A. Atoms of chlorine (Cl)
Explanation:
The atoms of chlorine are held together by non-polar covalent bonds.
- Covalent bonds are formed between two or more atoms having zero or very small electronegativity difference.
- For homonuclear molecules where the two bonding atom are of the same kind, the electronegativity difference is zero.
- This covalent bond type is called non-polar covalent bond.
- In this bond type, there is equal sharing of the electron pair between the atoms and there is no electrostatic charge on the molecule.

Explanation:
Bromine is a chemical element with the symbol Br and atomic number 35. It is the third-lightest halogen, and is a fuming red-brown liquid at room temperature that evaporates readily to form a similarly coloured vapour. Its properties are intermediate between those of chlorine and iodine. Isolated independently by two chemists, Carl Jacob Löwig (in 1825) and Antoine Jérôme Balard (in 1826), its name was derived from the Ancient Greek βρῶμος ("stench"), referring to its sharp and disagreeable smell.

Answer:
An atom consists of a positively charged nucleus, surrounded by one or more negatively charged particles called electrons. The positive charges equal the negative charges, so the atom has no overall charge; it is electrically neutral.
