Describe selenium’s purpose as a trace element. Your email address will not be published. Consider an orbital diagram of the element selenium ([Ar] 4s^2 3d^10 4p^4). How many unpaired electrons does selenium have in its 4p orbital. The discovery of selenium was an important finding, but at the same time seemingly accidental. Unlike sulfur, selenium is a semiconductor, meaning that it conducts some electricity, but not as well as conductors. How many unpaired electrons does selenium have in its 4p orbital? For example, the orbital diagram for the first 18 atoms are shown below.
Part A For example, one allotrope of selenium can be seen as an amphorous (“without crystalline shape”) red powder. Photoconductivity is the idea that the electrical conductivity of selenium increases due to the presence of light or in other words, it becomes a better photoconductor as light intensity increases. Selenium (Se) has an atomic mass of 34.
