Question

elements xyz has atomic number 11 10 and 9 which of them is an anion identify metal and nonmetal what is the formula of compound formed between metal and nonmetal ​

Answer 1

Given :- 'x' has atomic number 11, 'y' has 10, and 'z' has 9.

⇒ The element 'z' will form an anion because its atomic number is 9( its electronic configuration is 2,7) i.e. it needs one more electron to complete its octet.

So, 'z' is a non-metal.

⇒ 'x' is a metal, because its electronic configuration is (2,8,1) i.e. it needs to lose one electron to form its octet.

The compound formed between 'x' and 'z' is...

⇒ xz
