the electron with atomic number 3 to 9
(a) Name the most electropositive element among them
(b) Name the most electronegative element
(c) Name of the element with smallest atomic size
(d) Name the element which is a metalloid
(e) Name the element which shows maximum valency.

To solve the question based on the periodic trends for elements with atomic numbers 3 to 9 (which are Lithium, Beryllium, Boron, Carbon, Nitrogen, Oxygen, and Fluorine), we will analyze each part step by step. ### Step-by-Step Solution **(a) Name the most electropositive element among them.** 1. **Understanding Electropositivity:** Electropositivity is the tendency of an element to lose electrons and form positive ions. It generally increases as you move down a group and decreases across a period from left to right. 2. **Identifying the Elements:** The elements in question are Lithium (Li), Beryllium (Be), Boron (B), Carbon (C), Nitrogen (N), Oxygen (O), and Fluorine (F). ...
