(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 increases 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 elements with atomic numbers 3 to 9.
Name the most electropositive element among them.

Explanation

To determine the most electropositive element among those with atomic numbers 3 to 9, we will follow these steps:

### Step 1: Identify the Elements
The elements with atomic numbers 3 to 9 are:
- Atomic number 3: Lithium (Li)
- Atomic number 4: Beryllium (Be)
- Atomic number 5: Boron (B)
- Atomic number 6: Carbon (C)
