Why does the basic character decrease along a period? Give reasons.
(N/A) Due to an increase in nuclear charge,the tendency to lose electrons decreases. This reduces the metallic character and,consequently,the basic character decreases.
$(b)$ Due to the increased nuclear charge,the atomic size decreases,which leads to a decrease in the electropositive character.
