Chemistry is mostly the study of electron interactions between atoms and molecules. Understanding the behavior of the electrons in an atom, such as, is an important part of understanding. Used the idea that an atom's electron followed the same rules as a mini solar system where the planets were electrons orbiting a center proton sun. Electric attractive forces are much stronger than gravitational forces, but follow the same basic inverse square rules for distance. Early observations showed the electrons were moving more like a cloud surrounding the nucleus rather than an individual planet.

While Orbital has now begun development of a next generation IRIS solution, this order, worth approximately $1.4 million, calls for the design, construction and delivery of a further 13 IRIS-RTU systems and associated electrical kiosks.

The shape of the cloud, or orbital, depended on the amount of energy, and magnetic moment of the individual electron. The properties of an atom's are described by four: n, ℓ, m, and s.

The more energy you give a body in orbit, the further 'out' it goes. If you give the body enough energy, it will leave the system entirely. The same is true for an electron orbital. Higher values of n mean more energy for the electron and the corresponding radius of the electron cloud or orbital is further away from the nucleus. Values of n start at 1 and go up by integer amounts.

The higher the value of n, the closer the corresponding energy levels are to each other. If enough energy is added to the electron, it will leave the atom and leave a behind. The is the angular quantum number, ℓ.

Each value of n has multiple values of ℓ ranging in values from 0 to (n-1).This quantum number determines the 'shape' of the. In chemistry, there are names for each value of ℓ. The first value, ℓ = 0 called an s orbital. S orbitals are spherical, centered on the nucleus. The second, ℓ = 1 is called a p orbital. P orbitals are usually polar and form a teardrop petal shape with the point towards the nucleus. ℓ = 2 orbital is called a d orbital.

These orbitals are similar to the p orbital shape, but with more 'petals' like a cloverleaf. They can also have ring shapes around the base of the petals.

The next orbital, ℓ=3 is called. These orbitals tend to look similar to d orbitals, but with even more 'petals'. Higher values of ℓ have names that follow in alphabetical order. The third quantum number is the magnetic quantum number, m. These numbers were first discovered in spectroscopy when the gaseous elements were exposed to a magnetic field. The spectral line corresponding to a particular orbit would split into multiple lines when a magnetic field would be introduced across the gas. The number of split lines would be related to the angular quantum number.

This relationship shows for every value of ℓ, a corresponding set of values of m ranging from -ℓ to ℓ is found. This number determines the orbital's orientation in space. For example, correspond to ℓ=1, can have m values of -1,0,1.

This would represent three different orientations in space for the twin petals of the p orbital shape. They are usually defined to be p x, p y, p z to represent the axes they align with.
