compare and contrast between group 2 and group 1 elements having the following property the number of electrons in atoms the size of the atom the metallic character their tendency to lose electrons the formula of their oxides the formula of chloride
Answers
Answer:
the number of electrons
group 1 has outer electronic configuration of [X]ns¹
group 2 has outer electronic configuration of [X]ns²
where [X] is the preceding noble gas configuration to the Given element
size of atom
group 1 elements are generally larger than the group 2 elements
metallic character
group 1 elements have a more metalic character than group 2 elements and there hydroxides (of group 1) make one of the strongest bases
tendency to loose electrons
group 1 elements have a greater tendency to loose electrons than group 2 elements due to their valency of ns¹ and thus there more of screening effect
formula of oxide
group 1: M2O but it should be noted that Li forms monoxide, Na forms peroxide and the rest forms superior but under appropriate condition they also form monoxide and peroxides
group 2: MO
chlorides
group 1: MCl
group 2: MCl2
where M is the element in both the above cases
