Atomic number is the number of protons in an atom, not the number of atoms. The element with the atomic number 15 is phosphorus.
The atomic number is 7. The mass number is 15. The atomic mass is 15,000 108 898 2(7).
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.
Phosphorus is a non meta element. Atomic number of it is 15.
Atomic number for p is 15. atomic mass for p is 31.
Phosphorus is a none metal element. atomic number of it is 15.
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.
Atom of element phosphorus.if there are 15 protons then definitely the atoñc number is 15 and phosphorus seem to have atomic number 15
One phosphorus atom contains 15 protons and 15 electrons, giving it an atomic number of 15.
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 number is the number of protons, so 15.
Fifteen (15)
The element phosphorus has 15 atoms, as indicated by its atomic number on the periodic table.
Phosphorus is non metal element. Atomic number of it is 15.
The atomic number is 7. The mass number is 15. The atomic mass is 15,000 108 898 2(7).
Phosphorus is a non metal element. Atomic number of it is 15.
15 protons. Atomic number determines the number of protons which the element has
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.
