35,36 and 37. Chlorine has three stable isotopes chlorine-35, chlorine-36, chlorine 37 the most abundant of which are chlorine-35 and chlorine-37.
The mass number of an element is the sum of the number of protons and neutrons in the nucleus of an atom. For an atom with a mass number of 15.9994, it indicates the average atomic mass of an oxygen atom.
Mass number is the atomic mass of a particular isotope (apex chem 5.3)
the answer is gas
In order to calculate the number of neutrons, you subtract the atomic number (number of protons) from the atomic mass (rounded to the nearest whole number). Neutrons are important for stabilizing the atomic nucleus alongside protons.
Mass number: 14 Atomic/proton number: 7 If you look at the periodic table, the mass number is the top and the atomic number is the bottom number.

Isotopes are alternate forms of elements with differing neutron numbers. Isotopes have the same number of protons (and thus the same atomic number), but different numbers of neutrons, leading to variations in atomic mass. Some isotopes are stable, while others are radioactive and undergo decay.
The mass number of Am-241 is 241; each isotope has another mass number.
Atomic mass is the number of protons in an atom mass number is the number of protons plus neutrons in an atom the number of neutrons would equal the mass number minus the atomic number.
