Potassium
There is only one metal which is liquid at room temperature and that is Mercury (symbol Hg).
As 'pt' it is neither an element nor a compound. If you mean 'Pt' ( Platinum) , then it is an elementasl metal , found in the Periodic Table. NB For elemental symbols , a one letter symbol is ALWAYS a CAPITAL letter. For a two letter symbol , the first letter is always a CAPITAL letter and the second letter is small/lower case. This is the recognosed international standard. Hence 'pt' does not exist , but 'Pt' is platinum.
Group ONE - this group is called the Alkali metal group
The heaviest element with a one letter atomic symbol is uranium (symbol: U).
Bromine is an element, one of the halogens. Its chemical symbol is Br.
Potassium is a reactive metal, an alkali metal, placed in the group 1 of the periodic table, is soft, has a natural radioactive isotope, easily react with water and halogens, etc. The symbol is K.
Oh, dude, that's like a brain teaser or something. So, like, the element that fits that description is copper (Cu). Its symbol starts with a different letter from the first one in its name. So, yeah, copper is the odd one out in that group.
Group 1 will be more reactive than group 13 elements
a letter or symbol that stands for one or more numbers is a
Salts as a group do but other compounds do not.
Yes, the chemical symbol of an element is typically found in the periodic table, where elements are organized into groups based on their similar properties. Each element's chemical symbol is a one- or two-letter abbreviation derived from its name, often in Latin or Greek. These symbols help in identifying and differentiating elements within a group.
The group of one semi-metal and four metals can be found in Group 14 of the periodic table, which consists of carbon (semi-metal), silicon, germanium, tin, and lead (metals). These elements share similar chemical properties due to their arrangement in the same group.
