What type of chemical bond is formed between two atoms of bromine 1. metallic 2. hydrogen 3. ionic 4. covalent

4 covalent ---because bromine is a non-metal and each atom must share electrons in order to satisfy the octet rule. In a covalent bond, two atoms share a pair of electrons. IOnic bonds form as a result of the transfer of electrons from one atom to another.

A covalent bond is formed between two atoms of bromine.

Explanation:

The covalent bond is the chemical bond between atoms where electrons are shared, thus forming a single unit called a molecule. Covalent bonds are established between non-metallic elements, such as hydrogen H, oxygen O and chlorine Cl.  Atoms interact with each other through the outermost electrons forming bonds.This is, the elements have many electrons in their outermost level (valence electrons) and have a tendency to gain electrons to acquire the stability of the electronic structure of noble gas.   In other words, atoms tend to share electrons  to reach 8 electrons in the valence layer (last layer) to achieve stability.

Bromine is a nonmetal. So, a covalent bond is formed between two atoms of bromine.

the answer is c.the valence of the atoms combine .
