X 8 16 , Y 13 27 , Z 18 40 represent atoms of three different elements: Which atom has tendency to: i) Lose electrons? ii)Gain electrons?

First we will write the electronic configuration of given elements: X 8 16 electronic configuration = 2 , 6 It has tendency to gain two electrons and achieve stable electronic configuration. Y 13 27 electronic configuration = 2 , 8 , 3 It is metal and has tendency to lose last three electrons and achieve stable electronic configuration. Z 18 40 electronic configuration = 2 , 8 , 8 It has stable electronic configuration, so neither it lose nor gain electrons.

X 8 16 , Y 13 27 , Z 18 40 represent atoms of three different elements: Which atom represents: i)A metal, ii)A non-metal, iii)An inert gas.

First we will write the electronic configuration of given elements: X 8 16 electronic configuration = 2 , 6 It is Non-metal as it has tendency to gain two electrons and achieve stable electronic configuration. Y 13 27 electronic configuration = 2 , 8 , 3 It is metal and has tendency to lose last three electrons and achieve stable electronic configuration. Z 18 40 electronic configuration = 2 , 8 , 8 It has stable electronic configuration, so neither it lose nor gain electrons. Hence it is an inert gas

X 8 16 , Y 13 27 , Z 18 40 represent atoms of three different elements: Which atom is: i) Electropositive ii) Electronegative

First we will write the electronic configuration of given elements: X 8 16 electronic configuration = 2 , 6 It has tendency to gain two electrons and it is electronegative in nature Y 13 27 electronic configuration = 2 , 8 , 3 It is metal and has tendency to lose last three electrons and it is electropositive in nature. Z 18 40 electronic configuration = 2 , 8 , 8 It has stable electronic configuration, so neither it lose nor gain electrons.
