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 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.
it's 31,because phosphorus has 16 neutron. So. 15+16=31
Number of neutrons = Atomic mass of an isotope - atomic number Atomic number of Cf is 98.
Cadmium-116 has 66 neutrons. This is determined by subtracting the atomic number (number of protons) from the atomic mass (sum of protons and neutrons): 116 (atomic mass) - 50 (atomic number) = 66 neutrons.
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.
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
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.

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
it's 31,because phosphorus has 16 neutron. So. 15+16=31
To find the number of neutrons simply subtract the atomic number from the atomic mass. In this case there are two neutrons.
Yttrium has 50 neutrons. To find the number of neutrons, subtract the atomic number (39) from the atomic mass (89): 89 - 39 = 50 neutrons.
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.
There are 62 neutrons in silver-107. Silver has an atomic number of 47, which corresponds to the number of protons in the nucleus. By subtracting the atomic number from the atomic mass, we can find the number of neutrons.
The atomic number (number of protons) of the element is needed to tell the number of neutrons. Mass number = atomic number + number of neutrons.
Number of neutrons = Atomic mass of an isotope - atomic number Atomic number of Cf is 98.
Cadmium-116 has 66 neutrons. This is determined by subtracting the atomic number (number of protons) from the atomic mass (sum of protons and neutrons): 116 (atomic mass) - 50 (atomic number) = 66 neutrons.
