Diagram of helium atom
WebFigure 7 shows the observed energy-level diagram for helium. The parity of the wave function is determined by inverting the coordinates of both electrons. Sign in to download full-size image FIGURE 7. The energy levels for the helium atom. WebWe know that the atomic number of helium is 2 and the atomic mass number is about 4. Neutron = 4 – 2 = 2. Therefore, a helium atom has two neutrons. Based on the atomic number, mass number, and neutron number of the element, three things can be considered. These are isotope, isobar, and isotone.

WebThe helium atom has two electrons and they can both fit into the Is orbital providing they have opposite spins. The other change to the diagram is that, with two electrons and electron repulsion a factor, the 2s orbital is now lower in energy than the three 2p orbitals, though these three are still degenerate. [Pg.94] WebThis means that for every electron there will be a proton, so you will be able to determine which element the atom is by comparing the electrons to the atomic number. For example, the above diagram has 2 electrons, so it is the element with atomic number 2, helium. Let’s look at an example.
