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 else can I help you with?
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.
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.
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.
How to tell protons neutrons mass numbers atomic weights from periodic table?
Protons: Protons are the positively charged particles found in the nucleus of an atom. The number of protons in an atom is equal to its atomic number, which is listed on the periodic table. Neutrons: Neutrons are the neutral particles found in the nucleus of an atom. To determine the number of neutrons, subtract the atomic number (number of protons) from the mass number (rounded atomic weight). Mass number: The mass number of an atom is the sum of its protons and neutrons. It is usually rounded to the nearest whole number if not a whole number. Atomic weight: Atomic weight is the average mass of an element's isotopes, taking into account the abundance of each isotope in nature. It is listed on the periodic table underneath the element's symbol.
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.
Is fiber on the periodic table?
No, fiber is not an element found on the periodic table. Fiber is a type of carbohydrate that is found in plant-based foods like fruits, vegetables, and whole grains.
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 tells you the number of protons in the nucleus?
The atomic number of an element tells you the number of protons in the nucleus. It is the whole number found above the element symbol in the periodic table. Each element has a unique atomic number that corresponds to the number of protons in its nucleus.
Why is Tc on the periodic table bracketed and a whole number?
Tc, technetium, is bracketed on the periodic table because it is a synthetic element and not found naturally on Earth. The whole number represents its most stable isotope, which is artificially produced in nuclear reactors or particle accelerators.
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.
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 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.
How do you fine the mass number?
This is based on elements. You can use a periodic table. Mass number is equals to total of neutrons and protons.
How to tell protons neutrons mass numbers atomic weights from periodic table?
Protons: Protons are the positively charged particles found in the nucleus of an atom. The number of protons in an atom is equal to its atomic number, which is listed on the periodic table. Neutrons: Neutrons are the neutral particles found in the nucleus of an atom.

It is listed on the periodic table underneath the element's symbol.
Is the whole periodic table made out of elements?
Yes it is.
