What is the atomic mass number of an isotope that has an atomic number of 5 and includes 6 neutrons?

The atomic mass number is calculated by adding the number of protons and neutrons in the nucleus. In this case, the isotope with atomic number 5 and 6 neutrons would have an atomic mass number of 11 (5 protons + 6 neutrons = 11 atomic mass number).


The combined number of protons and neutrons?

The combined number of protons and neutrons is known as the mass number of an atom. It can be used to calculate the atomic mass by adding the total number of protons and neutrons in the nucleus of an atom.


What is the atomic mass number of an isotope that has an atomic number 5 and includes 6 neutrons?

The atomic mass number of an isotope is the sum of the number of protons and neutrons in the nucleus. In this case, atomic number 5 represents the number of protons, and adding the 6 neutrons gives an atomic mass number of 11 for this particular isotope.


What is delivered by adding the number of protons with the number of neutrons?

Adding the number of protons and neutrons in an atom will give you the atomic mass of the atom. The atomic mass is important for determining the overall mass of the atom and is an important factor in chemical reactions and nuclear stability.


What part of the nucleus determine the atomic mass for an element?

All parts of the nucleus, protons and neutrons if any, contribute to the atomic mass. The total number of protons and neutrons in an atom is its isotope mass number.


Adding the number of protons and the number of neutrons found in the nucleus of an atom yields the for isotope?

Adding the number of protons and neutrons in the nucleus of an atom gives the mass number of the isotope.


What is the atomic mass of a number that have 8 protons and 9 neutrons?

The atomic mass of an atom can be calculated by adding the number of protons and neutrons together. In this case, an atom with 8 protons and 9 neutrons would have an atomic mass of 17 atomic mass units (amu).


What information does the atomic mass of an elemt provide?

the number of protons and neutrons in an atom. Atomic mass is found by adding together the individual masses of the numbers of protons, neutrons, and electrons in the atom. --> Atomic Mass = protons + neutrons


Boron has an atomic mass of 11 and an atomic number of 5 how many neutrons must there be?

The mass of an atom is found by adding the number of the protons and neutrons. So, a boron atom with 5 protons and 6 neutrons would have an atomic mass of 11.


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.


How do you find the atomic mass by adding what?

Atomic mass = Mass of protons + Mass of neutrons


How do you determine the number of neutron?

Protons = Atomic Number Electrons = Atomic Number Neutrons = Atomic Mass - Atomic Number *A note on Atomic Mass* Atomic Mass is the sum of the number of protons and neutrons in an atom. Every time you remove or add a Proton/Electron or a Neutron, you change the mass by one. *A note on Protons and Electrons* The number of Protons and Electrons in an atom is always the same. Whenever you talk about adding/removing a proton or an electron, you are by default adding/removing one of the other as well.
