1919: British physicist Francis Aston (1852–1908) discovered a large number of atomic isotopes using mass spectrometry. 1938: German physicists Otto Hahn (1879–1978) and Fritz Strassmann (1902–1980) achieved the first nuclear fission (splitting up of heavy atoms to make lighter ones). 1945:...
Step-by-Step Solution:1. Definition of Isotopes: Isotopes are defined as atoms of the same element that have the same atomic number but different mass numbers. The atomic number represents the number of protons

1. Definition of Isotopes: Isotopes are variants of a particular chemical element that have the same number of protons (atomic number) but different numbers of neutrons. This results in different mass numbers for the isotopes of the same element. 2. Fundamental Particle of Difference: The fun...
Before one can understand isotopes, one must first understand atoms and what determines the element of an atom. In the nucleus of the atom, there are two particles. There is the positively charged proton and the neutrally charged neutron. Only the proton determines the atom's element....
When the elements shares the same atomic number but with a different mass number, it is known to be isotope of the original element. Some isotopes are radioactive also.Answer and Explanation: Bromine resides in group 17 of the periodic table. Its atomic symbol is Br. The atomic number ...
Isotopes are elements that have the same atomic number (which - as stated above - is what makes them the same element) but different Mass Numbers (A), due to different numbers of neutrons in their nuclei. For more about this see What is an isotope ?See also more words related to the...
Not only are atoms formed from smaller particles (protons and neutrons, which in turn are formed from quarks, and electrons), but they can also very much be split. Indeed, "splitting the atom" is a common phrase referring to nuclear fission power, and scarily the atomic bomb. There's a...
Elements are classified by the number of protons in the nucleus of the atom. However, there is no set rule for how many neutrons can be in the atom's nucleus. Because this number can vary, we classify the different, naturally occurring, variations of neutron quantities as isotopes of the ...
Hydrogen has three isotopes: protium, deuterium, and tritium. 6 Isomers Influence on properties. The boiling point of isobutane is lower than that of butane due to structural differences. 6 Isotopes Identified by atomic mass. Uranium-235 and Uranium-238 are isotopes used in nuclear reactors and ...
