Question

what is compound?? explain​

Answer 1

1. ) In chemistry, a compound is a substance that results from a combination of two or more different chemical element s, in such a way that the atom s of the different elements are held together by chemical bonds that are difficult to break.

Compound Definition:

☞Compounds – Compounds are chemical substances made up of two or more elements that are chemically bound together in a fixed ratio.

☞Chemistry is the study of the structures, physical properties, and chemical properties of material substances. It is very important to understand that all gases, liquids and solids are not the same. All are different in terms of their composition. This is the reason why the classification of the matter is very important.

Classification of Matter :-

✏Elements

✏Compounds

✏Mixtures

What is a Compound?

☞When two or more elements chemically combine in a fixed ratio by mass, the obtained product is known as a compound. Compounds can be defined as substances consisting of 2 or more different types of elements in a fixed ratio of its atoms. When the elements combine, some individual property of the elements is lost and the newly formed compound has new properties.

☞Chemical Formula: Compounds are represented by their chemical formula. A chemical formula is a symbolic representation of the proportions of atoms that constitute a particular chemical compound.

☞The chemical formula of water is H2O which shows two atoms of hydrogen and one atom of oxygen have combined to form one molecule of H2O. The chemical formula for common salt is NaCl which shows one atom of sodium and one atom of chlorine combine to form one molecule of NaCl.

1. Types Of Compounds

☞Compounds can be classified into two types, molecular compounds and salts. In molecular compounds, the atom binds each other through covalent bonds. In salts, it is held together with ionic bonds. These are the two types of bonds out of which every compound is made of.

2. Example Of Compounds

☞Example of compounds includes water (H2O), Hydrogen Peroxide (H2O2), etc. You could see water’s chemical formula, it says it has 2 atoms of Hydrogen combined with 1 atom of oxygen and in hydrogen peroxide, it has 2 atoms of hydrogen and two atoms of oxygen.

Similarly, an example of salt would be the table salt (NaCl) which has 1 atom of sodium and one atom of chlorine.
