What is a number that can be used to indicate part of a whole?
A fraction is a number that represents part of a whole. It consists of a numerator (the top number) that represents how many parts are being considered, and a denominator (the bottom number) that represents the total number of parts in the whole.
What is the nearest whole number of atomic mass of potassium?
The nearest Whole number of atomic mass of potassium is 69
What is an element's atomic mass not listed as a whole number on the periodic table?
Few elements have isotopes. their atomic mass is not a whole number.
What number is the whole number found in the periodic table?
There are two numbers that are included in every element's block on every periodic table. The whole number, which can range from 1 - 118 is the atomic number of that element. The atomic number is the number of protons in the nuclei of the atoms of that element. The second number is the atomic weight and is never a whole number, except for the artificially prepared elements, and then it is a whole number written inside parentheses.There may be other numbers listed as well, depending on the periodic table. All periodic tables have a key as to what everything inside each block represents.
Why is the atomic mass of an element not a whole number while the atomic number is?
The atomic mass of an element is not a whole number because it includes the average mass of all isotopes of that element and their relative abundance. Isotopes have different masses due to varying numbers of neutrons, causing the atomic mass to be a weighted average. In contrast, the atomic number is a whole number representing the number of protons in an atom, which defines the element.
