is the Atomic Mass
Nucleon Number (total number of protons and neutrons)
false
Mass number = no. of protons + neutrons Atomic number = no. of protonsThus (mass number - atomic number) gives you no. of neutrons.Therefore for phosphorus, the number of neutrons would be 16.
The number of neutrons in an atom can be calculated by subtracting the atomic number from the atomic mass. In this case, an atomic mass of 16 and atomic number of 8 for oxygen means there are 8 neutrons (16 - 8 = 8).
Different isotopes of the same element have different numbers of neutrons but the same number of protons. The sum of the protons and neutrons is called the mass number. If you know the mass number and the number of protons (which is the atomic number), then you simply subtract the protons (or atomic number) from the mass number and the result is the number of neutrons. Example: Carbon-14 has a mass number of 14. Carbon's atomic number (and number of protons) is 6. So, 14 - 6 = 8 neutrons.
Nucleon Number (total number of protons and neutrons)
The number protons in an atom is called the atomic number (it is this number that tells us which element the atom is). The number of neutrons in an atom can change, but the term for the amount of neutrons is called an isotope. The number of protons and neutrons added together is called the atomic mass.
The number of protons, also called the atomic number.
The atomic mass
The combined number of protons and neutrons is known as the mass number of an atom. It can be used to calculate the atomic mass by adding the total number of protons and neutrons in the nucleus of an atom.
atomic number
false
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
Mass number = no. of protons + neutrons Atomic number = no. of protonsThus (mass number - atomic number) gives you no. of neutrons.Therefore for phosphorus, the number of neutrons would be 16.
The number of protons (or electrons) an atom has. To find out how many neutrons there are take the atomic number and subtract it from the Atomic Mass... (atomic mass)-(atomic number)= neutrons atomic number= #of protons (or #of electrons)
The number of neutrons in an atom can be calculated by subtracting the atomic number from the atomic mass. In this case, an atomic mass of 16 and atomic number of 8 for oxygen means there are 8 neutrons (16 - 8 = 8).
