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
Answer:
Ca$^{+2}$
Explanation:
Step1: Understand electron - loss
When an atom loses electrons, it becomes a positively - charged ion.
Step2: Determine charge for 2 electron loss
Since calcium loses 2 electrons, it has a charge of +2.
Step3: Write ion symbol
The symbol for calcium is Ca, and with a +2 charge, it is written as Ca$^{+2}$.
