The electron sea model represents the way electrons exist in metals.
Two pairs of shared electrons represents a double covalent bond.
Each covalent bond has two electrons. A triple bond has three covalent bonds. Therefore a triple has six electrons.
It represents 2 valence electrons.
They share two electrons in a sigma bond (the kind of bond in a single bond) and two additional electrons in a pi bond (the bond that forms in a double bond). So in total, they're sharing four electrons in a double covalent bond.
The electron sea model represents the way electrons exist in metals.
Two pairs of shared electrons represents a double covalent bond.
A covalent bond that shares four electrons has a double bond between the atoms. A single bond is shown as a single dash, so a double bond is two dashes.
Each covalent bond has two electrons. A triple bond has three covalent bonds. Therefore a triple has six electrons.
They share two electrons in a sigma bond (the kind of bond in a single bond) and two additional electrons in a pi bond (the bond that forms in a double bond). So in total, they're sharing four electrons in a double covalent bond.
It represents 2 valence electrons.
Each dash represents a pair of shared electrons, 1 from each atom, that creates a (covalent) bond.

Four electrons (2 pairs) are shared in a double covalent bond.
Six electrons, 3 pairs of electrons.
electrons share ionic bond between atoms. Covalent bond may also be present.
covalent bond (There is also metallic bonding, which is many, many atoms sharing an electron, not just neighboring electrons.)
