Why do atoms form bonds?
Opposite charges attract
What type of atoms combine in an ionic bond?
A metal ion and a non-metal ion
What type of atoms combine in an covalent bond?
What does the octet rule state?
How does an Ionic transfer take place?
The metal atom gives electron(s) to the nonmetal atom, creating different charged ions. Opposite charged ions stick together, creating bonds
When 2 atoms share the electrons equally in a covalent bond, it is a
Nonpolar bond
Noble Gasses
What type of structure do Ionic bonds form?
A lattice structure
When multiple electrons do not share the electrons equally, it is a
Polar bond
Positive
What are properties of ionic compounds?
High melting points, and are hard and brittle
Diatomic molecules are always this type of bond
Nonpolar bond
An anion is an ion which is
Negative
Explain the concept of ionic compounds as formula unitsExplain the
An ionic formula unit contains a positively charged ion (cation) and a negatively charged ion (anion)
What are the properties of covalent compounds?
Exist as gasses or liquids or soft solids, and generally have a low melting/boiling point
