Question

decribe the group in modern periodic table​

Answer 1

A group is any column on the periodic table. Elements in the same group usually have similar properties, because they have the same number of electrons in the outermost shell. There are eight main groups of elements and ten groups of transition metals:

Group 1: the alkali metals (lithium family)

Group 2: the alkaline earth metals(beryllium family)

Groups 3-12: the transition metals

Group 13: the triels (boron family)

Group 14: the tetrels (carbon family)

Group 15: the pnictogens (nitrogen family)

Group 16: the chalcogens (oxygen family)

Group 17: the halogens (fluorine family)

Group 18: the noble gases (helium/neonfamily)
