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).
What is the unit of weight for elements?
The unit of weight for elements is typically measured in atomic mass units (amu) or grams. The atomic mass unit is defined as one twelfth of the mass of a carbon-12 atom.
Where on the periodic table are elements which the highest atomic mass?
Elements with the highest atomic mass can be found towards the bottom of the periodic table, typically in the bottom rows known as the actinide and lanthanide series. These elements include heavy elements such as uranium, thorium, and plutonium.
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.
Your eml rank is 40115 can you expect admission in iiser or iist?
i am NT sure dear............ my rank is e437.i am also in secure
What is the average of the mass numbers of an elements isotopes?
the Atomic Mass
Name two elements have the same mass numbers?

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.
How are the elements in the modern periodic arranged?
The elements are ordered by their mass number.
What is the unit of weight for elements?
The unit of weight for elements is typically measured in atomic mass units (amu) or grams. The atomic mass unit is defined as one twelfth of the mass of a carbon-12 atom.
In what order did Mendeleev arrange the elements in the first periodic table?
Mendeleev arranged the elements in the periodic table according to their atomic masses.
Where on the periodic table are elements which the highest atomic mass?
Elements with the highest atomic mass can be found towards the bottom of the periodic table, typically in the bottom rows known as the actinide and lanthanide series. These elements include heavy elements such as uranium, thorium, and plutonium.
Why did mendeleev chose to order the known elements by mass?
Mendeleev chose to order the known elements by mass because he observed that there was a pattern in the physical and chemical properties of elements when they were arranged by increasing atomic mass. This led him to develop the periodic table, where elements with similar properties were grouped together.
