How To Make a Model of an Atom: This is a diagram of a helium atom, which has 2 protons, 2 neutrons, and 2 electrons. It's one of the simplest atoms to model.

Helium is a chemical element with atomic number 2 which means there are 2 protons in its nucleus.Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z. Now the helium atom is located at the far top-right side of the Periodic table. So according to the Periodic trends, the size of helium atom is the smallest in entire Periodic table. Now, let me explain the concept in another way. As we move from left to right in the Periodic table, the effective nuclear charge increases. Helium Atom, Approximate Methods 22nd April 2008 I. The Helium Atom and Variational Principle: Approximation Methods for Complex Atomic Systems The hydrogen atom wavefunctions and energies, we have seen, are deter-mined as a combination of the various quantum "dynamical" analogues of Helium is one of the "lightest" elements in the periodic table, second to hydrogen. However, hydrogen is an unstable element--the slightest increase in temperature could invariable cause a chain reaction of explosions! Helium, however, is a NOBLE GAS, which means it is a electrically satisfied (its electrons in its outermost orbital are all #umershah477 Chemistry, all Bise syllabus, structure of atom, atomic structure is described very breifly in very short time more concepts clear to you.
