the chemical symbol for the element calcium is ca. what would be the symbol representing calcium atoms that have lost two electrons?\no ca⁻\no ca⁺\no ca⁻²\no ca⁺²
Answer
Brief Explanations:
When an atom loses electrons, it forms a positively - charged ion. The number of electrons lost is indicated by the positive charge on the ion. Calcium losing two electrons results in a +2 charge. The correct notation for a calcium ion with a +2 charge is $Ca^{2 + }$.
Answer:
Ca$^{+2}$
