estion Answer What is the primary role of electrons in atoms? Electrons occupy the electron cloud surrounding the nucleus and are responsible for chemical bonding, reactivity, and the overall chemical properties of an element. How are electrons arranged in an atom according to the Bohr model? Ele
lved: Hydrogen (electronegativity ≈ 2.2), Oxygen (electronegativity ≈ 3.5). Electronegativity difference: 3.5 - 2.2 = 1.3 → polar covalent. Molecular shape: Bent (angular) due to lone pairs. Polarity conclusion: Water
