It stacks the elements in columns according to the number of valence electrons in an atom of the element. Valence electrons are those in the outermost shell of the atom and the ones that participate in reactions. The number of valence electrons is associated with the element’s reactivity. Elements with the same number of valence electrons behave in a similar way in reactions and so are grouped together in the same column on the periodic table.
What does the amount of valance electrons determine about an element?
Its row in the table.
Its atomic number.
Its atomic mass.
Its reactivity with other elements.
In the periodic table, similar elements are arranged in vertical columns called groups. Some of the major groups include Group 1: alkali metals; Group 2: alkaline earth metals; Group 17: halogens; and Group 18: noble gases. Elements within each group have similar properties and characteristic behaviors because of their similar numbers of valence electrons.
In what direction are groups arranged in the periodic table?
Side to side
Up and down.
Diagonally
In sections.
Elements in the same group or column have the same ...
