∙ 13y agoThe atomic nass is not always a whole number, but the atomic number is because its the number of protons and neutrons.

∙ 6y agoBecause there is no such thing as a fraction of an electron.

∙ 14y agobecause you cant have a partial electron

Why are atomic numbers listed as whole numbers?
The atomic number is derived from how many protons are present in the nucleus of an atom. Becaue you cannot have a fraction of a proton present in an atom, atomic numbers must be non negative integers.
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 is the atomic mass of nobelium a whole number?
For elements with no stable isotopes (like Nobelium), the mass number of the isotope with the longest half-life is used. Mass numbers are whole numbers.
Why is the atomic number on the periodic tabe never a whole number?
The question is based on a complete lack of understanding as to what the atomic number is! They are always, without exception, whole numbers.
Why are atomic numbers listed as whole numbers?
The atomic number is derived from how many protons are present in the nucleus of an atom. Becaue you cannot have a fraction of a proton present in an atom, atomic numbers must be non negative integers.
What element has the atomic number for 3.14?
No element has this atomic number. All atomic numbers are whole numbers.
Why is the relative atomic mass of chloride not a whole number?
Because relitive atomic masses are NEVER whole numbers.
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.
Why are different whole numbers not always a whole number?
Different whole numbers are always whole numbers, but I suspect you meant to ask about the difference between whole numbers. You can subtract two whole numbers and get a negative result. Whole numbers can't be negative.
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.
Is the difference of 2 whole numbers always a whole number?
Yes, the difference of two whole numbers is always a whole number.
Is 40.08 the atomic number?
No. Atomic number is always a whole number. This would be the atomic mass.
Why are all atomic numbers whole numbers?
The atomic number is the number of protons.
Is the atomic mass of an element is always a whole number of atomic mass untis?
No.
Is the product of whole numbers always whole numbers?
Yes normally they produce whole numbers or integers
