The Atomic Mass of an aluminum isotope with 13 protons and 15 neutrons is approximately 28 atomic mass units (amu). This is calculated by adding the number of protons (13) to the number of neutrons (15), giving a total of 28 nucleons. This isotope is known as aluminum-28.
13p/13p = Cacek diwb by 'p' HYence 13/13 = Cancel down by '13' Hence =1. The answer !!!!
It is 13p/1
1
The fraction 13p/1 pound = 13 p/100 p = 13/100.This fraction cannot be simplified.
p=10
-318-13p
13p+ You can look it up in the Periodic Table; it's the thirteenth one :) Eg. Lithium has three p+, so it's the third one (it also says that number somewhere at the top)

P2 + 13p - 30 = 0 Answer: p= -15, p = 2
