Einsteinium (Es) is only an artificial, unstable, radioactive metal member of the actinides family.
Seaborgium is considered a transition metal.
Yes. All elements from 1-20 are representative elements as they belong to a representative group (i.e. they aren't a transition metal).
Einsteinium is a synthetic element (Es) with atomic number 99. It is the seventh transuranic element, and a metallicactinide with +3 oxidation state.
Metal loud and nonmetal
Calcium is an alkaline earth metal, group 2A. Also may be defined as a representative element.
Any element that is in one of the representative elemenet groups is a representative element. A representative element group is any of the groups 1-2, 13-18, i.e. not a transition metal. So, a representative element is an element that isn't a transition metal.
no
Bromine is part of the representative elements
Seaborgium is considered a transition metal.
Yes. All elements from 1-20 are representative elements as they belong to a representative group (i.e. they aren't a transition metal).
Einsteinium is a synthetic element (Es) with atomic number 99. It is the seventh transuranic element, and a metallicactinide with +3 oxidation state.
Es un metal muy liviano con una densidad de 2700 kg/m³
Sodium is a representative element belonging to group 1 (s block element)
Oxygen is a representative element because it belongs to a group. Also, it is not situated in the transition metals area, and most importantly, it's not a metal!
Potassium Nitrate is a compound. The transition metals are found in groups 4-12 of the Periodic Table
Although mercury is very much a metal, it is not very representative of metals as it is liquid at room temperate while all others are solid.
Einsteinium. It has an atomic number of 99 and is represented by the symbol "Es".
