In a periodic table, on moving from left to right along a period, the metallic character of an element

A.decreases✓ Correct
B.increases
C.remains the same
D.first increases and then decreases
Explanation

The metallic and non-metallic character of the elements depends on the electro positivity and electronegativity character. The periodic table follows the following trend in the periodic table- (1) Across the period When we move left to right in the periodic table, tendency of the elements to release electrons from its orbital decreases. Thus, the electro positivity character decreases (2) Down the group When we move top to bottom in the periodic table, the tendency of elements to release electrons from its orbital increases. Thus, the electro positivity character increases.
