Answer from: paulesparsa6

- Hydrogen and chlorine.

Explanations:- A covalent bond forms between two non metals where as an ionic bond is formed between a metal and non metal.

Hydrogen and chlorine both are non metals so the bond formed between them is covalent.

Sodium is a metal and chlorine is a non metal so the bond formed between them is ionic.

Copper is a metal and bromine is a non metal so the bond formed between them is ionic.

Zinc is a metal and bromine is a non metal so the bond formed between them is ionic.

So, the only and only pair of elements that will form a covalent bond is hydrogen and chlorine.

Answer from: alexchou773pejk7x

The pair of elements that will form a covalent bond is Hydrogen and Chlorine .

Explanation:

The covalent bond is the chemical bond between atoms where electrons are shared, forming a molecule. Covalent bonds are established between non-metallic elements, such as hydrogen H, oxygen O and chlorine Cl. These 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. The shared electron pair is common to the two atoms and holds them together.

An ionic bond is produced between metallic and non-metallic atoms, where electrons are completely transferred from one atom to another. During this process, one atom loses electrons and another one gains them, forming ions. Usually, the metal gives up its electrons forming a cation to the nonmetal element, which forms an anion.

Taking into account the previous definitions, it is first necessary to know if the elements are metallic or non-metallic:

Hydrogen: Non-metallic atomChlorine: Non-metallic atomSodium: Metallic atomCopper: Metallic atomBromine: Non-metallic atomZinc: Metallic atom

Now you can determine the type of link of the following pairs of elements:

Hydrogen and Chlorine: Non-metallic atom - Non-metallic atom: Covalent Bond Sodium and Chlorine: Metallic atom - Non-metallic atom: Ionic Bond Copper and Bromine: Metallic atom - Non-metallic atom: Ionic Bond Zinc and Bromine: Metallic atom - Non-metallic atom: Ionic Bond

Finally, the pair of elements that will form a covalent bond is Hydrogen and Chlorine .
