write the name of the atom having the smallest size
What is the name of the atom having the smallest size?
Answer:
The atom with the smallest size is the hydrogen atom. Hydrogen consists of only one proton and one electron. It is the simplest, lightest, and smallest atom in the periodic table. The electron cloud of a hydrogen atom is the least spread out among all the elements, making it the smallest atom in terms of size. The small size of the hydrogen atom is due to its low atomic number and the lone electron occupying the first energy level.
