<span>From the given balanced chemical reaction, it can be seen that each aluminum atom gains loses 3 electrons. Also, each copper atoms gains 2 electrons. The choice that would best give us the described scenario above is choice number 2. That is Each Al loses 3e- and each Cu gains 2e-. </span>
<span>The correct answer is option (2) i.e. Each Al loses 3e- and each Cu^2+ gains 2e-
When an atom X, loses an electron, it becomes, X^1+
When an atom X, loses two electrons, it becomes, X^2+
When an atom X, gains an electron, it becomes, X^1-
When an atom X, gains two electrons, it becomes, X^2-
So, Here, 2Al + 3Cu^2+ --> 2Al^3+ + 3Cu,
When each Al, loses three electrons, it becomes, Al^3+
When each Cu^2+, gains two electrons, it becomes, Cu^2+^2- = Cu</span>
A metal ion is a type of atom compound that has an electric<span> charge. </span>Such<span> atoms willingly lose electrons in order to build positive ions called cations.</span>
Nitrogen is a naturally occurring element that is essential for growth and reproduction in both plants and animals. It is found in amino acids that make up proteins, in nucleic acids, that comprise the hereditary material and life's blueprint for all cells, and in many other organic and inorganic compounds.
