How many valence electrons are contained in the element represented 3115P?
Answer Details
The element represented by "31P15" is phosphorus (P), which has 15 electrons in total. To determine the number of valence electrons, which are the outermost electrons involved in chemical bonding, we look at the element's position on the periodic table. Phosphorus is in Group 15, so it has 5 valence electrons. This is because the number of valence electrons in elements in a particular group is equal to the group number. Therefore, phosphorus has 5 valence electrons.
