प्रश्न

Which of the following element would lose an electron easily?

(a) Mg
(b) Na
(c) K
(d) Ca

उत्तर

(c) K
K would lose an electron easily as it is a group 1 metal whose atomic number is greater than that of Na, which also belongs to group 1. Mg and Ca are group 2 metals and the tendency to lose electrons decreases on moving from left to right in a period of periodic table.
