What is the defined atomic mass in amu of this isotope?
12 amu
Why can an atom have the same number of neutrons and still be an isotope?
an isotope is defined by an atom with the same number of protons, but a different number of neutrons
What is the difference between a nuclide and an isotope?
An isotope is an element that has the same number of protons and a different number of neutrons, whereas a nuclide is a specifically defined isotope. Quite literally, they refer to the exact same atom, but the difference lies in the definition. Nuclides are defined by many different aspects, such as half life, mode of decay, percent abundance, and so on. The Chart of the Nuclides is a very extensive reference for the characteristics of over 3000 different isotopes. The term isotope is merely a way of differentiating between an atom that is the same element (same number of protons) but has varying numbers 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 the atomic mass of an element and how is it determined?
The atomic mass of a radioactively stable element is defined as the mass, usually measured in grams, of Avogadro's Number of atoms of the element as obtained from natural sources on Earth. For most elements, this atomic mass will be an average, weighted by natural isotope percentages, of the individual isotopes of the atom that naturally occur, but some elements have only one naturally occurring non radioactive isotope. The scale of atomic masses is now established by defining the mass of a carbon-12 isotope to be exactly 12. The atomic masses of other elements are defined by their mass ratios to a carbon-12 isotope.
What is the defined atomic mass in amu of this isotope?
12 amu
Why can an atom have the same number of neutrons and still be an isotope?
an isotope is defined by an atom with the same number of protons, but a different number of neutrons
What is the basic of time?
The second, defined as the time taken for a specific number of vibrations in a particular isotope of caesium.
If the number of neutrons in an atom is changed does the atom become a new element Why or why not?
No, it becomes a different isotope. An element is defined solely by the number of protons.
What is the basic unit of time is?
The second, defined as the time taken for a specific number of vibrations in a particular isotope of caesium.
How many protons does an atomic number of 6 and a mass number of 14 have?
The mass number of an isotope of an element is defined as the sum of the numbers of protons and neutrons in the nucleus of each atom of the isotope. The atomic number is defined as the number of protons only in the nucleus. Therefore, an atom with an atomic number of 6 has 6 protons in its nucleus.
Why do you think changing the number of neutrons does not create a new element?
Because an element is defined by it's atomic number. Which is defined by the number of protons found in atom. Adding a neutron creates an isotope of an element.

How is the term atomic number defined for a given atom or isotope?
Atomic Number is the number of protons that an atom has. The atomic number is different for each element.
What is the atomic mass of an element and how is it determined?
The atomic mass of a radioactively stable element is defined as the mass, usually measured in grams, of Avogadro's Number of atoms of the element as obtained from natural sources on Earth.

The atomic masses of other elements are defined by their mass ratios to a carbon-12 isotope.
What is the nuclear charge of an atom with an atomic mass of 35amu and atomic number of 17?
The mass number of an isotope of an element is defined as the sum of the numbers of protons and neutrons in the nucleus of each atom of the isotope. The atomic number is defined as the number of protons only in the nucleus. Therefore, an atom with an atomic number. Since neutrons have no electric charge, the nuclear charge of the specified atom is 17 amu.
