1. How are ions formed from atoms? Attempt at Solution: From reading books and browsing on the internet I've collected a good amount of information, but I don't completely understand them. "An ion is formed when an atom gains or loses an electron in bonding with another atom, causing the atom to become a positive or negative ion. Since electrons are negative, if an atom loses an electron, there are more protons (which are positive) than electrons, which causes the atom to become a positive ion (sometimes called a cation.) If an atom gains an electron it becomes a negative ion (or anion.) Ions are most commonly formed when two elements undergo ionic bonding, in which the elements 'give and take' electrons to gain full outer shells." Can someone interpret that into a simpler format or give an example of an equation to demonstrate. Thanks.
