Subjective Type

Study the extract of the Periodic Table given below and answer the questions that follow. Give the alphabet corresponding to the element in question. DO NOT repeat an element. (i) Which element forms electrovalent compound with $$G$$? (ii) The ion of which element will migrate towards the cathode during electrolysis? (iii) Which non-metallic element has the valency of 2? (iv) Which is an inert gas?

Solution

(i) See image.
Group 2 metal will form electrovalent compound with group 17 element.

(ii) $$A$$ [Positive ions migrate towards cathode, hence $$A$$ will form $$A+$$ and migrate towards cathode]

(iii) Group 16 elements have valency of 2 i.e. element $$E$$

(iv) Group 18 is known as noble gas group (inert gas) i.e. $$F$$
