Solution for QID #95505: Unfortunately, there's no universal agreement on this, b | StudyHelpMe

Unfortunately, there's no universal agreement on this, but many versions of the Periodic Table will offer some guidance. Certainly, all of the elements in Groups 1-12 except hydrogen are considered metals. There's pretty good agreement that all of the elements in columns 17 and 18, plus elements ##"H, C, P, Se"##, and the elements to the right of them are non-metals. As you go down a Group, the elements become more metallic. Most chemists would say that ##"Al, Ga, In, Tl, Nh, Sn, Pb, Fl, Bi, Mc,"## and ##"Lv"## are metals. (From www.ptable.com) In between these broad groups are the and semiconductors, and different versions of the Periodic Table differ in how individual elements in this region are classified.
