Why are atomic numbers listed as whole numbers?
Atomic numbers are whole numbers because they represent the number of protons in an atom's nucleus, which is a fundamental property of an element. Protons have a positive charge, and each element has a unique number of protons. Consequently, atomic numbers are always listed as whole numbers in the periodic table to reflect this inherent characteristic.
Why the atomic mass numbers listed for elements on the Periodic Table are not whole numbers.?
Why are atomic masses of elements not generally whole numbers? The atomic masses listed on the periodic table are a weighted AVERAGE of an element'sisotopes. ... An element's atomic number is the number of protons in its nucleus. Number of protons specifies atom type.
Are the atomic number and proton numbers always the same?
yes.
The atomic mass of the elements are not whole value numbers because of the existence of?
D. Protons
Why are all atomic numbers all whole numbers and most atomic mass number end with a decimals?
Atomic numbers represent the number of protons in an atom, which are whole numbers because protons are discrete particles. Atomic mass numbers, on the other hand, are weighted averages of the isotopes of an element, which can have fractional values due to the presence of isotopes with different masses and abundance.
