Identify the correct statement related to metallic character.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. Metallic character decreases across a period and increases down a group.
Metallic character refers to an element’s ability to lose electrons and form positive ions (cations), a typical property of metals. As you move across a period in the periodic table (from left to right), metallic character decreases because the elements have increasing nuclear charge, making it harder to lose electrons. Conversely, as you move down a group, metallic character increases because atomic size increases, and the outer electrons are farther from the nucleus and more easily lost. Hence, metals are generally found on the left and bottom of the periodic table, while nonmetals are on the right and top.
