Answer:
The answer is: 1. a chemical bond between atoms with similar electronegativities covalent bond.
Explanation:
If the electronegativity of the atoms that form the bond is similar, the electrons in the bond will be shared almost equally and a covalent bond will form. If the difference is very large, the electrons will be transferred to the most electronegative atom, forming an ionic bond.
The answer is: 1. a chemical bond between atoms with similar electronegativities covalent bond.
