Part of what you say is right; part is not right. On the whole, you are wrong.
1. Elements are not charged. All elements have a zero charge.
2. Elements form ions and the charge on the ion is determined by its location in the periodic table.
3. Yes, it is easier for Ca to lose two electrons than to gain 6 so calcium gets a +2 charge (not -2)
.
If you take your first sentence and substitute ion for the word element, that first sentence would be essentially correct.
On the calcium sentence, I would prefer you to say it is easier to lose those 2 etc instead of take less energy to lose....
Technically it takes energy (you're right on that) to pull that electron (or in the case of Ca those two electrons away) BUT when electrons are ADDED (for example to Cl or F or Br etc to form Cl^-, Br^-, I^- etc) energy is released.
If I were to explain to someone about how to find a charge of an element, would anyone agree with this:
The charge of an element is determined by the gain or lose of electrons. Depending on how close they are to the left/right side of the periodic table concludes their charge. For example, Calcium is 2 away from the left side, and it would take less energy to lose those 2 electrons than try to gain 6 more, so Calcium gets a -2 charge.
