Radioisotopes

How Are They Made?What are isotopes?The isotopes of an element are all the atoms that have in their nucleus the number of protons (atomic number) corresponding to the chemical behavior of that element. However, the isotopes of a single element vary in the number of neutrons in their nuclei. Since they still have the same number of protons, all these isotopes of an element have identical chemical behavior. But since they have different numbers of neutrons, these isotopes of the same element may have...

Radioactive Element: Polonium

Polonium has more isotopes than any other element, all of which are radioactive. Polonium dissolves readily in dilute acids, but is only slightly soluble in alkalis. Weight for weight it is about 2.5 x 1011 times as toxic as hydro cyanic acid (HCN). Polonium has been found in tobacco as a contaminant and in uranium ores. Polonium is radioactive and present only in extremely low abundances in the environment. It is quite metallic in nature despite its location beneath oxygen in the periodic table...

Atomic Number & Mass Numbers

follows.  Review: 1. An element's or isotope's atomic number tells how many protons are in its atoms. 2. An element's or isotope's mass number tells how many protons and neutrons in its atoms. ISOTOPES After reading this section you will be able to do the following: * Define an isotope and explain how it is different than an element. The other particle in the nucleus of an atom is the neutron. The neutron has no electrical charge and is said to be neutral. Like protons, all neutrons...

most elements have isoptops

Most elements have isotopes. For stable isotopes, an interesting plot arises when the number of neutrons is plotted versus the number of protons. Because the plot shows only the stable isotopes, this graph is often called the Nuclear Belt of Stability. The plot indicates that lighter nuclides (isotopes) are most stable when the neutron/proton ratio is 1/1. This is the case with any nucleus that has up to 20 protons. As the atomic number increases beyond 20, a different trend becomes apparent. In...

versa. 2. Isotopes: atoms that have the same atomic number, but different mass number. (Same number of protons but different number neutrons.) 3. Mass and charge influence the degree of deflection in the magnetic fields Mass+ deflection-(65cu+<63cu+) charge+ deflection+ (63cu2+>63cu+) 4. The MS provides us: number of isotopes, relative isotopic mass (Ir) of each isotope, relative abundance. 5.

IsotopesIsotopes are atoms of the same element with the same proton number but with different neutron number. ❖ These atoms may have slight differences in physical and nuclear properties but have identical chemical properties. ❖ Proton number determines what element it is but neutron number can vary in a given element.
