Well obviously Hydrogen is the smallest atom because it only has one electron, this makes it unstable, but aside from that the period is 1.
The smallest part of an element that occurs naturally is an atom. Atoms are the basic units of matter and contain protons, neutrons, and electrons.
The smallest unit of life that can exist as a separate entity is a cell.
The atom that is smallest in size is the hydrogen atom.
The smallest atomic radius in period 5 belongs to the element with the highest nuclear charge, which is iodine (I) from Group 17. This is because as you move across a period, the nuclear charge increases, leading to stronger attraction for the electrons and a smaller atomic radius.
the atom with the least mass is the hydrogen atom
Neon
The smallest part of an element that occurs naturally is an atom. Atoms are the basic units of matter and contain protons, neutrons, and electrons.
Hydrogen is the smallest atom by mass. Helium, neon, fluorine and oxygen are smaller in size. Many calculations put the helium as the smallest atom. But a few other calculations put neon as the smallest atom!
The atom, which contain protons, neutrons and electrons; the protons and neutrons contain quarks and gluons.
The smallest atom is hydrogen.
The smallest unit of life that can exist as a separate entity is a cell.
The atom that is smallest in size is the hydrogen atom.
Atom is the smallest paricle for matters. Nucleus of it is posistioned at the center and it contains protons and neutrons. LaDy_caRoLi "christine carren alcantara"
