How many neutrons are in an isotope of lithium if it has an atomic mass of ten?

An isotope of lithium with an atomic mass of ten would have an atomic number of 3, meaning it has 3 protons. To find the number of neutrons, subtract the atomic number from the atomic mass: 10 (atomic mass) - 3 (atomic number) = 7 neutrons. Therefore, an isotope of lithium with an atomic mass of ten would have 7 neutrons.


What is the atomic mass of this atom 19p and 20n?

To calculate the atomic mass of an atom, you would add the number of protons and neutrons together. In this case, the atom has 19 protons and 20 neutrons, totaling 39 nucleons. The atomic mass of this atom would be approximately 39 atomic mass units (amu).


How do you calculate the atomic mas based on the number of protons and neutrons of an atom?

To calculate the atomic mass of an atom, you would add the number of protons and neutrons together. Protons and neutrons each have a mass of approximately 1 atomic mass unit (amu). The sum of the protons and neutrons will give you the atomic mass of the atom in atomic mass units.


An atom has 11 protons and 12 neutrons Its atomic mass is?

The atomic mass of an atom with 11 protons and 12 neutrons is calculated by adding the number of protons and neutrons together. In this case, the atomic mass would be 11 (protons) + 12 (neutrons) = 23 atomic mass units.


What does atomic mass do?

The atomic mass is equal to the number of protons plus neutrons. So if you know the atomic number then you can find out the number of neutrons Atomic # is the amount of Protons or Electrons Atomic Mass- Number of protons plus neutrons Atomic Mass-Atomic Number = Amount of neutrons

The correct symbol for the isotope of potassium with 22 neutrons is k 41 19?

The correct symbol for the isotope of potassium with 22 neutrons is K-41. The number after the element symbol represents the atomic mass, which is the sum of protons and neutrons in the nucleus. In this case, potassium has 19 protons and 22 neutrons, resulting in an atomic mass of 41.


How does the atomic mass help you find the neutrons?

Atomic mass = mass of protons + mass of neutrons.
