Metalloids-- oid, of course, being like a metal, so it's similar to metals, but, again, the properties are in between those of a metal and a nonmetal. It is a soft, silvery-white alkali metal. This period contains the lanthanides, also known as the rare earths.Many lanthanides are known for their magnetic properties, such as neodymium.Many period 6 transition metals are very valuable, such as gold, however many period 6 other metals are incredibly toxic, such as thallium.Period 6 contains the last stable element, lead.All subsequent elements in the periodic Rubidium is the first element placed in period 5. The exception is hydrogen, which behaves as a nonmetal at room temperature and pressure and is found on the upper left corner of the periodic table.Under conditions of high pressure, hydrogen is predicted to behave as an alkali metal. a. with high melting points and boiling points. Two highly reactive elements in period 2 are the metal lithium and the . Under standard conditions, it is the lightest metal and the lightest solid element. There are multiple ways of grouping the elements, but they are commonly divided into metals, semimetals (metalloids), and nonmetals. an element that is shiny and that's a good electricity and heat conductor; it is also malleable and ductible. Examples of Nonmetal Elements. Which of these is a property of metals? The transition metals are good electrical conductors and are very malleable.
