The atomic number is the number of protons, so 15.
if there are 15 protons then the atomic number is 15. The element is Phosphorus.
Since the atomic number is by definition equal to the number of protons of that particular element, the answer is 15 protons in Phosphorus, 15P .
All phosphorus atoms have 15 protons (hence their atomic number of fifteen). Assuming the atom is neutral, it will also have an equal amount of electrons.
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
it's 31,because phosphorus has 16 neutron. So. 15+16=31
There are 15 protons and 16 neutrons in the phosphorus atom. The atomic number, which is at the top of the square, represent the number of protons. In a neutral atom, there are the same amount of protons as well as electrons so there are 15 protons and 12 electrons. You can find the number of neutrons by subtracting the atomic number from the atomic mass and round to the nearest whole number. In this case, the atomic number would be 15 and the atomic mass is 31. 31 minus 15 is 16 neutrons total.
7 protons , 8 neutrons and 7 electrons in the neutral atom. Nitrogen has an atomic number of 7. The atomic number is the number of protons in the nucleus. In the neutral atom this is also the number of electrons . The "15" in nitrogen-15 is the mass number, the total number of protons and neutrons in the nucleus. Taking 7 from 15 there are therefore 8 neutrons in nitrogen-15.
The atomic number of phosphorus is 15. So there are 15 protons
The atomic number of phosphorus is 15. So there are 15 protons in the nucleus of protons
15 (Its atomic number)
All phosphorus atoms have 15 protons (hence their atomic number of fifteen). Assuming the atom is neutral, it will also have an equal amount of electrons.
15, it the same as the atomic number.
15 protons. Atomic number determines the number of protons which the element has

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
it's 31,because phosphorus has 16 neutron. So. 15+16=31
Atomic number is the number of protons in an atom, not the number of atoms. The element with the atomic number 15 is phosphorus.
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.
Silicon-29 has 14 protons (atomic number), 14 electrons if the atom is neutral, and 15 neutrons (mass number - atomic number).
