What are Chemical Bonds?
A chemical bond is a mutual attraction between the nuclei and valence electrons of different atoms that bond the atoms together.
Things to Keep in Mind
Atoms by themselves have extremely high potential energy, but nature favors low potential energy that is why atoms bond. The potential energy of an atom is lowered through bonding.
Kinds of Chemical Bonds
There are three main chemical bonds, ionic, covalent, and metallic. Each one has a unique set of characteristics and properties.
Ionic bonds are bonds that form from a metal and non-metal through a large number of anions and cations. The atoms in this bonds don't share the same amount of electrons, One atom will completely give up electrons in order for the other atom to be stable. Very strong bond. Ex. Calcium and Flourine.
Properties: Granular or powdery appearance, dissolve, high melting point, conduct only when melted or dissolved.
Covalent bonds form between a non-metal and a non-metal these atoms are kind and share their electrons equally. Pretty strong Bond. Ex. Sucrose.
Properties: Granular or powdery appearance, sometimes dissolves sometimes doesn't, low melting point, no conductivity.
Metallic bonds form between a metal and a metal. Weak bond. Ex. Mercury.
Properties: Shiny appearance, don't dissolve, high melting point, and conduct as a solid and liquid (Don't dissolve.)
