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 does the atomic mass describe?
the mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.
What is used to find the mass of an atom?
The mass of an atom is obtained dividing the atomic weight of an isotope by the Avogadro number.
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 number is written after the isotope when writing the name?
The atomic mass number of that isotope. So C14 has a molecular mass of 14 grams/mole U238, 238 grams/mole
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)
Is the sum of the numbers of protons and the number neutrons in an atom is the mass number?
It is the mass number for that particular form of the atom - that particular isotope. An element can exist as more than one isotope and the atom's mass number is the (weighted) average of the mass numbers of all its isotopes.
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 does the atomic mass describe?
the mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.
What is the name that has the number of 7 and the mass number of 15?
Atom number 7 is Nitrogen, 157N , isotope 15 with mass number 15 The answer is N(15) isotope
What is used to find the mass of an atom?
The mass of an atom is obtained dividing the atomic weight of an isotope by the Avogadro number.
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 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 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.
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
How many neurons are in an atom of platinum?
Each isotope has another number of neutrons.Number of neutrons = Mass number of an isotope – 78
