A Binary Compound
A binary compound is formed from two types of elements - their states of matter result in the following types of compound :
Metal + Metal = Metallic Compound
Metal + Non-Metal = Ionic compound
Non-Metal + Non-Metal = Covalent compound
Types of Compounds - Categories - Ionic, Molecular and Acids
Most types of compounds fall in to one of three categories called ionic compounds, molecular compounds, or acids.
Types of Compounds - Ionic, Cations, Anions
An Ion is an atom, or group of atoms, that bears an electric charge. The types of compounds referred to 'Ionic compounds' consist of combinations of positively charged ions called CATIONS (which are usually metals - pronounce as 'cat-ion') and negatively charged ions called ANIONS (which are usually non-metals - pronounce as 'an-eye-on'). In general, a compound will have no charge.
Positively charged ions are called cations because they migrate towards the cathode (negative pole) in solution - they tend to lose electrons and form cations
Negatively charged ions are called anions because they migrate towards the positive pole (anode) and are therefore known as anions - non-metals tend to gain electrons and form anions
The positive cations and the negative anions then attract each other to form ionic bonds.
Ionic compounds conduct electricity when dissolved in water or when molten
Types of Ionic Compounds
Examples of different types of Ionic Compounds are:
NaCl (Sodium Chloride)
CaBr2 (Calcium Bromide)
Types of Compounds - What is the difference between a compound and a molecule?
Molecular compound. What is the difference between a compound and a molecule?
A molecule is formed when two or more atoms join together chemically
A compound is a molecule that contains at least two different elements
All compounds are molecules, but not all molecules are compounds
Types of Compounds - Molecular Compound
Molecular compounds consist of combinations of non-metals. A Binary molecular compound is composed of only two elements. Examples: H2O (water).
Molecular compounds are easy to identify, as they consist merely of two non-metal elements
Molecular compounds are non-conductors of electricity
