Detailed explanation-1: -An atom is the smallest particle of an element, having the same chemical properties as the bulk element.
Detailed explanation-2: -Thus, helium is the smallest element, and francium is the largest. From top to bottom in a group, orbitals corresponding to higher values of the principal quantum number (n) are being added, which are on average further away from the nucleus, thus causing the size of the atom to increase.
Detailed explanation-3: -Molecule is the smallest particle of a substance that can exist independently. Molecule retains all the chemical properties of an element.
Detailed explanation-4: -Atoms-Smallest Unit of Matter.
Detailed explanation-5: -An atom is the smallest component of an element that retains all of the chemical properties of that element. is a negatively charged particle that travels in the space around the nucleus.
