The atomic number of an element X is 8 and that of element Y is 12. Write down the symbols of the ions you would expect to be formed from their atoms.

Academic Chemistry NCERT Class 10

X will form X^2- as its atomic number is 8 (2,6). So it needs 2 more electrons to fulfill its octet rule.

Y will form Y²⁺ as its atomic number is 12 (2,6,2). So it needs to remove 2 electrons to fulfill its octet rule.
