What are the atomic number (z) mass number (a) and symbols of the carbon isotope with 7 neutrons.
What is and how do I get the mass number?
Mass number is the sum of neutrons and protons. Carbon has six protons, so the mass number here is six plus seven= 13
The atomic number (Z) represents the number of protons in an atom's nucleus, and the mass number (A) represents the total number of protons and neutrons in the nucleus. To find the atomic number and mass number of a specific isotope of an element, you can refer to the element's periodic table.
In this case, we are looking for the carbon isotope with 7 neutrons. The atomic number of carbon is always 6 because it has 6 protons. To find the mass number, we need to add the number of protons (6) and neutrons (7).
So, the atomic number (Z) of this carbon isotope with 7 neutrons is 6, and the mass number (A) is 6 (protons) + 7 (neutrons) = 13.
The symbol for this carbon isotope can be written as C-13, where "C" represents carbon and "13" represents the mass number.
