This decides the electron capacity of the shells. The K shell contains a 1s subshell hence it can …
Groups in the periodic table a Group 1 is composed of hydrogen (H) and the alkali metals. Elements of the group have one s-electron in the outer electron shell. Hydrogen is not considered to be an alkali metal as it is not a metal, though it is more analogous to them than any other group. This makes the group … Visa mer In chemistry, a group (also known as a family) is a column of elements in the periodic table of the chemical elements.
