Yes, Berillium is a medal, it is made with Be. Be is the formula
Berillium (Be atom number 4) is a metal, to be more precise it is the first of the alkaline earth metals, group 2 of the periodic table: Be, Mg, Ca, Sr, Ba, Ra
solid.
Berillium sulfide is BeS.
Beryllium flouride is the inorganic compound with the formula BeF
Metals in group 1A, 2A, 3A can form mono-, di- and trivalent positive ions respectively, and all are metals except Boron, which is a metalloid (between Carbon -a nonmetal- and Berillium -a metal- in period II).
Be is in the s block too. Li has one less proton than Be.
Aluminum Berillium Silicate...Includes Yellow & Red Beryl, Aquamarine, Emerald, Morganite....
This answer is correctedB stands for Boron, atom number 5 in group 13 (metalloid element) and has 3 valence electrons (like aluminum) so a cation would have 3+ charge.(Berillium (Be number 4, alkaline earth metal) has the 2+ion because it has 2 electrons on it's valence shell that it needs to share with a non-metal).Look at the periodic table group 2. group 13
Beryllium electron configuration is [He]2s2.
mercury is a metal. It is liquid at room temperature.
