Our Mission. The Office of Social Responsibility promotes social impact, recommends policy, develops internal and external socially responsible strategies, and ensures that Port activities are conducted within a framework of equity, inclusion and equal access.
Metal elements are usually good conductors of both electricity and heat. The dividing line between metals and non-metals is not hard and fast, thus the distinction between Post-transition metals and Metalloids is represented differently on different versions of the Periodic Table.etal elements are usually good conductors of both electricity and heat.

the metalloids or semimetals are located along the line between the metals and nonmetals in the periodic table the metalloids are boron silicon germanium arsenic antimony and tellurium polonium is often considered a metalloid tooproperties of the semimetals or metalloids the electronegativities and ionization energies of the metalloids are between those of the metals and nonmetals so the metalloids exhibit characteristics of both classessilicon for example possesses a metallic luster yet it is an inefficient conductor and is brittlehe reactivity of the metalloids depends on the element with which they are reacting for example boron acts as a nonmetal when reacting with sodium yet as a metal when reacting with fluorine the boiling points melting points and densities of the metalloids vary widely
