Answer:
Calcium becomes an ion with a charge of 2+
Oxygen becomes an ion with a charge of -2
Explanation:
since calcium lost two electrons, it has 20protrons, but only 18 electrons. this makes calcium a positive ion with a charge of 2+
An oxygen molecule consists of two oxygen atoms that have a double bond between each other and share valence electrons. the oxygen ion is formed when the atom of oxygen gains two valence electrons. this results in an oxygen ion with a charge of -2

One major advantage with the use of renewable energy is that as it is renewable it is therefore sustainable and so will never run out. Renewable energy facilities generally require less maintenance than traditional generators. Their fuel being derived from natural and available resources reduces the costs of operation.and alternative energy is a vital group too
