apacity to engineer advanced materials at the atomic level, paving the way for innovations in electronics, energy, and structural applications. The insights gained from these labs not only deepen our fundamental understanding of matter but also
t: Electrons shared unequally due to differences in electronegativity (e.g., H₂O). Example: Water (H₂O) Oxygen shares electrons with two hydrogen atoms. The shared electrons spend more time around oxygen, creating a pol
Cl⁻ ions that attract each other. Covalent Bonds Covalent bonds involve the sharing of electron pairs between atoms, usually nonmetals. The shared electrons allow each atom to attain a stable electron configuration. Characteristics of Covalent Bonds: Form molecules like H₂, O₂, and CO₂. Can
hemical bond formed when one atom transfers electrons to another, resulting in oppositely charged ions that attract each other. What is a covalent bond? A covalent bond is a chemical bond formed when two atoms share one or more pairs of electrons. Wha
