Flour, wheat ?
Wheat is not an element. Wheat is a compound of mixed elements.Stuff.
Yes it is.
Elements exist as isotopes in nature. So their atomic weight is not a whole number.
Actually group 1 is ALL elements and so is the whole periodic table.
The modern periodic law states that, The properties of the elements are the periodic function of there atomic number not atomic weights.
Elements also possess isotopes. So their average atomic mass is rarely whole number.
atomic number
A Periodic table The Periodic Table of the Elements.
By grouping the elements on the Periodic Table.
do you mean the why is the average atomic mass not a whole number? because if that is your question, then the answer is that each element has multipal isotopes and the mass you see on the periodic table is the average of all the isotopes together. So there has to be a decimal on the periodic table of elements
It is called the Periodic Table of Elements.
Because the masses of protons, neutrons and electrons are not whole numbers.
Few elements have isotopes. their atomic mass is not a whole number.
