Covalent Bond Formation
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
A covalent bond forms when two atoms share a pair of electrons, each atom counting that pair toward its own valence shell.
Show
Two hydrogen atoms each contribute one electron to a shared pair, forming the covalent bond in H2.
Watch for
Covalent sharing differs from ionic transfer: both atoms keep a claim on the electrons rather than one losing them.
