Chemical Bonds

In chemistry, reactions involve the breaking of existing chemical bonds and the formation of new ones. These reactions often start with reactants, which are the initial substances that undergo transformation, and result in products, the final substances formed.

Chemical Bonds

Nonpolar Covalent Bonds - A covalent bond of two atoms of the same element

Distribution of Electrons

Carbon Example

Hydrogen Bonds

Chemical Reaction - breaking existing chemical bond and creating new ones

Products - The final results after the conversion

Reactants - The conversion of starting material

Polar Molecule - has an unequal distribution of charges, Ex.) Water

Hydrogen Bond - Weak Bond,

Salt - Sodium Chloride

Electronegativity - measure of attraction for shared electrons

Molecule - 2 or more atoms held together

Covalent Bond - Shares electrons between them

Ionic Bond - the transfer of electrons

Chemical Bonds - Allow atoms to stay close together
