No, two elements cannot have the same atomic number. The atomic number of an element is determined by the number of protons in its nucleus, which is unique to each element. Therefore, elements with different atomic numbers will have different numbers of protons and thus different chemical properties.
When two elements have the same atomic number, it means they are isotopes of each other. Isotopes have the same number of protons but different numbers of neutrons in their nuclei. This results in subtle differences in their atomic mass and stability.
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).
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.)
No, because some elements have Isotopes, with the same Proton number but different Neutron numbers. Sometimes therefore, the neutron number can overlap with that of isotopes of other elements. For example, two of Helium's isotopes share neutron numbers with two of Hydrogen's isotopes. Deuterium has 1 neutron, and so does 3He, Tritium has 2 neutrons, and so does 4He. It is the number of protons which determines which element it is.
Number of protons
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.
When two elements have the same atomic number, it means they are isotopes of each other. Isotopes have the same number of protons but different numbers of neutrons in their nuclei. This results in subtle differences in their atomic mass and stability.
No two different elements will have the exact same atomic number. Each element has a unique number of protons in its nucleus, which determines its atomic number and distinguishes it from other elements.
No two elements will have the same atomic number because the atomic number of an element is determined by the number of protons in the nucleus of an atom. Since each element has a unique number of protons, each element will have a unique atomic number.
no that's not possible
No two elements have the same number of protons.
No. Elements are composed of atoms that have the same number of protons (atomic number) in their atomic nuclei. Compounds are composed of two or more elements that are chemically combined.
No. Elements are composed of atoms that have the same number of protons (atomic number) in their atomic nuclei. Compounds are composed of two or more elements that are chemically combined.
Atomic number
No, they have the same atomic mass, which is the number of protons plus the number of neutrons. No two elements have the same atomic number.
No two elements would have the same atomic number, so, nor atoms of different elements (in neutral state) would have the same number of electrons.
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).
