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.
The atomic number of lead is 82. That tells us that electrically neutral lead has 82 protons and 82 electrons. The three stable isotopes of lead are 206 Pb, 207 Pb, and 208â¦ Pb. These isotopes have 124, 125, and 126 neutrons per each atom, respectively.
