What is the Structure of an Ethene Molecule?

A carbon atom has 4 electrons in its outer shell.
Carbon is in group 4 of the periodic table.
A hydrogen atom has 1 electron in its outer shell.
Hydrogen can only form 1 bond.

The four hydrogen atoms will each share their 1 electron
with carbon to form four carbon - hydrogen covalent bonds.
The t
wo carbon atoms will each share
2 electrons
to form a carbon - carbon double bond
and make an ethene molecule (C2H4).

Ethene is commonly represented by the structural formula

where the double lines between the carbon atoms
represent a double covalent bond.
The single lines between the hydrogen and carbon atoms
represent single covalent bonds.
