Question

what happened to metallic character or moving left to right ​

Answer 1

Answer:

As we go from left to right the metallic character decreases and the non metallic character increases. Because as we move from left to right in a period, the number of valence electrons increases by one at each succeeding element but the number of shells remains same. Due to this effective nuclear charge increase

Answer 2

As we go from left to right the metallic character decreases and the non metallic character increases. Furthermore, the tendency of an element to gain electrons increases with increases in effective nuclear charge, so non-metallic character increases on moving from left to right in a period.
