I'm currently studying grade 11 chemistry... And the periodic table of elements slightly confuses me.
I am having trouble understanding which are metalloids, and halogens. In the handout that my teacher gave me, it listed the following as metalloids: B, Si, Ge, As, Sb, Te, Po, and At. It also says the halogens are: F, Cl, Br and I.
On my school agenda, the included periodic table of elements lists the following as metalloids: B, Si, Ge, As, Sb, and Te. It says the halogens are: F, Cl, Br, I, and At.
On Wikipedia, it says these are metalloids: B, Si, Ge, As, Sb, Te and Po. It says the halogens are: F, Cl, Br, I and At.
Which is correct?!
:(
