Question

Please tell the answer *Question3*. It's urgent

Answer 1

1. From left to right the no. of protons inrease which means that Effective Nuclear Charge Increases and electrons and orbitals are more close to nucleus.

2. Li is the most metallic in nature as metals have tendency to lose electrons and act as positively charged ions and Li forms Li⁺ after donating an electron. Also electopositivity or metallic character decreases from left to right in a period.

3. Flourine is the most non metallic as metallic nature decreases and non metallic nature inreases from left tp right in a period. F forms F⁻ by accepting an electron as is stable with a negative charge.
