Correct answers: 2 question: Which of the following accurately describes covalent bonds? But this is not the only way that compounds can be formed. In inorganic chemistry, covalent bonds are the most common type of bond, and atoms sharing electrons create a covalent bond, and further calculation can be defined as follows: One pure covalent bond is formed when two atoms with the same electronegativities come together. The result is known as a polar bond, an intermediate case between ionic and covalent bonding, with one end of the molecule slightly negatively charged and the other end slightly positively charged.
