The sharing amongst atoms is what type of bond

Covalent bond

Explanation:

The sharing amongst atoms leads to the formation of covalent bonds.

Covalent bonds are bonds formed between two or more atoms having zero or very small electronegativity difference. Such bonds exists in the molecules of non-metals.

Each of the atom tends to share the valence electrons in their outer energy levels to be able to mimic the noble gas structure. For the formation of this bond type, each of the atom requires odd or unpaired electrons.

can you list the answers so i can answer

your answer is a. the enthalpy of formation for a pure element in its standard state is always positive.
