mass numbers are whole numbers because the mass number is number of protons in an atom, plus the number of neutrons. you can only have a whole neutron and or proton, therefore, all mass numbers are whole numbers.
Whole numbers can be positive or negative numbers. Numbers are whole as long as they have no fractins or decimals with them.
No. Positive numbers can be whole numbers but they can also be decimal numbers and fractions. If a value is a whole number, it does not have a fraction or decimal part and it is not negative. Whole numbers are also called natural numbers or counting numbers.
No. All whole numbers are integers and all integers are whole numbers.
Some rational numbers are whole numbers, some are not. The set of whole numbers is a proper subset of rational numbers.
Yes. ...-3,-2,-1,0,1,2,3... are all whole numbers. Whole numbers are any numbers that aren't a fraction and that includes negative numbers.
correct
Elements also possess isotopes. So their average atomic mass is rarely whole number.
Relative atomic massisthe ratio of the averagemassofatomsof anelementto 1/12 of the mass of an atom ofcarbon-12. The mass number of an isotope is the sum of protons and neutrons in the atoms of the isotope.
Because relitive atomic masses are NEVER whole numbers.
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.
D. Protons
Isotopes differ from each other by having different numbers of neutrons but the same number of protons since they are only the same element if they have the same number of protons. Atomic numbers aren't whole because their mass is based of the mass of hydrogen and amu's (atomic mass units) and due to how elements are formed, minute amounts of mass are lost in order to form the nuclear bonds resulting in not whole numbers.
The atomic mass of nobelium reported as a whole number is usually the average atomic mass of its isotopes, taking into account the natural abundance of each isotope. Since this average is calculated from the weighted average of the isotopes' masses, the result often appears as a whole number.
Mass numbers of elements are rarely whole numbers because they account for the isotopes of an element, which have different numbers of neutrons. The atomic mass listed on the periodic table is a weighted average of the masses of all naturally occurring isotopes, factoring in their relative abundances. As a result, this average often results in a non-integer value, reflecting the contributions of both stable and unstable isotopes.
The atomic mass of mercury (Hg) is approximately 200.59 grams per mole.
The atomic masses of most elements are not whole numbers because they take into account the average mass of all the isotopes of that element, which have different masses due to varying numbers of neutrons. This results in a weighted average that is not a whole number.
That is done mainly for basic chemistry. The normal practice is to take the weighted average of the various isotopes which, in almost all cases leads to numbers which are not whole.
