Question

Elements X, Y and Z have atomic number 6, 9 and 12 respectively which one:
(i) forms anion.
(ii) firms cation.
(iii) has four electrons in it's valence shells?
(iv) Type of bond formed between X and Z? give its molecular formula.
​

Answer 1

Answer:

Explanation:

(i) element Y having atomic no.9 has 2,7 configuration.

So , they have a great tendency to accept one e- and form anion

(ii) element Z having atomic no.12 have

2,8,2 configuration. So they have high tendency to lose e- and to form cation

(iii) element X having atomic number 12 has configuration 2,4.so,it has 4e- in valence shell.

(IV) element Z is metal and element Y is

Non-metal.

(v) ionic
