Do copper isotopes have a whole atomic mass?
The isotopes of copper have the relative atomic masses of 63 and 65 and these are approximations. The exact values contain decimal figures.
What is an element's atomic mass not listed as a whole number on the periodic table?
Few elements have isotopes. their atomic mass is not a whole number.
Why don't the elements on the periodic table have a whole number as their atomic weight?
Elements exist as isotopes in nature. So their atomic weight is not a whole number.
Why is the atomic weight of bromine listed on the periodic table not a whole number?
Like almost all of the other elements bromine is a mixture of so-called isotopes. All of these isotopes are bromine and have almost identical chemical properties. They all have the same number of protons in the nuclei of their atoms. However, the numbers of neutrons in their nuclei vary. The atoms of some isotopes of bromine are a little heavier than the atoms of other isotopes. The atomic weight of bromine is the average weight of all of the isotopes of bromine, so it cannot be a whole number.
How can you identify an isotope?
Every individual atom is an isotope - it has a whole number of neutrons and a whole number of protons in its nucleus. The word isotope generally refers to a quantity of some material, where every atom in that portion has the same whole numbers as described above.
Why atomic mass is always a whole number but atomic weight may be a decimal number?
Atomic mass of isotopes is not a whole number.
Do copper isotopes have a whole atomic mass?
The isotopes of copper have the relative atomic masses of 63 and 65 and these are approximations. The exact values contain decimal figures.
Do all isotopes have whole number atomic masses?
The short answer is yes. The long answer is that isotopes have different numbers of neutrons than other isotopes of the same element, so when expressing the mass of an isotope, you don't take an average; you just add the number of neutrons and the number of protons. However, that number is not entirely accurate since the mass of a proton and a neutron are very slightly different. So, if you want to be very exact, then no, the mass of an isotope is not a whole number, but it is very, very close.
Can explain in terms of isotopes why the relative atomic mass of atomic number 17 is not a whole number?
Mass number is the average of all the naturally occurring isotopes of that element. When calculated, this average is not a whole number.
What is an element's atomic mass not listed as a whole number on the periodic table?
Few elements have isotopes. their atomic mass is not a whole number.
What whole number will an even number always divide by?
what whole number will 8 always divide by?
Why don't the elements on the periodic table have a whole number as their atomic weight?
Elements exist as isotopes in nature. So their atomic weight is not a whole number.
Is the difference of 2 whole numbers always a whole number?
Yes, the difference of two whole numbers is always a whole number.
Does the mass number of an element have to be a whole number?
Approximately, yes. But the mass number is an average of the masses of the isotopes of the element, weighted together according to their abundance. This averaging of different whole numbers results in the mass number not being a whole number.
Is Isotope mass a whole number?
yes,because in isotopes neutrons differ from normal element.
Is the difference of two whole number always a whole number?
yes
The product of two whole numbers is always whole number?
Yes always
