Elements are pure substances which are composed of only one type of atom. Compound are substances which are formed by two or more different types of elements that are united chemically in fixed proportions. There are nearly 118 elements (at present) of which nearly 94 occur naturally on Earth.

How are compounds formed?

Compounds occur when two or more atoms combine into a pure substance. These can be broken down into their constituent atoms. In chemical reactions the atoms of the reactants interact to form new substances. The reacting species are called reactants, and those produced are products.

Which of the following is a compound?

The correct answer is Water.

A compound forms whenever two or more atoms form chemical bonds with each other in a definite proportion. The chemical formula for water is H₂O, which means each molecule of water consists of one oxygen atom chemically bonded to two hydrogen atoms. Thus, water is a compound.

Which is not a compound?

Molecular hydrogen (H2), molecular oxygen (O2) and molecular nitrogen (N2) are not compounds because each is composed of a single element. Water (H2O), carbon dioxide (CO2) and methane (CH4) are compounds because each is made from more than one element. .

Is a compound a pure substance?

Compounds are pure substances made of two or more kinds of atoms bound together. Compounds can also be broken down into simpler substances.

Which of the following is not an example of compound?

Oxygen is NOT an example of a compound.

Oxygen has only one type of atom present in it, hence it is an element and not a compound.

Is water a compound or mixture?

Water is a compound because it is made up of water molecules. There is no such thing as water atoms. Water molecules are made of hydrogen and oxygen atoms, in the definite proportion of two hydrogens for one oxygen.

Are all compounds molecules?

All compounds are molecules. An example of a molecule is ozone. An example of a compound is table salt (sodium chloride). Molecules are simply a group of atoms which are bonded by a strong force.

How many types of compounds are there?

There are four kinds of compounds, depending on how the component atoms are held together: molecules held together by covalent bonds. ionic compounds held together by ionic bonds. intermetallic compounds held together by metallic bonds.

How do elements combine to form compounds?

Compounds form as a result of chemical reactions. The elements in compounds are held together by chemical bonds. A chemical bond is a force of attraction between atoms or ions that share or transfer valence electrons. Water is an example of a common chemical compound.
