Mass number = no. of protons + neutrons Atomic number = no. of protons
Thus (mass number - atomic number) gives you no. of neutrons.
Therefore for phosphorus, the number of neutrons would be 16.
The Atomic Mass is the sum of neutrons and protons in the nucleus.
The atomic number of 15 means 15 protons, therefore the number of neutrons is 16
B
16
The atomic mass of phosphorous-31 is 30,97376163(20).
The number of protons is the atomic mass minus the number of neutrons; in this instance 32 - 17 or 15. An atomic number of 15 corresponds to the element phosphorus; therefore, the isotope is P-32.
The atomic mass is equal to the number of protons plus neutrons. So if you know the atomic number then you can find out the number of neutrons Atomic # is the amount of Protons or Electrons Atomic Mass- Number of protons plus neutrons Atomic Mass-Atomic Number = Amount of neutrons
The number of neutrons can be calculated if the atomic number and mass number of an element is known. The number of neutrons = Mass number - atomic number.
Atomic mass is the number of protons and neutrons in an atom.
18. Phosphorus has an atomic number of 15, therefore it has 15 protons. Phosphorus-33 has a total of 33 protons and neutron and therefore has 18 neutrons. Phosphorus-33 is a synthetic unstable isotope of P.
The atomic mass of phosphorous-31 is 30,97376163(20).
Have different atomic mass (have different numbers of neutrons)
Atomic mass is equal to the number of protons + neutrons present in the nuclide. The atomic number is defined as the number of protons in the nuclide. Therefore to find the number of neutrons use the formula: atomic mass = #protons + # neutrons solving for # of neutrons you get: # neutrons = atomic mass - # protons plug in the given values: #neutrons = 31 - 15 # neutrons = 16
The number of protons is the atomic mass minus the number of neutrons; in this instance 32 - 17 or 15. An atomic number of 15 corresponds to the element phosphorus; therefore, the isotope is P-32.
The most stable isotope of phosphorus is phosphorus-31. The atomic number of phosphorus is 15, so it has 15 protons. In a neutral atom, there will also be 15 electrons. The number of neutrons is mass number minus atomic number, which is 31-15, so the number of neutrons is 16.
the number of neutrons is mass
The atomic mass is equal to the number of protons plus neutrons. So if you know the atomic number then you can find out the number of neutrons Atomic # is the amount of Protons or Electrons Atomic Mass- Number of protons plus neutrons Atomic Mass-Atomic Number = Amount of neutrons
The number of protons and electrons are equal to the atomic number. For P, this is 15. The number of neutrons is the atomic mass minus the atomic number (31 - 15 = 16). So Phosporous has 15 electrons and protons, and 16 neutrons.
The Atomic Mass is equal to the number of protons plus neutrons. So if you know the atomic number then you can find out the number of neutrons Atomic # is the amount of Protons or Electrons Atomic Mass- Number of protons plus neutrons Atomic Mass-Atomic Number = Amount of neutrons
The number of neutrons can be calculated if the atomic number and mass number of an element is known. The number of neutrons = Mass number - atomic number.
