Question

Lewis dot structure of Ca^2+

Answer 1

Explanation:

The atomic number of calcium is 20 , and the atomic number of argon (a noble gas) is 18 , so calcium is on the second column of the periodic table. ... 2−2=0 , so Ca2+ has no valence electrons . Therefore, drawing the Lewis structure is actually not too hard; just write Ca , and mention somehow that it has a 2+ charge.
