Be, B, C, N, O and F have an isotope with the mass 15.
Example for nitrogen: 157N (15 is the Atomic Mass of the isotope, 7 is the atomic number of nitrogen). For other elements, of course, the atomic number is different.
The element is phosphorus and the isotope is 15P35
The isotope 7N15
There is no charge. Nitrogen-15 is an isotope, which refers to the number of neutrons. Neutrons do not have a charge.
13 protons means it must be aluminum (Al). 15 neutrons means its atomic mass will be 28. This is not aluminum's most abundant isotope, but it is still aluminum.
Phosphorus is a non metal with 15 protons, 15 electrons and 16 neutrons for its most stable isotope, 15P31.
P-33
Sulfur-31 is the isotope with 16 protons and 15 neutrons.
The element is phosphorus and the isotope is 15P35
Atom number 7 is Nitrogen, 157N , isotope 15 with mass number 15 The answer is N(15) isotope
15 hundredths in a decimal notation = 0.15
17P 15
The standard notation is 15
The isotope 7N15
15 = 15/1
15/1
The answer to 15 cubed in exponential notation is 15^3.
nitrogen-15
