Elements are listed in the table by the structure of their atoms. This includes how many protons they have as well as how many electrons they have in their outer shell. From left to right and top to …

A photon on a hydrogen atom excited an electron from #n = 1# to make a transition to #n=3#. What is the wavelength (in run) pertaining to this transition and was the transition emitting or absorbing in …

What is the isotope symbol for an atom that contain 2 protons and 1 neutron? What is the isotope symbol for an atom that contain 82 protons and 125 neutrons? How do you represent the nucleus …

31 protons, 31 electrons and 40 neutrons. The atomic number of gallium is 31, which means it has 31 protons. If it is neutral the number of electrons is the same. The number of neutrons is the difference …

Geometric structure and Electron geometry depend on the central atom which here is Oxygen. In this case, oxygen has 2 unbonded pairs of electrons so due to the valence Electron shell pair repulsion, …
