Question

the chemical symbol for the element calcium is ca. what would be the symbol representing calcium atoms that have lost two electrons? ca ca ca ca

Explanation:

When an atom loses electrons, it forms a positively - charged ion (cation). The number of electrons lost is indicated as a superscript positive charge. Calcium (\(Ca\)) losing two electrons means the charge is \(+ 2\), and the symbol for the ion is \(Ca^{+2}\).

Answer:

\(Ca^{+2}\)
