What is compound explain with example?
A compound is a substance formed when two or more chemical elements are chemically bonded together. Example 1: Pure water is a compound made from two elements – hydrogen and oxygen. The ratio of hydrogen to oxygen in water is always 2:1. Each molecule of water contains two hydrogen atoms bonded to a single oxygen atom.
How do you name compounds with 3 elements?
If the compound contains three elements one of which is oxygen then the compound name will end in –ate or –ite, eg Calcium carbonate contains calcium, carbon and oxygen….Rule three.
| Prefix | Number of atoms |
|---|---|
| Tri- | Three |
| Tetra- | Four |
| Penta- | Five |
| Hexa- | Six |
How many types of compounds are there?
There are four types of compounds, depending on how the constituent atoms are held together: molecules held together by covalent bonds. ionic compounds held together by ionic bonds. intermetallic compounds held together by metallic bonds.

What is the difference between an element and a compound?
Compound vs. Element. Elements and compounds are pure chemical substances found in nature. The difference between an element and a compound is that an element is a substance made of same type of atoms, whereas a compound is made of different elements in definite proportions.
Which distinguishes elements from compounds?
Elements and compounds are pure chemical substances found in nature. The difference between an element and a compound is that an element is a substance made of same type of atoms , whereas a compound is made of different elements in definite proportions. Examples of elements include iron, copper, hydrogen and oxygen.
What are some examples of compounds and elements?
Examples of elements include iron, copper, hydrogen and oxygen. Examples of compounds include water ( H 2O ) and salt (Sodium Chloride – NaCl ) Elements are listed according to their atomic number on the Periodic Table . Among the 117 known elements, 94 are naturally occurring like carbon, oxygen, hydrogen etc.
What are the two types of elements and compounds?
Elements and compounds are the two types of pure substances. Examples of common elements include carbon, nitrogen and hydrogen. They consist of one type of atom and cannot break down into something else. Every pure carbon substance, for example, has the same particles in it. Compounds such as water, salt and sugar are also pure substances.
