The element with the atomic number 15 is Phosphorus.
The atomic mass number of phosphorus is 31.
The atomic number is the number of protons, so 15.
Phosphorus is non metal element. Atomic number of it is 15.
The atomic number of an element refers to the number of protons in the nucleus of the atom of that element, and is unique to each element. The atomic weight is the weight of an atom of the element compared with the weight of a single proton, and consists of number of protons and neutrons in the nucleus of the atom of that element, and different atoms of the same element can have different numbers of neutrons, and therefore more than one atomic weight: it is usually given as an average. the atomic number on an element is simply the number of protons and electrons in the element. however, it is not the total number of them.
it's 31,because phosphorus has 16 neutron. So. 15+16=31
Phosphorus is a non metal. atomic number of it is 15.
an isotope of phosophorus(atomic number 15), with an extra neutron(creating a mass of 15+16+31
Phosphorus is a non meta element. Atomic Mass of it is 31. Atomic number of it is 15.
The element with an atomic mass of 30.97 is phosphorus. It has an atomic number of 15, meaning it has 15 protons in its nucleus. Phosphorus is a nonmetallic element commonly found in compounds such as phosphates.
i dont know if u what u meant but here's this Atomic Number: 15 Atomic Mass: 30.97376
The atomic mass of an element is the sum of the number of protons and neutrons in the nucleus of an atom. In this case, the element has 7 protons and 8 neutrons, so the atomic mass would be 7 + 8 = 15 atomic mass units.
The atomic mass number of phosphorus is 31.
The number of protons is the atomic mass minus the number of neutrons; in this instance 32 - 17 or 15. An atomic number of 15 corresponds to the element phosphorus; therefore, the isotope is P-32.
The atomic number is the number of protons, so 15.
Nitrogen is a non metal element. Atomic mass of it is 14.
why would I know this sit would not give me the answer :[
The atomic number is 7. The mass number is 15. The atomic mass is 15,000 108 898 2(7).
