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

How many neutrons does a phosphorus-32 atom have?
how many neutrons there are in a phosphorus atom? The normal isotope of phosphorus is P - 31, which has 15 protons and 16 neutrons. Unstable isotopes are P-32 and P-33 which have 17 and 18 neutrons respectively.
How many protons are in an atom which has an atomic number of 15?
it's 31,because phosphorus has 16 neutron. So. 15+16=31
How many neutrons in californium?
Number of neutrons = Atomic mass of an isotope - atomic number Atomic number of Cf is 98.
How many neutrons does a cesium 141 have?
The atomic number of cesium is 55. The number of neutrons is the isotope mass number minus atomic number, or in this instance 86 neutrons.
How many neutrons is in californium?
153 neutrons in the most stable isotope Number of neutrons = Atomic mass of an isotope - atomic number. Atomic mass of the most stable isotope of Cf is 251. Atomic number of Cf is 98.
How many protons and neutrons are in phosphorous-32?
Well phosphorous always has 15 protons and even in different isotopes of an element the proton (atomic) number will be the same..So even in phosphorous-32, there are 15 protons.. If it is phosphorous-32 then the total of the protons and the neutrons is 32.. 15 protons...So to get the number of neutrons do 32 minus 15 = 7 neutrons.. Just to note, the number of electrons is of course the same as the number of protons so it is 15
How many neutrons does the nucleus of the phosphorus 32 have?
Phosphorous-32 has 17 neutrons in its nucleus. You can work it out like this :- The atomic number for Phosphorous is 15 (that means it has 15 protons and 15 electrons). The + charged protons sit in the nucleus and are electrically balanced by the - charged electrons that orbit the nucleus. If you subtract the atomic number (15) from the atomic weight (32) this tells you how many neutrons there are accompanying the protons in the nucleus because the electrons essentially weigh nothing.
How many protons neutrons and electrons are found in phosphorous?
Phosphorus has an atomic no. of 15 and its atomic mass is 31.=we know,atomic no.=number of protons==also, atomic mass=no.of protons+no. of neutrons==this implies, 31=15+no. of neutrons= 31-15=no. of neutrons= 16=no. of neutrons==also,no. of protons=no, of electrons=so, total no. of protons=15total no. of electrons=15total no. of neutrons=16

How many protons are in an atom which has an atomic number of 15?
it's 31,because phosphorus has 16 neutron. So. 15+16=31
Atomic number of 2 and atomic mass of 4 how many neutrons?
To find the number of neutrons simply subtract the atomic number from the atomic mass. In this case there are two neutrons.
How many neutrons in californium?
Number of neutrons = Atomic mass of an isotope - atomic number Atomic number of Cf is 98.
How many neutrons dose hassium have?
Number of neutrons = Atomic mass of an isotope - Atomic number of the element The atomic number of hassium is 108; each isotope of an element has a different number of neutrons and a different atomic mass.
How many neutrons does a cesium 141 have?
The atomic number of cesium is 55. The number of neutrons is the isotope mass number minus atomic number, or in this instance 86 neutrons.
How many neutrons are does yttrium have with an atomic number of 39 and atomic mass of 89?
50 neutrons
How many neutrons are in an atom with the mass number being 186?
The atomic number (number of protons) of the element is needed to tell the number of neutrons. Mass number = atomic number + number of neutrons.
How many neutrons are in roentgenium?
Roentgenium-272 has 161 neutrons. Number of neutrons = Atomic mass of an isotope - Atomic number of the element The atomic number of roentgenium is 111, but Rg has many isotopes each with a different atomic mass and number of electrons.
