No, look at any Periodic Table and you will see they are arranged in order of increasing mass.

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).
The elements in each____ have the same number of?
all the nuclei of all atoms belonging to one element will have the same atomic number, they may not necessarily have the same mass number
Do elements in the same group have the same atomic mass?
No.
Do all of the same elements have the same atomic number?
All isotopes of an element have the same atomic number because they have the same number of protons. However, they have a different mass because they have a different number of neutrons.
Do all of the elements have the same atomic number?
All isotopes of an element have the same atomic number because they have the same number of protons. However, they have a different mass because they have a different number of neutrons.
How atomic number better than atomic mass?
No two elements may have the same atomic number. But two elements may have same atomic mass. Hence atomic number is better than atomic mass.
What scientific instrument was used to discover that not all atoms of neon have the same mass?
The mass spectrometer was used to discover that not all atoms of neon have the same mass. This instrument separates and measures atoms based on their mass-to-charge ratio, allowing scientists to identify isotopes of elements like neon that have different masses.
What element has the Same atomic number but different number of neutrons?
Almost all the elements have different isotopes having same atomic no but different mass no or neutrons.
The elements in a are always combined in the same proportion by mass?
From many years this affirmation is not considered valid.
What is the weighted-average mass of all the known isotopes for an element?
The known weighted-averagemass of all the naturally occurring* isotopes for an element is the atomic mass of the element.____________________*This is not the same as "all the known isotopes", becausemost elements have known isotopes that are not naturally occurring.
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.
What two elements have the same atomic mass?
Two elements that have the same atomic mass are isotopes of the same element, such as carbon-12 and carbon-14, which are both forms of carbon but differ in the number of neutrons. However, if you're looking for different elements with nearly identical atomic masses, chlorine (atomic mass ~35.45) and argon (atomic mass ~39.95) have values that can sometimes be confused due to their proximity on the periodic table, but they are not equal. In general, elements do not share the exact same atomic mass.
