Sharing of electrons. Generally this involves pirs of electrons forming bonds.
Atoms share electrons in covalent bonds.
Sodium chloride has ionic bonds.
Animo acids
Two pi bonds and one sigma bond.
convalent bonds have the greatet bond energy.
Animo acids
Convalent bonds
Oxyanions such as sulfate, phosphate and permanganate, any alkene, oxygen molecule are some of the examples for compounds which have double bonds in them.
Convalent bonds (atoms all sharing their electrons), metallic bonds (a rigid crystal lattice bond), and ionic bonds (opposite electric charges-cation=+ anion=--that bond).
Electrons are transferred from one atom to another.
The Oxygen and the Hydrogen atoms are held together by Covalent bonds and the Calcium is held together with Ionic bonds.
