Only the outer electrons are shown in the dot and cross diagrams below (2 inner electrons of carbon not shown).
Carbon's electrons are 2.4 and hydrogen just 1
Two electronic diagrams for ethane C2H6
and dot and cross Lewis diagrams of ethane
and ethane's displayed formula these three are 2D diagrams
and stick and ball 3D diagram of ethane
3D space filling model of ethane
Venn diagram style of showing the bonds in ethane.
I hope you like the atomic colour coding - xref physics!
Alkanes are relatively small molecules in which all the chemical bonds are covalent bonds.
All the bonds in alkane molecules are single bonds i.e. C–C carbon – carbon or C–H carbon – hydrogen.
Each carbon atom forms four single covalent bonds and hydrogen atoms form one single covalent bond.
All single bonds are formed by sharing a pair of electrons e.g. one from each of a carbon atom and a hydrogen atom, or two carbon atoms contributing (sharing) an electron each to the covalent bond.
