Why are mass numbers whole numbers?
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.
Why the mass numbers on the periodic table of elements are rarely whole numbers?
Elements also possess isotopes. So their average atomic mass is rarely whole number.
Atonic bladder type in tabes dorsalis?
atonic bladder
What is another name for atonic seizures?
Atonic seizures are also called "drop attacks"
Why is the mass numbers of isotopes exact whole numbers but the relative masses of most Atoms are not exact whole numbers?
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.
Why is the relative atomic mass of chloride not a whole number?
Because relitive atomic masses are NEVER whole numbers.
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.
The atomic mass of the elements are not whole value numbers because of the existence of?
D. Protons
How do isotopes differ and why is the atomic number of elements not a whole number?
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.
What is an unaccented syllable called?
Atonic
Why is the atomic mass of nobelium a whole number?
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.
What is the mass of mercury Hg?
The atomic mass of mercury (Hg) is approximately 200.59 grams per mole.
