Question

Define Atom, lsotope​

Answer 1

In terms of chemistry, we can say that these twins are like isotopes of each other. Atoms and elements are made of protons, neutrons and electrons. ... These different versions of the same element are called isotopes. Isotopes are atoms with the same number of protons but that have a different number of neutrons.

$\huge\underline{Answer:}$

• Atom : An atom is the smallest constituent unit of ordinary matter that has the properties of a chemical element. Every solid, liquid, gas, and plasma is composed of neutral or ionized atoms. Atoms are extremely small; typical sizes are around 100 picometers.
• Isotope : Isotopes are variants of a particular chemical element which differ in neutron number, and consequently in nucleon number. All isotopes of a given element have the same number of protons but different numbers of neutrons in each atom.
