What is the isotope symbol for an element with 6 protons and a mass number of 15?
The isotope symbol for an element with 6 protons and a mass number of 15 is C-15.
What is the symbol and atomic number for an isotope with an mass number of 5 containing 10 neutrons?
The symbol for the isotope would be B and the atomic number would be 5, as the mass number is the sum of the protons and neutrons in the nucleus, so in this case: 5 protons + 10 neutrons = mass number 15.
How many neutrons and protons does a neutral atom of sodium with an atomic mass number of 23 have?
Every sodium atom has 11 protons, the atomic number of sodium. The isotope with mass number 23 has (23 - 11) or 12 neutrons, because the mass number of an isotope is defined as the sum of the numbers of protons and neutrons in the isotope.
How many protons neutrons and electrons are in phosphrous?
Phosphorus has 15 protons and 15 electrons in a neutral atom. The number of neutrons can vary in different isotopes of phosphorus, but the most common isotope has 16 neutrons.
How is nitrogen -15 isotope different from a nitrogen -9 isotope?
Nitrogen-15 has 15 protons and neutrons, while nitrogen-9 has only 9 protons and neutrons. Nitrogen-15 is a stable isotope, while nitrogen-9 is not stable and undergoes radioactive decay.
