question\nwhat is the difference in the number of electrons between the calcium ion and elemental calcium?\nprovide your answer below:\n\n□ electrons
Answer
Explanation:
Step1: Determine electrons in elemental calcium
Calcium (Ca) has an atomic number of 20. So, elemental calcium has 20 electrons.
Step2: Determine electrons in calcium ion
Calcium ion ($Ca^{2 +}$) forms by losing 2 electrons. So it has 20 - 2=18 electrons.
Step3: Calculate the difference
Difference = 20 - 18 = 2 electrons.
