Definition of Compound

Compound When two and more elements chemically combine in a fixed ratio by mass, the obtained product is known as a compound.

Also, compounds can define as substances consisting of 2 and more different types of elements in a fixed ratio of their atoms.

And when the elements combine, some individual property of the parts is lost, and the newly formed compound has new properties.

Chemical Formula

Compounds it represents by their chemical formula. And the chemical formula is the symbolic representation of the proportions of atoms that constitute a particular chemical compound.

Also, the chemical formula of water is H2O which shows two atoms of hydrogen and one atom of oxygen take combined to form one molecule of H2O.

And, the chemical formula for common salt is NaCl which shows one atom of sodium and one atom of chlorine combine the form one molecule of NaCl.

What are the Elements?

We can define elements as the species of atoms that take the same number of protons in their atomic nuclei.

Although an element’s atoms take the same number of protons, they can take different neutrons and hence different masses.

Also, isotope atoms of the same element that take different neutrons known as isotopes.

And Aa of now, there are 118 elements, of which the first 94 are naturally occurring while the remaining 24 are synthetic elements.

1. Types of Elements

The elements it arranges in a periodic table and split depending upon their groups as either metallic or non-metallic.

Also, metallic further is classified into primary group metals, transition metals, and f-block metals. And these are again further divided, depending upon their properties.

2. Examples of Elements

The elements exist in their simplest form and cannot break down further. So, features can live in the state of ions, atoms, isotopes, and molecules.
