Neon and chlorine have atimic numbers 10 and 17 respectively. What will be their valencies?
Answers
Answer:
Neon-0 and Chlorine-1
Explanation:
Thus, one electron is gained to complete its octet and so its valency is 1. Neon have valency 0 because it lies in the outermost shell of an octet which is the first reason and the second reason is that neon is a noble gas and noble gases have their valency 0. Thus,neon's valency is 0
hope this helps....
Answer:electronic configuration of Neon (Ne) is 2,8.so it is seen that it has fully filled octet configuration. It cannot combine with any other chemical species. Thus , its valency is 0.Actually the valency is the no. of electron relesed or gained by one atom to attain octet configuration( depending on the configuration of outer most shell).So, incase of Chlorine ...its electronic configuration is 2 ,8,7.So, if it accepts an extra electron then it will have octet. so its valency is 1.
