Covalent bond

• A strong chemical bond that is formed when atoms share pairs of electrons

• To maintain at a constant overall total

• The smallest particle of an element that maintains the chemical identity of that element

• The mass of all reactants must equal the mass of all products. Matter is neither created nor destroyed.

Chemical energy

• The mass of all reactants must equal the mass of all products. Matter is neither created nor destroyed.

• To maintain at a constant overall total

• A strong chemical bond that is formed when atoms share pairs of electrons

• The energy that is stored in all compounds and potentially released in chemical reactions
