roentgenium
Roentgenium is a chemical element in the periodic table that has the symbol Rg and atomic number 111, ...
Elements 110, 111, and 112 have been named. Element 110 is now called darmstadtium with the symbol Ds. Element 111 is now called roentgenium with the symbol Rg. Element 112 is now called copernicium with the symbol Cn.
Roentgenium (atomic number 111) - Rg is expected to be a transition metal, although sufficient tests haven't been conducted to prove this. It is at the bottom of the transition metals on the Periodic Table and in the Copper family. The synthetic element next to it (Copernicium) has been confirmed as a transition metal.
The Element with the Chemical Symbol of Rb is Rubidium. Rubidium is a soft, silver-white metallic elements of the alkali metal group. (A#-37 and AM-85.4678)
112th element is at current Ununbium. This will change soon though the German scientists who discovered the element have been allowed time to give it a more "personal" name before it is officially added to the periodic table.

Copernicium's periodic number is 112. It is is in period 7, group 12. Hg is above it, Rg is to the right of it, and Unutrium (temporary name) is to the left of it. (Depending on your periodic table, it may be slightly different.)

Transuranic elements: Np, Pu, Am, Cm, Bk, Cf, Es, Fm, Md, No, Lr, Rf, Db, Sg, Bh, Hs, Mt, Ds, Rg, Uub, Uut, Uuh, Uuq, Uup, Uuo.
The element is most likely located on the left side of the periodic table, in the "s-block" or "d-block," since these regions generally consist of metals with strong metallic properties. Additionally, elements in the "alkali metals" or "transition metals" groups are known to exhibit such characteristics.
Elements 110, 111, and 112 have been named. Element 110 is now called darmstadtium with the symbol Ds. Element 111 is now called roentgenium with the symbol Rg. Element 112 is now called copernicium with the symbol Cn.
Rutherfordium is a transactinoid.The members of the transactinoids family are: Rf, Db, Sg, Bh, Hs, Mt, Ds, Rg, Cn, Uut, Fl, Uup, Lv, Uus, Uuo. They are transition metals, period 7 of the periodic table of Mendeleev.
There is no element with the symbol Ng on the periodic table at the moment. Elements and there symbols starting with N are: N, Nitrogen; Ne, Neon; Na, Sodium; Ni, Nickel; Nb, Niobium; Nd, Neodymium and Np, Neptunium. Elements and there symbols ending with g are: Mg, Magnesium; Ag, Silver; Hg, Mercury; Sg, Seaborgium and Rg, Roentgenium.
"Rohm Gmbh" which essentially is Rohm Ltd. in German.
There are 118, but some tables still list only the most common, up to element 111, Rg (roentgenium)Scientists have discovered up to element 118, but four of the 118 have not been named except for their provisional designations (113 = ununtrium, 115 = ununpentium, 117 = ununseptium, 118= ununoctium).
The element provisionally named ununoctium, believed discovered in 2003, has atomic number 118 in Period 7, column 18, with an atomic weight of 294. Once confirmed, it will be given its permanent element name.
