Question

A covalent compound formed between an element in period 1 and a halogen

Answer 1

It's HCL....formed with hydrogen and chlorine by covalent bond

Answer 2

Answer:

A covalent compound formed between an element in period 1 and a halogen can be Hydrogen Chloride, HCl

Explanation:

Hydrogen is the first element of period 1, with atomic number 1. And, Chlorine is a halogen belonging to period three, group 17 of halides.

Chlorine has a higher electronegativity than hydrogen, but the attractive force of chlorine atoms on electrons is insufficient to remove electrons from hydrogen. As a result, hydrogen chloride bond electrons are unevenly distributed in polar covalent bonds.
