No two different elements can have the same atomic number.
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.
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.)
All elements have protons and electrons. All but hydrogen have neutrons. All elements have isotopes which vary in neutrons but have the same amount of protons as the original element. Different elements never have the same amount of protons so scientists gave these elements their "atomic number" based on the amount of protons the element has. atomic number = amount of protons.
Isotopes differ from each other by having different numbers of neutrons but the same number of protons since they are only the same element if they have the same number of protons. Atomic numbers aren't whole because their mass is based of the mass of hydrogen and amu's (atomic mass units) and due to how elements are formed, minute amounts of mass are lost in order to form the nuclear bonds resulting in not whole numbers.
The same as its atomic number.
Elements have the same number of protons in each atomic nucleus.
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.
though your question is unclear, each element has its own atomic number. every sample of Sulfur (S) that exists has the atomic number of 16. No different elements share the same atomic number.
Atomic number is unique. It cannot be same for different elements.
They are the same
no. elements are defined by their atomic number (the number of protons).
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, each atomic number is unique to a single element.
Elements across a series have the same number of attributes or characteristics.
The number of protons in an elements nucleus is the same number at the atomic number.
isobars are elements with same mass numbers (Atomic Mass) and different atomic number (number of proton or electron)
