chemical bond CORRECT ANSWER the force that holds two atoms together Atoms gain stability when CORRECT ANSWER they share electrons and form covalent bonds. The stability of an atom, ion or compound is related to its energy: CORRECT ANSWER lower energy states are more stable Metals and nonmetals gain stability by CORRECT ANSWER transferring electrons (gaining or losing) to form ions that have stable noble-gas electron configurations. Another way atoms can gain stability is CORRECT ANS...

Organic chemistry: correct answer: The study of carbon-containing compounds except elemental carbon (diamond, graphite, coal), CO2, CO, carbonates, and cyanides. Inorganic chemistry: correct answer: Studies the elements and everything else. The principle components of food, fuels, wood construction, and clothing are organic compounds. Octet rule: correct answer: A chemical rule of thumb that reflects observation that atoms of main-group elements tend to combine in such a way that each a...

Chemistry Cumulative Review Latest Update Graded A+ Electronegativity The tendency of an atom to attract electrons in a chemical bond. It is not directly measurable. Metals have low electronegativity, meaning they do not hold onto electrons tightly and often lose them in reactions. Nonmetals have high electronegativity, meaning they hold onto electrons strongly and often gain electrons from other elements. Covalent Bond The sharing of electrons between two nonmetal atoms. ...
