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.

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.
Why don't the elements on the periodic table have a whole number as their atomic weight?
Elements exist as isotopes in nature. So their atomic weight is not a whole number.
Why is the atomic mass of sulfur listed on the periodic table not a whole number?
The atomic mass given on the periodic table is a weighted average of all the isotopes, weighted by abundance of each isotope
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.
Does tungsten have a high or low atomic number?
Tungsten (W) has an atomic number of 74. This number is high compared to the whole Periodic Table. There are only 18 more natural elements with a higher number.
How do you find the atomic mass and the atomic number?
The atomic number is the whole # on the periodic table or the # of protons in an atom. The atomic mass is the # that is not the whole # on the periodic table, or you can multiply the mass of the isotope by its abundance and add the answers together.

How do you find nuetrons in a periodic table?
To find the number of neutrons in an atom, round the mass number to the nearest whole number and subtract the atomic number.
Does tungsten have a high or low atomic number?
Tungsten (W) has an atomic number of 74. This number is high compared to the whole Periodic Table. There are only 18 more natural elements with a higher number.
Is the whole periodic table made out of elements?
Yes it is.
Why elements don't have whole numbers?
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
What is the only element in the periodic table of group 1?
Actually group 1 is ALL elements and so is the whole periodic table.
Which number in an element box on the periodic table is the atomic number?
The atomic number is the whole number indicating the number of protons. It is usually directly above or below the element symbol.
Is Chloroform CHCI3 on the periodic table of elements?
Chloroform is CHCl3 (with a lowercase L), not CHCI3. CHCl3 is a compound. Made up of elements. There for C (carbon) H (hydrogen) and Cl (chlorine) are found on the periodic table of elements but not the whole compound.
