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

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.
Can you find out the number of electrons by adding protons and neutrons?
To find out the number of electrons in an element you must add the protons and neutrons and subtract that number with the atomic mass, this will determine the amount of electrons because the unknown element could be an isotope and have more than the normal amount of electrons of the non isotope element.
An isotope of xenon has an atomic number of 54 and contains 77 neutrons. What is the mass number of the xenon isotope?
The atomic number of an element is the number of protons in its nucleus. Always. The mass number of an atom is the number of protons plus the number of neutrons in it. And that means an isotope of element 54 (xenon) that has 77 neutrons in its nucleus has a mass number of 54 + 77 or 131, and you'll have an atom of 131Xe. A link can be found below.
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).
What is the isotope of atom?
An isotope atom of an element is one with the same number of protons in the nucleus (i.e the atomic number) but with a different number of neutrons giving it a different mass. Isotopes have the same chemistry because they have identical valence shells. An example is chlorine which is found in nature with two stable isotopes 35Cl with 18 neutrons and 37Cl with twenty. As 35 is around 75% and 37 25% in nature the atomic weight is 35.453.
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.
How many subatomic particles does krypton have?
Protons 36 Neutrons 48 (for the most stable isotope, Kr-84) Electrons 36
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.
Can you find out the number of electrons by adding protons and neutrons?
To find out the number of electrons in an element you must add the protons and neutrons and subtract that number with the atomic mass, this will determine the amount of electrons because the unknown element could be an isotope and have more than the normal amount of electrons of the non isotope element.

The atomic number of an element is the number of protons in its nucleus. Always. The mass number of an atom is the number of protons plus the number of neutrons in it. And that means an isotope of element 54 (xenon) that has 77 neutrons in its nucleus has a mass number of 54 + 77 or 131, and you'll have an atom of 131Xe. A link can be found below.
How many particles are found in the nucleus of a uranium atom?
how many particles are found in the nucleus of a uranium atom? 92 protons and x neutrons; the number of the neutrons is dependent of the isotope atomic mass. Also 92 electrons.
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).
What element has 38 protons and 58 neutrons?
The element with 38 protons is strontium (Sr). Adding 58 neutrons gives you a specific isotope of strontium, which would be Sr-96, as isotopes are defined by the total number of protons and neutrons in the nucleus.
What element has 16 protons and 15 neutrons?
The element is sulfur and the isotope is 16S31
The mass number of an atom is found by adding the?
The mass number of an atom is found by adding the number of protons and neutrons in its nucleus. It is an integer value that represents the total number of nucleons in the atom.
What atom has 23 protons and 29 nuetrons?
If it has 23 protons it has to be Vanadium no matter the number of neutrons. Deciding what element an atom is depends solely on the number of protons. However, the neutrons tell you which isotope of vanadium it is.
What is the isotope of atom?
An isotope atom of an element is one with the same number of protons in the nucleus (i.e the atomic number) but with a different number of neutrons giving it a different mass.
