As the atomic number of nitrogen is 7, the most abundant isotope of this atmospheric gas must have 7 neutrons (14.007 - 7 = about 7), and this will make nitrogen-14 that isotope that is most abundant.
The isotope is named "carbon-12".
Carbon-14.
The mass number of the most common titanium isotope is 48.
Mercury is a metal element. Mass number of it is 201.
Subtract the atomic number from the mass number. Example Carbon-12 an isotope with a mas number of 12. Carbon has an atomic number of 6 therefore carbon-12 has 6 neutrons.
Carbon is a non metal element. Mass number of it is 12.
Carbon has a few isotopes. The most common naturally occurring isotope of it is C12. Mass number of it is 12.

The isotope is named "carbon-12".
The isotope is named "carbon-12".
Most helium has a mass number of 4. The rare 3He isotope has a mass number of 3. The mass number is the integer total of protons and neutrons for a given isotope. For example radioactive carbon-14 has a mass number of 14, while carbon-12 (the most common stable form) has a mass number of 12.
Carbon-14.
The mass number of the most common titanium isotope is 48.
Carbon-12
An isotope is member of an element of Mass Number differing from the average; for example, the most common isotope of Carbon is 12C (6 protons, 6 neutrons), where 13C and 14C would be less common (even unstable, radioactive) isotopes. So isotopes are varying forms of an element, differing in mass number.
13. The mass number is always the total number of protons and neutrons.
