How many neutrons and protons does neutral atom of sodium with an atomic mass number of 23 have?
Every sodium atom has 11 protons, the atomic number of sodium. The isotope with mass number 23 has (23 - 11) or 12 neutrons, because the mass number of an isotope is defined as the sum of the numbers of protons and neutrons in the isotope.
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.
How many neutrons does an atom of flerovium have it its nucleus?
For each isotope of Fl the number of neutrons is different (the number of neutrons is between 170 and 175). Number of neutrons = Mass number of an Fl isotope - 114
How many neutrons are in meitnerium?
Number of neutrons = Atomic mass of an isotope - Atomic number of the element The atomic number of meitnerium is 109. Each isotope of an element has a different number of neutrons.
How is atomic mass number calculated?
There are a few ways to determine the mass number, depending on what information you have about the isotope: 1. The mass number is calculated as the sum of an isotope's protons and neutrons. 2. The name of an isotope generally includes the mass number. For instance, carbon-14 has a mass number of 14. 3. The atomic mass (aka isotope mass or atomic weight) rounded to the nearest whole number is the mass number.
How many neutrons does a technetium atom have?
For each isotope the number of neutrons is different. Number of neutrons = Mass number of an Tc isotope - 43
What does the number of neutrons determine?
they determine the atomic mass of the atom
What is the mass number of an isotope of this atom that has neutrons?
It is 3 because you have to add the neutrons and the protons.
How does the atomic number relate to the number of protons in an atom?
Atomic Mass (of an isotope) - number of protons (of an isotope) = number of neutrons (of an isotope)
What is the number of neutrons in the element sulfur?
The number of neutrons in an atom depends on the isotope. The most common sulfur isotope has 16. The average number of neutrons in an atom of sulfur is about 32.065.
What is the atom's mass number of an isotope that has an atom number of 5 and includes 6 neutrons?
The Atomic Mass is, basically, the sum of the protons (the "atomic number"), and the number of neutrons.
How many neutrons and protons does neutral atom of sodium with an atomic mass number of 23 have?
Every sodium atom has 11 protons, the atomic number of sodium. The isotope with mass number 23 has (23 - 11) or 12 neutrons, because the mass number of an isotope is defined as the sum of the numbers of protons and neutrons in the isotope.
What is mass number of an isotope of this atom that has 2 neutrons?
It is 3 because you have to add the neutrons and the protons.
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 defins the mass number of an isotope?
The mass number is the total weight of neutrons and protons in the nucleus of an atom.
What defines the mass number of isotope?
The mass number is the total weight of neutrons and protons in the nucleus of an atom.
What represents the number of protons and neutrons in an atom of uranium?
The number of protons is equal to the number of electrons and the atomic number. The number of neutrons is different for each isotope (number of neutrons = atomic mass of the isotope [or mass number] - number of protons).
