6 or 7 electrons in their outer levels. Atoms that have 4 electrons in the outer most energy level will tend neither to totally lose nor totally gain electrons during interactions. The Periodic Table of Elements will show you the electron configuration for any element you click on. The atomic orbitals of the hydrogen atom can be visualized as a cloud around the nucleus. The orbital represents a probability of finding the electron at a particular location.
Darker regions signify a greater probability.
2s Atomic orbitals do not always have the shape of a sphere. Higher orbitals have very unusual shapes. 2px 3px These orbitals were prepared by Dr. Yue-Ling Wong from the University of Florida for more images click here. The Structure within the Atom Visualization of atomic orbitals. Quantum Theory .
