An atom can't contain only part of a proton, so the number must always be a whole number

Atomic numbers represent the number of protons in an atom's nucleus, which are always whole numbers because protons are indivisible particles. Atomic numbers cannot be fractions or decimal numbers because they refer to a count of discrete, whole particles.

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.
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 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.
What element has the atomic number for 3.14?
There is no element with the atomic number 3.14. Atomic numbers are whole numbers that represent the number of protons in an atom's nucleus.
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.
Why atomic mass is always a whole number but atomic weight may be a decimal number?
Atomic mass is the total mass of protons and neutrons in an atom, which are whole numbers. Atomic weight, on the other hand, takes into account the abundance of different isotopes of an element, which can result in a weighted average that may be a decimal number.
Why is the relative atomic mass of chloride not a whole number?
Because relitive atomic masses are NEVER whole numbers.
Is the difference of 2 whole numbers always a whole number?
Yes, the difference of two whole numbers is always a whole number.
Do all isotopes have whole number atomic masses?
No, not all isotopes have whole number atomic masses. Isotopes are variations of an element with different numbers of neutrons, so their atomic masses can differ slightly from whole numbers due to the weighted average of the masses of the isotopes present in a natural sample.
Why are all atomic numbers whole numbers?
The atomic number is the number of protons.
Is the product of whole numbers always whole numbers?
Yes normally they produce whole numbers or integers
How often are whole numbers integers?
Always. By definition the Integers are the whole numbers; and the whole numbers are the integers.
Are whole numbers rational or irrational?
Whole numbers are always rational
