It could be Ca (though my tables give it a mass 40.08)
(or otherwise a relatively heavier isotope of a lighter element as 40K or 40Ar, but actually I couldn't find one with this mass)

Where on the periodic table are elements which the highest atomic mass?
The elements with the highest mass are on the bottom right of the periodic table.
Name two elements have the same mass numbers?
No elements have the same average mass, but some isotopes are the same mass as other elements, For example Carbon-13 (an isotope of carbon) has the same mass as nitrogen-13 (which is also an isotope of nitrogen).
Is the atomic mass used for the mass of an element which has isotopes?
Yes, it must be used as all elements have one or more isotopes and all elements have an atomic mass.
What is the atomic mass of this elements?
Gold is a meta element. Atomic Mass of it is 197.
What did Mendeleev think of the properties of the elements depended of?
Atomic Mass.
What 40115 divided by 669?
59.9626
How many elements make mass?
This question is a little ambiguous. If you mean 'how many elements have mass,' the answer is 'all elements have mass.' There are 117 known elements, and scientists theorize that there may be as many as 130 or more.
Mass number of first 20 elements?
Mass number is term used for isotopes, not for elements. And it is boring to list here all the isotopes of the first 20 elements.
How elements arrange?
On the periodic table, the elements are arranged by Atomic Mass. Helium and Hydrgen are at the way top of the table due to how they have the smallest amount of mass. The elements with the biggest mass are at the bottom.

Where on the periodic table are elements which the highest atomic mass?
The elements with the highest mass are on the bottom right of the periodic table.
What is the average of the mass numbers of an elements isotopes?
the Atomic Mass
When two elements chemically react the mass of the product is?
When two elements chemically react, the mass of the product is equal to the sum of the two masses of the two elements.
Name two elements have the same mass numbers?
No elements have the same average mass, but some isotopes are the same mass as other elements, For example Carbon-13 (an isotope of carbon) has the same mass as nitrogen-13 (which is also an isotope of nitrogen).
Is the atomic mass used for the mass of an element which has isotopes?
Yes, it must be used as all elements have one or more isotopes and all elements have an atomic mass.
Is there a difference between mass and atomic mass when dealing with elements?
Generally the term "atomic mass" is used for isotopes. For elements is preferred now "atomic weight".
What does the mass number?
By knowing mass number of the elements we can easily find out the number of neutrons presen in the nuclei.Physical properties of elements somewhat depends on mass number.
