Question

Element X has electronic configuration 2.8.1. Element Y has electronic configuration 2.6. What is the formula of the compound formed between element X and Y? ​

Answer 1

Answer:

Sodium Oxide

Explanation:

Compound with electronic configuration 2.8.1 would have an atomic number 2+8+1 = 11. This compound would be sodium (Na) [Natrium].

Compound with electronic configuration 2.6 would have an atomic number 2+6 = 8. This compound would be oxygen (O).

Therefore, X + Y  =>  Na + $O_{2}$   ⇒    $Na_{2} O$
