In orbitals diagrams, the orbitals are shown as boxes, and the electrons in them as arrows pointing up or down. Each box represents one orbital, and each arrow indicates one electron. This is a way of showing the electron configuration … Read more
In the previous post, we talked about electron configurations, what they show, how to read, and how to write them based on energy levels and sublevels. As a reminder, electron configurations show the number and location of electrons in an … Read more
In the previous post, we discussed the nature of light and how the sunlight or the light from an ordinary light bulb (white light) contains a mixture of almost all the colors in the rainbow. This can be confirmed by … Read more
In these practice problems, we will go over examples of determining the wavelength, frequency, and energy of light, calculating the number of photons in a laser pulse based on the energy, understanding the correlation between the energy and wavelength and … Read more
Electron configurations tell us the number and location of electrons in an atom or an ion. Let’s first write a simple electron configuration and see what each letter and number indicate. For example, hydrogen has an electron configuration of 1s1. … Read more
