Metals, Nonmetals, Metalloids

Postby GFolk_1D » Mon Oct 21, 2019 10:48 pm

Hi, does anyone know if we must memorize which elements are metals, nonmetals, and metalloids or will it be indicated on the periodic table given to us? If so, are there any tips to memorizing which is which? Thanks!

I don't know if it's required we memorize what's a metal, nonmetal, and metalloid, but I would recommend just knowing that boron, silicon, germanium, arsenic, antimony, tellurium, and polonium are metalloids. Everything to the right of those elements should be nonmetals and everything to the left should be metals (with the exception of hydrogen being a nonmetal).

When interpreting some chemical reactions it would be good to know which one is which because it tells you what types of bonds are formed or what their properties are. The periodic table is organized in a way where you would know which is a metal, nonmetal, or metalloid. The metalloids are kinds positioned weird but if you look at where they are you can see a step.

Metalloids have a characteristic diagonal pattern in the periodic table, so if you start with boron and follow a diagonal pattern until you reach a noble gas, specifically Og, and then add Sb and Ge which are the only ones left out, you can easily find out the metalloids. The elements to the right of the metalloids are generally nonmetals and the elements to the left of the metalloids are generally metals.

I do not think you have to memorize every element under the categories but a quick way to memorize the placements of the elements is by highlighting the parts on a physical periodic table, so you see which areas are under metal, metalloids, and nonmetal. Draw the diagonal line on the right side of the periodic table to separate the nonmetals.

A periodic table is given to us on each exam along with equations and constants. Therefore as long as u know when the line of metalloids are you will be able to figure out which questions are metals, metalloids, and nonmetals.
