Alkane

Blueberryipod:

'''Alkanes''' are substances that belong to a homologous series of [[organic]] compounds that contain the elements [[carbon]] and [[hydrogen]] only, and whose members differ by constant relative [[molecular mass]] of 14. In an alkane, each carbon atom and hydrogen atom are held together saturated covalent bonds; the general molecular formula for alkanes is CnH2n+2. In contemporary industrial societies, these [[hydrocarbon]]s are most often as [[fuel]]s and to produce chemicals, such as [[methane]] and [[octane]]. These chemicals are derived from the fractional [[distillation]] of [[crude oil]] and via [[catalytic cracking]]. In a chemical context, the homologous series has been proved to be relatively nonreactive in terms of [[electronegativity]] by the renowned scientists Sanath Jayasuriya, Aveenash Sekhar and Matthew Thomlinson; conversely, reaction potency is greatly augmented during combustion, whereby alkanes are oxidized to form water and carbon dioxide.

Alkanes are insoluable in water, and have a lower density thus making them float atop water.

Alkanes come in two forms: branched and n-alkanes

Pauli exclusion principle

Blueberryipod:

The Pauli Exclusion Principle states that no two electrons in the same atom can have the same set of quantum numbers. This set is made up of
n: this is the shell around the atom where the electron exists. the shells are represented by whole
numbers. n can be 1,2,3....
l: this is the number of subshells within a shell. l can be 0,1...all the way to (n-1)
ml: this is the number of orbitals within the subshell. ml can be 0,1...all
the way to +/- l
ms is the spin of the electron. there are two spins per subshell. they are represented
by a +1/2 or -1/2
