Q. 274.8( 4 Votes )

The position of some elements A,B,C,D,E,F and G in the Modern Periodic Table is given as under:


a. In which group are inert elements placed?

b. What type of ions would B, C, E and F form?

c. Which elements would have chemical properties similar to C?

d. How many shells would A have?

e. What is the similarity between A and D?

f. Identify the most abundant element in the earth’s crust.

Answer :

(a) Inert elements are placed in group 18.


(b) Elements B and E are placed in group 16 that means these have 6 electrons in outermost shell and these elements require 2 electrons to acquire noble gas configuration. So elements B and E will form B2- and E2- type ions.


And elements C and F are placed in group 17 that means these have 7 electrons in outermost shell and these elements require only 1 electron to acquire noble gas configuration. So elements C and F will form C- and F- type ions.


(c) We know that elements with similar properties are placed in same group. So element F would have chemical properties similar to C.


(d) Since A is placed in 1st period so it has only one shell.


(e) A and D are placed in group 18 so these both elements have 8 electrons in outermost shell.


(f) Most abundant element in the earth’s crust is B because B is oxygen and oxygen is most abundant element in earth’s crust.
