<u>Answer:</u> The atom will neither gain or loose electrons.

<u>Explanation:</u>

Every element obeys octet rule which is defined as the rule in which an atom occupies eight electrons in its outermost shell.

We are given:

Number of valence electrons or number of electrons present in outermost shell = 8

The above given element is already stable because it is obeying octet rule completely.

Thus, this atom will neither gain or loose electrons to be stable.

Mg + 2H2O -----&gt; Mg (OH)2 + H2<br><br><br> Write it in word problem
diamong [38]

The word problem format to the task given above is: When magnesium reacts with steam, it produces magnesium hydroxide and liberate hydrogen gas.

<h3>How magnesium hydroxide is formed?</h3>

It happens that magnesium is an alkali earth metal and react with water in the gaseous state to librate hydrogen gas, when this reaction occurs, it results in the formation of magnesium hydroxide.

The chemical equation between magnesium and water is given below:

Mg + 2H₂O -----> Mg (OH)₂ + H₂

So therefore, we can accurately deduced that magnesium hydroxide is produced when magnesium is disolved in water.
