the chemical symbol for the element calcium is ca. what would be the symbol representing calcium atoms that…

Explanation:

Step1: Understand ion - formation

When an atom loses electrons, it becomes a positively - charged ion.

Step2: Determine charge for calcium

Calcium loses 2 electrons. Each electron has a charge of - 1, so losing 2 electrons gives a charge of + 2.

Step3: Write ion symbol

The symbol for a calcium ion with a + 2 charge is $Ca^{2 + }$.

Answer:

$Ca^{2 + }$ (corresponding to the option $Ca^{+2}$ in the multiple - choice list)
