Can two elements have 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.
Why is atomic number better than atomic mass for organizing the elements in the periodic table?
Atomic number is a unique number for each element. No two elements have the same atomic number. Atomic number is also the number of protons in the nuclei of the atoms of any given atom. Atomic mass, however, is the number of protons, neutrons and electrons. The number of neutrons can vary with different isotopes of the same element, this means that atomic mass can vary with different isotopes. So atomic number does not vary, but atomic mass does, so it is more logical to use atomic number to organize the elements. In addition, when the elements are arranged according to atomic number into seven rows and 18 columns, it becomes evident that there are certain trends that occur across the periods, and that elements in the same group have similar properties.
Does any element have the same atomic number as silicon?
No. Atomic numbers are characteristic of elements. Each element has its own unique atomic number. Only the 24 known isotopes of silicon will have the same atomic number because, only the atomic mass varies. Th element is still the same, i.e., silicon.
What do the molar masses of any two elements contain the same number of what?
Atoms have atomic weight not molar mass. Any atom-gram has 6,022 141 29(27)×1023 (this is the number of Avogadro) atoms.
How do you find out how many protons an atom has?
Every element has its own unique atomic number. The atomic number tells how many protons are in 1 atom of that element. Since no 2 elements have the same same atomic number, no 2 elements have the same number of protons. Basically, the atomic # is the same as the # of protons. For example: Aluminum= ''Al'' has an atomic # of 13, so it has 13 protons.
What atomic number would an isotope of uranium have?
The atomic number of uranium is 92; all the elements under uranium (under 92) were discovered.
What does the atomic number tell us about an atoms?
Atomic number, being a characteristic property (property that is diff. for each element), it identifies the element, For instance, Oxygen has an atomic number of 8, and it's the only one that has that atomic number, same with any other element, except that no other element has an atomic # of 8. No two elements can share an atomic number.
What does an atoms atomic number tell about the atom?
Atomic number, being a characteristic property (property that is diff. for each element), it identifies the element, For instance, Oxygen has an atomic number of 8, and it's the only one that has that atomic number, same with any other element, except that no other element has an atomic # of 8. No two elements can share an atomic number.
What are the other elements that have the atomic number of 18 like argon?
There are no such elements: the atomic number is a unique property of each particular element and is not shared with any other element.
What is meant by element?
Elements are pure substances inwhich all the atoms have the same number of protons (same atomic number) and thus have the same chemical properties. They cannot be separated by normal chemical means into any simpler substances.
Does atomic weight is same with atomic number?
Atomic weight is not the same as atomic number for any element except hydrogen; this is the only element that has a radioactively stable isotope with no neutrons.
The atomic number of potassium is?
Protons that are contained within any and all Atomic [Elemental] Nucleus / Nucleii.
