We get the word 'allegory' from the Latin word 'allegoria ,' taken from the Greek word for 'veiled language.' Think of an allegory as an umbrella term for stories with deeper meaning-stories that are more than stories. Some allegories are very heavily veiled and might require an English professor to explain them to you.
A neutral phosphorus atom has 15 electrons. Two electrons can go into the 1 s subshell, 2 can go into the 2 s subshell, and 6 can go into the 2 p subshell. That leaves 5 electrons. Of those 5 electrons, 2 can go into the 3 s subshell, and the remaining 3 electrons can go into the 3 p subshell.
There are different ideas of what an electron is. One idea syas that an electron is part of an atom. Depending on the kind of atom, an atom can have 1 to 103 electrons. Each electron is extremely tiny. The mass (weight) of an electron is approximately equal to 1/1836 that of a hydrogen atom, which has one electron and one proton, so an electron is 1/1836th the size of a proton. Electrons carry a small electronically negative charge. In this model, electrons are in constant motion around the center of the atom.
