Answer» o...I'll help u...A QUANTUM number is a value that is used when describing the ENERGY levels available to ATOMS and molecules. An electron in an atom or ion has four quantum numbers to describe its state and yield solutions to the Schrödinger wave equation for the hydrogen atom.The principal quantum number is an integer that is the number of the electron's shell. The value is 1 or higher (never 0 or negative).The angular momentum quantum number is an integer that is the value of the electron's orbital (e.g., s=0, P=1). ℓ is greater than or equal to zero and less than or equal to n-1.The magnetic quantum number is the orientation of the orbital with integer values ranging from -ℓ to ℓ. So, for the p orbital, where ℓ=1, m could have values of -1, 0, 1.The spin quantum number is a half-integer value that is EITHER -1/2 (called "spin down") or 1/2 (called "spin up").Hope it helps you..# BeBrainly |
