Which of the following elements would lose an electron easily?
Mg
Na
K
Ca

Academic Chemistry NCERT Class 10

Correct answer: (c) K

Explanation: K loses an electron easily as it is a group 1 metal whose atomic number is greater than that of Na. Mg and Ca are group 2 metals and their tendency to lose electrons decreases on moving from left to right in a period of the periodic table.
