Can atoms of two different elements have the same atomic number and could they have the same mass number?
The atomic number, or Proton number, defines which element it is. So by definition, two different elements must have a different atomic number, or else they'd be the same element.
Atomic Mass is the number of protons + neutrons in the element's nucleus. Since the number of neutrons in the nucleus can vary, even within a single element (as isotopes) it is possible to have one isotope of one element sharing an atomic mass with an isotope of another element.
What else can I help you with?
What has different atomic masses?
Different atoms and elements that have different number of protns, neutrons and electrons.Duh!
Atoms of different elements are what?
Atoms of different elements are characterized by the number of protons they contain in their nucleus, which determines the atomic number and identity of the element. The arrangement and number of electrons in the electron cloud surrounding the nucleus also vary among elements. Additionally, different elements have unique chemical properties based on how their atoms interact with one another.
Are all sample of elements are composed of atoms with same atomic mass?
No, different samples of an element can have varying atomic masses due to the presence of isotopes. Isotopes are atoms of the same element with different numbers of neutrons, leading to different atomic masses.
If there are 109 different elements there must be 109 different what?
If there are 109 different elements, there must be 109 different atomic numbers since each element has a unique atomic number that distinguishes it from other elements on the periodic table.
Are two atoms of different elements because they have close but different masses?
An element is made up of only one type of atom. Atoms are only different from each other due to their atomic number - which is the number of protons. Different elements may have different relative atomic masses, but it is the differing number of protons in each atom that determines which element it is.
A difference in the atomic number of atoms means the atoms are of same or diffierent elements?
Different atomic numbers represent different elements.
What do you know about two atoms if their atomic number are different?
the two atoms belong to two different elements
What makes atoms of different elements different from one another.?
The number of protons in the nuclei of their atoms. This is the atomic number of an element and each element has its own unique atomic number.
How are elements identified in terms of their atoms?
Elements are identified based on the number of protons in their atoms, which is known as the atomic number. Each element has a unique atomic number, allowing scientists to distinguish between different elements.
What has different atomic masses?
Different atoms and elements that have different number of protns, neutrons and electrons.Duh!
Can atoms of different elements have the same number of protons be from the same element?
No. Each type of atom (element) has its own unique number of protons, which is called the atomic number. Atoms of the same element will always have the same atomic number (number of protons). Atoms of different elements will never have the same atomic number (number of protons).
Do some atoms have more or fewer protons than will other atoms of the same element?
No. The atomic number of an element is determined by its number of protons. If two atoms have different numbers of protons, they have different atomic numbers and are different elements.

Can an atom of two different elements have the same mass number?
Yes. The mass number is basic to the different elements, even more useful than the atomic number. (Unless it is an isotope. Isotopes have a different amount of neutrons than the basic element atom which makes a difference in mass number too. So, a difference in mass numbers doesn't always mean it is a different element.)
Are all sample of elements are composed of atoms with same atomic mass?
No, different samples of an element can have varying atomic masses due to the presence of isotopes. Isotopes are atoms of the same element with different numbers of neutrons, leading to different atomic masses.
If there are 109 different elements there must be 109 different what?
If there are 109 different elements, there must be 109 different atomic numbers since each element has a unique atomic number that distinguishes it from other elements on the periodic table.
What does an elements atomic number?
The Atomic number tells you the number of protons in the nucleus of atoms of that element.
