There are 15 protons in 31P. All isotopes and ions of the same elements will have the same number of protons regardless of the difference in the number of neutrons or electrons. So the information about which isotope is (by saying P-31) is unneeded.

How many protons and neutrons doe an atom contain?
Each atom has a unique combination of protons, neutrons, and electrons.
How many protons would 6 atoms of uranium contain?
One Uranium atom contains 92 protons as its atom number is 92. Therefore, 6 atoms contain 6*92=552 protons.
If the atomic mass of an atom is 48 and the atom contains 20 protons how many neutrons does the atom contain?
28. Atomic mass - Atomic # (same as the number of protons) = number of neutrons
How many protons do each of its atoms contain?
Each of whats atoms contain? Your question is non sense. Every type of atom has a different number of protons
How many protons does a neutural atom of chlorine have?
An atom of chlorine has 17 protons.
How many protons and neutrons doe an atom contain?
Each atom has a unique combination of protons, neutrons, and electrons.
How many protons does the nucleus of a silicon atom contain?
14
How many protons does an atom with the atomic number 50 and mass number of 125 contain?
This would contain 50 protons.
How many protons would 6 atoms of uranium contain?
One Uranium atom contains 92 protons as its atom number is 92. Therefore, 6 atoms contain 6*92=552 protons.

Atomic number of Al is 13. It contains 13 protons.
How many protons contain if the helium atom contains 2 electrons?
2
If a neutral atom contains 18 protons how many electrons does it contain?
18
How many protons does an aluminum atom contain?
The atomic number of aluminium is 13. So there are 13 protons in aluminium.

28. Atomic mass - Atomic # (same as the number of protons) = number of neutrons
How many protons do each of its atoms contain?
Each of whats atoms contain? Your question is non sense. Every type of atom has a different number of protons
How many protons does the second type of boron atom contain?
5. If it is more or less than 5 protons then it is not boron.
If the atomic mass of an atom is 38 and the atom contains 15 protons how many neutrons does the atom contain?
Protons and neutrons each have an atomic mass of 1 So, 38-15=23 Neutrons
