Atoms of the same aomic number but different atomic wt. are called.....?

Answer 1

Isotopes. They occupy the same place in the periodic table (whose order is according to atomic number): "iso" (the same) "topos" (place).

Answer 2

Isotopes are forms of an element, therefore their nuclei have the same atomic number — the number of protons in the nucleus — but different mass numbers because they contain different numbers of neutrons.

The word isotope, meaning at the same place, comes from the fact that all isotopes of an element are located at the same place on the periodic table.

Collectively, the isotopes of the elements form the set of nuclides. A nuclide is a particular type of atomic nucleus, or more generally an agglomeration of protons and neutrons. Strictly speaking, it is more correct to say that an element such as fluorine consists of one stable nuclide rather than that it has one stable isotope.

In scientific nomenclature, isotopes (nuclides) are specified by the name of the particular element followed by a hyphen and the number of nucleons (protons and neutrons) in the atomic nucleus (e.g. helium-3, carbon-12, carbon-14, iodine-131 and uranium-238). In symbolic form, the number of nucleons is denoted as a superscripted prefix to the chemical symbol (e.g. 3He, 12C, 14C, 131I and 238U).

Answer 5

Isotopes.

Answer 6

Isotopes. Jeezs very easy!

Answer 7

Nice way to waste your points, well , your answer should be "isotopes".
Make sure you spell it right, because spelling like "aomic" will land you into a mental asylum

some elements have numerous isotopes, some of which are unstable

Answer 9

isotopes
