Differbetween
Substances can be categorised as either elements or compounds. Both of these are made up of atoms, the only difference is an element is made of one type of atom whereas compounds are made of two or more different types of atoms.

What is the different between element and compound?
An element is a material that consists of a single type of atom. Each atom type contains the same number of protons. Chemical bonds link elements together to form more complex molecules called compounds. A compound consists of two or more types of elements held together by covalent or ionic bonds.
What are examples of compounds and elements?
Elements, mixtures and compounds
Common examples include carbon, sulfur, oxygen, iron, copper, aluminium. Elements are represented by symbols. Compounds are substances made from atoms of different elements joined by chemical bonds. They can only be separated by a chemical reaction.
What are compounds 10 examples?
Compounds Examples
- 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
What is a compound simple definition?
A compound is a material formed by chemically bonding two or more chemical elements. The type of bond keeping elements in a compound together may vary: covalent bonds and ionic bonds are two common types.
What are the 4 types of compounds?
Types of Compounds
- Metal + Nonmetal —> ionic compound (usually)
- Metal + Polyatomic ion —> ionic compound (usually)
- Nonmetal + Nonmetal —> covalent compound (usually)
- Hydrogen + Nonmetal —> covalent compound (usually)
What are three common compounds?
Compounds
| compound name | compound formula | elements present |
|---|---|---|
| carbon dioxide | CO2 | carbon (C) and oxygen (O) |
| sodium chloride | NaCl | sodium (Na) and chlorine (Cl) |
| sodium hydroxide | NaOH | sodium (Na), oxygen (O) and hydrogen (H) |
| calcium chloride | CaCl2 | calcium (Ca) and chlorine (Cl) |
Is air an element or compound?
Air is a mixture but not compound. Its constituents can be separated. For example: oxygen, nitrogen etc.
How many compounds are there?
Globally, more than 350,000 chemical compounds (including mixtures of chemicals) have been registered for production and use. A compound can be converted to a different chemical substance by interaction with a second substance via a chemical reaction.
What is formula of simple compound?
The chemical formula of a compound is a symbolic representation of its chemical composition. ... For example, the chemical formula of water, which is H2O, suggests that two hydrogen atoms combine with one oxygen atom to form one molecule of water.
How do you describe a compound?
A compound is a substance formed when two or more chemical elements are chemically bonded together. In mixtures, the substances present are not chemically bonded together. ... The elements in any compound are always present in fixed ratios. Example 1: Pure water is a compound made from two elements - hydrogen and oxygen.
What is a biological compound?
Chemical Compounds in Living Things
The compounds found in living things are known as biochemical compounds. Biochemical compounds make up the cells and other structures of organisms and carry out life processes. Carbon is the basis of all biochemical compounds, so carbon is essential to life on Earth.
How the compounds are formed?
The answer is that compounds are formed when elements are joined and held together by strong forces called chemical bonds. ... Covalent bonds share electrons between atoms in order to fill their electron shells. In the compound, molecules are held together by the attraction between the nucleus and the shared electrons.
