Types of Bonds

There are two main types of bonds that atoms can form Covalent Bonds Ionic Bonds

Covalent Bonds Occur between a non-metal and another non-metal H2O – Hydrogen and Oxygen Occurs when atoms share electrons with one another

Ionic Bonds Occur between a metal and a non- metal NaCl – Sodium and Chlorine Occurs when an atom gives an electron to another atom

Ionic Bonds cont. Bonding is based on the electron charges of an atom This can be found on the periodic table of elements

Ionic Bonding cont. Sodium has a charge of +1 Chlorine has a charge of -1 To be happy, an atom should be neutral (0 charge) Sodium has an extra electron charge, chlorine needs one Becomes NaCl (Table salt)

Ions We call atoms that have a positive or negative charges ions Cation: ion with a positive charge (+) Anion: ion with a negative charge (- )
