1.	Atomic number of elements A B C D E are 7 10 12 4 19. Which two elements are chemically similar. Which is an inerd gas. Which element belongs to third period of periodic table. Which element amoung this is the non metal
Answer» ONG>ANSWER: inert gas=configaration 10 which is neon non metal=7 nitrogen chemically simillar=12 and 4 as they have same valency, IE 2 valence electrons
