Electronegativity trend (p. 21) - correct answer Moving from left to right across a period, electronegativity INCREASES. Moving down a group from top to bottom, electronegativity DECREASES. Principal Quantum Number: "n" (p. 19) - correct answer Represents the shell an electron occupies, denotes the energy level or size of an orbital. Is the coefficient number in an electron configuration e.g. for 3p^2, n=3 Angular Momentum Quantum Number: "l" (p. 19) - correct answer Represents the sub...
