Detailed Solution

The above statement is true. The metallic character goes on decreasing while going from left to right in a period because the tendency of atoms of the elements to lose electrons (or gain electrons) changes in a period of the modern periodic table. The progressive increase in the number of protons causes the nuclear charge to rise as we move from left to right in a period. Valence electrons are strongly attracted toward the nucleus when nuclear charge increases, making it difficult for atoms to lose electrons. Thus, the metallic character becomes less prominent. Therefore, the metallic character goes on decreasing on moving down a group.
