How do you find atomic mass and mass number of isotope?
The atomic mass of an isotope is the weighted average of the masses of the naturally occurring isotopes of an element. It is found by multiplying the mass of each isotope by its natural abundance and summing these values. The mass number of an isotope is the total number of protons and neutrons in its nucleus and can be found by rounding the atomic mass to the nearest whole number.
How many neutrons in isotope?
It depends on what isotope you're talking about. To find the number of neutrons in a particular isotope, take the atomic mass and subtract the atomic number. For example, Na has a mass of roughly 23amu and 11 protons, so an Na-23 atom would have 12 neutrons.
What is the top number in an isotope?
An isotope is identified by atomic number (element number or name), by mass number, and by atomic weight. The mass numberfor an isotope is listed as a leading superscript such as 29Si, which in this example is silicon containing 14 protons and 15 neutrons (a rarer but stable isotope of the element). Similarly the atomic weight is indicated by a superscript such as U235 , an isotope of uranium having 92 protons and 143 neutrons.The actual atomic weight is often expressed as a decimal number corresponding to the mass of the atom in "atomic units", where a proton is about 1.0072, a neutron 1.0086, and an electron about .00055 atomic units.
The atomic number of carbon is 6 the atomic number of nitrogen is 7 the atomic number of oxygen is 8 name the isotope represented by the drawing?
The isotope represented by the drawing is Carbon-13. This isotope has 6 protons and 7 neutrons in its nucleus, giving it a total atomic mass of 13.
What is an isotope of strontium that has 52 neutrons?
Strontium-88 is an isotope of strontium that has 52 neutrons. It has an atomic number of 38, therefore the total number of neutrons (52) is obtained by subtracting the atomic number from the mass number.

Correct nuclear notation for isotope -15?
Be, B, C, N, O and F have an isotope with the mass 15. Example for nitrogen: 157N (15 is the atomic mass of the isotope, 7 is the atomic number of nitrogen). For other elements, of course, the atomic number is different.
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).
If you know the atomic number and the mass number of an isotope how could you figure out the number of neutrons in its nucleus.?
The mass number is the total number of protons plus neutrons in the nucleus. The atomic number is the total number of protons in the nucleus. So subtract the atomic number from the mass number and that will give you the total number of neutrons in the nucleus.
Sn isotope of oxygen has an atomic number of 8 and an atomic weight of 18. how many neutrons does it have?
The atomic number of an isotope is the number of protons it contains, whereas the mass number is the total mass of the nucleus, which is the combined number of protons and neutrons in the nucleus. To find the number of neutrons, you must therefore subtract the atomic number of the isotope from the mass number of the isotope.In the above example, the atomic number is 8 and the mass number is 18. This isotope is known as O18. The number of neutrons in the isotope is: Mass number - Atomic number = Number of neutrons18 - 8 = 10
What is the definition of isotope number?
The isotope number refers to the total number of protons and neutrons in the nucleus of an atom of a specific element. It is used to distinguish between different isotopes of an element based on their atomic mass.
Which number for an isotope is the neutron number?
The number of neutrons is never directly displayed.For a given isotope of an element, the "top number" (e.g. 14C or carbon-14) is the atomic mass number, the total of neutrons and protons. To find the number of neutrons, subtract the atomic number from the isotopes atomic mass number. Here, 14C will have 8 neutrons.
On the periodic table what is the name for 254?
There is no element 254. Elements are identified by their names and by their atomic numbers, the number of protons in the nucleus. Atomic numbers do not go up much past 110, if that far. However, element 99, Einsteinium, does have an atomic mass of 254, which describes the total number of protons and neutrons in its most common isotope. Perhaps that is what you mean.
