Isotopes are atoms of the same element with the same number of protons and different number of neutrons.
<h3>What are isotopes?</h3>
Isotopes are any of two or more forms of an element where the atoms have the same number of protons, but a different number of neutrons within their nuclei.
As a result of this, atoms of isotopes will have the same atomic number but a different mass number.
Examples of isotopes are
- Carbon-12 and Carbon-14
- Nitrogen-14 and Nitrogen-15
Therefore, isotopes are atoms of the same element with the same number of protons and different number of neutrons.

The organisms which appeared on earth first was bacteria.
<u>Explanation:</u>
- The first-ever living organism on Earth was a bacteria known as cyanobacteria. It is believed by scientists that it first formed around 3 billion years ago.
- When the Earth was first formed, it was inhospitable for a long time until 3.8 billion years ago approximately, the core cooled down and the level of oxygen had risen. This, along with photosynthesis resulted in the formation of Cyanobacteria.
- These organisms were capable of carrying out the process of photosynthesis by which they prepared their food. These were known as common ancestors. All the living organisms thereafter are known to be their descendants.
