GENERAL CHEMISTRY QUESTIONS AND ANSWERS | LATEST UPDATE | 2024/2025 | GRADED A+ What is the difference between an ionic bond and a covalent bond in terms of electron transfer and sharing? An ionic bond involves the transfer of electrons from one atom to another, creating positively and negatively charged ions, whereas a covalent bond involves the sharing of electron pairs between atoms. How does the concept of atomic orbitals explain the bonding in molecules? Atomic orbitals des...

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. ...
