What is row 13 on the periodic table?
What is row 13 on the periodic table?
boron group element, any of the six chemical elements constituting Group 13 (IIIa) of the periodic table. The elements are boron (B), aluminum (Al), gallium (Ga), indium (In), thallium (Tl), and nihonium (Nh).
Is group 13 representative elements?
The elements in groups 1, 2, and 13 to 18 are called representative elements.
What type of element is ruthenium?
platinum metals
ruthenium (Ru), chemical element, one of the platinum metals of Groups 8–10 (VIIIb), Periods 5 and 6, of the periodic table, used as an alloying agent to harden platinum and palladium. Silver-gray ruthenium metal looks like platinum but is rarer, harder, and more brittle.
What family does thulium belong to?

Is group 13 A metal?
The boron family contains elements in group 13 of the periodic talbe and include the semi-metal boron (B) and the metals aluminum (Al), gallium (Ga), indium (In), and thallium (Tl).
What is the valence of group 13?
All group 13 elements have ns2np1 valence electron configurations, and all tend to lose their three valence electrons to form compounds in the +3 oxidation state.
Are groups 13-18 metals?
Group 18 elements are called noble gases. Groups 1, 2, and 13-18 are the representative elements (or main-group elements). Groups 3-12 are called the transition metals. The two rows at the bottom of the table are called inner transition metals.
What is Group 13-18 on the periodic table?
p-block elements
Groups 13-18 termed p-block elements. Main group elements in the first two rows of the table are called typical elements. The first row of the f-block elements are called lanthanoids (or, less desirably, lanthanides.
Is ruthenium a noble metal?
noble metal, any of several metallic chemical elements that have outstanding resistance to oxidation, even at high temperatures; the grouping is not strictly defined but usually is considered to include rhenium, ruthenium, rhodium, palladium, silver, osmium, iridium, platinum, and gold; i.e., the metals of groups VIIb.
What type of element is thulium?
lanthanide element
Thulium is a lanthanide element, it has a bright silvery-gray luster and can be cut by a knife. It is the least abundant of the rare earths and its metal is easy to work.
Is thulium a metal or nonmetal or metalloid?
metal
Thulium is a bright, soft, malleable, silvery-gray metal. It is a rare earth metal and is one of the least abundant.
