COMPOUND DEFINATION:
Chemical compound, any substance composed of identical molecules consisting of atoms of two or more chemical elements. methane molecule Methane, in which four hydrogen atoms are bound to a single carbon atom, is an example of a basic chemical compound.
A compound is a pure substance that consists of two or more elements held together in a fixed proportions by natural forces is called chemical bond
CHARACTERISTICS
- In a compound constituents are present in definite proportion by mass.
- The properties of a compound are different from the properties of its constituents.
- The constituents of a compound cannot be separated by simple physical processes.
- THERE ARE SOME CHARACTERISTICS OF COMPOUND
TYPES
THERE ARE THREE TYPES OF COMPOUNDS
1. IONIC
Ionic compounds are compounds made up of ions. These ions are atoms that gain or lose electrons, giving them a net positive or negative charge. Metals tend to lose electrons, so they become cations and have a net positive charge. Nonmetals tend to gain electrons, forming anions that have a net negative charge.
2.COVALENT COMPOUND
A covalent compound is a molecule formed by covalent bonds, in which the atoms share one or more pairs of valence electron
3. METALLIC COMPOUND
A metallic compound is a compound that contains one or more metal elements bonded to another element. Typically, the metal atom acts as the cation in the compound and is bonded to a nonmetallic anion or an ionic group. Because it has a positive charge, the metal element symbol is listed first in the
chemical formula.
EXAMPLES OF COMPOUND
- Water - Formula: H2O = Hydrogen2 + Oxygen. ...
- Hydrogen Peroxide - Formula: H2O2 = Hydrogen2 + Oxygen2 ...
- Salt - Formula: NaCl = Sodium + Chlorine. ...
- Baking Soda - Formula: NaHCO3 = Sodium + Hydrogen + Carbon + Oxygen3 ...
- Octane - Formula: C8H18 = Carbon8 + Hydrogen18
