Chemistry Question on Modern Periodic Law And The Present Form Of The Periodic Table
In the periodic table, with the increase in atomic number, the metallic character of an element
A
decreases in a period and increases in a group
B
increases in a period and decreases in a group
C
increases both in a period and the group
D
decreases in a period and the group
Answer
decreases in a period and increases in a group
Explanation
Solution
Metallic character increases from the top to bottom in a group as a tendency to lose electrons increases. This increases the electropositive character and metallic nature. Metallic character decreases in a period from left to right. It is because the ionization energy increases in a period. This decreases the electropositive character and metallic nature.
