Question

Elements in the same blank on the periodic table have the same number of valence electrons

Answer 1

Answer:

• Yes, it is true that elements in the same blank on the periodic table have the same number of valence electrons.
• As, the periodic table is the systematic arrangement of the different elements based upon the different elements properties (both physical and chemical). As the groups are vertical blocks in which those elements are arranged which posses or has the same number of electrons inside there electronic configuration.

Answer 2

Elements in the same group on the periodic table have the same number of valence electrons. The "groups" are the column (or rows). groups are vertically and periods are horizontally.
