Quantum Mechanical Model of the Atom- Introduction

Explain how electrons are organized in the atom

Describe energy levels, sublevels, and orbitals in an atom

Draw a representative shape of each sublevel

Determine the maximum number of electrons in each energy level, sublevel, or orbital

designated as "n", so n = 1, n= 2, n=3, etc.

Represents the average distance of an electron from the nucleus

The lower the number, the closer to the nucleus

Each energy level is divided into sublevels

3-D areas where the electron can exist in the atom

Labeled as s, p, d, f, and other letters where an electron can jump to if enough energy is added

n = 1: 1 sublevel, n = 2: 2 sublevels, etc

n = 1: 1 sublevel---s

n = 2: 2 sublevels---s & p

n = 3: 3 sublevels---s, p, & d

n = 4: 4 sublevels: s, p, d, & f

n = 5: 5 sublevels: s, p, d, f, & g but no electrons are in g in ground state

the sublevels have different energies: s<p<d<f in energy

Each sublevel has an orientation in space, each of these orientations are called an atomic orbital

Each orbital can hold a maximum of 2 electrons
