Question

The formula of element X having 19 electrons with oxygen is?

Answer 1

Answer:

X --- > K ( potassium )

potassium forms stable super oxide --- KO2

here oxidation state of K = 1  ;  O = -1/2

Explanation:

Answer 2

Answer :

• X element is potassium having 19 electrons.

Formula of element X having 19 electrons with oxygen :-

• 4K + O2 ⟶ 2k2O

Element X reacted with oxygen to form potassium oxide.

• Electronic configuration of Element X is 2 , 8, 8, 1
• Symbol of element X is K

The above reaction is an example of combination reaction .

⏺️Combination reaction :- composition reaction is a reaction in which two or more reactants are reacted to form a single product.

Example :-

• C + O2 ➡️ Co2
