The most common magnetic metal is iron. These metals are most reactive when in contact withair and water. Properties of the Post Transition metals: Physically, post-transition metals are soft (or brittle), have poor mechanical strength, and melting points lower than those of the transition metals; most also have boiling points lower than those of the transition metals. Rate 5 stars Rate 4 stars Rate 3 stars Rate 2 stars Rate 1 star . Example: Zn (s) + 2 HCl (aq) ZnCl 2 (aq) + H 2 ; 2. The elements in the 4 th row, groups 3-12, are collectively called first transition series, the 5 th row as the second transition series, and so on. Sometimes germanium and antimony are included, although they are normally considered metalloids.They normally have higher electronegativities than the transition metals. He organized the elements by atomic number, which is equal to the number of protons found in the nucleus of the element's atoms. They tend to be softer and conduct more poorly than the transition metals. Most are soft or brittle, with poor mechanical strength, and have melting points lower than the transition metals. The term dates back to 1921, when English chemist Charles Bury referred to a transition series of elements on the periodic table with an inner layer of electrons that was in transition between stable groups, going from a stable group of 8 to one of 18, or from a stable group of 18 to one of 32. In other words, the transition metals are elements: 21 (scandium) through 29 (copper) 39 (yttrium) through 47 (silver) 57 (lanthanum) through 79 (gold) 89 (actinium) through 112 (copernicium) - which includes the lanthanides and actinides Typically the elements of the post-transition metals include any metal in groups 13, 14, and 15 which are aluminum, gallium, indium, tin, thallium, lead, and bismuth.

The first main transition series begins with either scandium (symbol Sc, atomic number 21) or titanium (symbol Ti, atomic number 22) and ends with zinc (symbol Zn, atomic number 30). The cadmium (Cd), indium (In), and tin (Sn) are in the fifth row. Usually included in this category are Gallium, Indium, Thallium, Tin, Lead and Bismuth. Which elements are counted as post-transition metals depends, in periodic table terms, on where the transition metals are taken to end and where the metalloids or Nonmetals are taken to start. The transition elements are located in groups IB to VIIIB of the periodic table. They form a bridge between the chemically active metals of s-block elements and the less active elements of Groups 13 and 14. They are the alkali metals, alkali earth metals, transition metals, post-transition metals, metalloids, nonmetals, halogens, noble gases, lanthanides, and actinides. According to some chemists, the d-block elements are known as transition elements. The transition metals in the periodic tableinclude the 31 chemical elements of group 3 to group 11. Heavy metals periodic table Heavy metals are those metals which have higher densities or higher atomic mass. The elements in Group 1A are the alkali metals. [n 3] in the 1950s, most inorganic chemistry textbooks defined transition elements as finishing at group 10 ( nickel, palladium and platinum ), therefore excluding group 11 ( copper, silver and gold ), Post-Transition Metal. .
