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.
Phosphorus is located in group 15 of the periodic table and has an atomic number equal to 15. This means that a neutral phosphorus atom has a total of 15 electrons. The ground state electron configuration for phosphorus is. P:1s22s22p63s23p3.
