how does Ca form cation
Answers
Answer:
It forms cation by kissing one electron from valence shell..
Explanation:
Have you ever looked at a glass of milk and thought, I wonder what makes up that milk? Have you ever looked at a bone and wondered why it was hard and white? The answer to both of these questions lies in their chemical make-up, which contains a chemical element called calcium. Calcium is a chemical element found in nature. It is a metal with a chemical symbol of Ca.
Calcium is the fifth most abundant element in seawater and is very reactive by itself in nature. Calcium also has a positive charge of 2. This makes it an ion. An ion is an atom of a chemical element that has an unequal number of electrons compared to protons. Remember that electrons are negative charges, and protons are positive charges. In the case of the calcium ion, we have a calcium element with a positive charge of 2. Positively charged atoms are called cations. This simply means that the element calcium needs two more electrons to equal the number of protons that it has; this balances the charge, or makes it zero.
