When the calcium atom loses electrons, it's charge increases by the number of electrons lost.
It loses 2 electrons, so it's charge increases by 2.
The answer is +2
The line segment is 6 units long.
Plug it into the distance formula.
d= (sqrt) (x2-x1)^2 +(y2-y1)^2
d= (sqrt) (17-17)^2 + (33-(-21)^2
d=(sqrt) (0)^2 + (33 +21)^2
d= (sqrt) (54)^2
d= (sqrt) 2916
d=54
The distance is 54 units.
I hope this helps!
