A chunk of an unidentified element (let's call it element "X") is reacted with sulfur to form an ionic compound with the chemical formula X2S. Which of the following elements is the most likely identity of X?a. Mgb. Lic. Ald. Ce. Cl

Respuesta :

Answer:

The answer is B. Li

Explanation:

2Li will be needed to form an ionic compound because the known element sulphur requires 2 (two) electron to complete  its octet configuration.

So reacting with Lithium (2Li) will balance their electronic configuration.
