How do you explain why a calcium ion has a charge of 2?

Answer 1

It gains stability by loosing 2 electrons and acquiring +ve 2 charge....When calcium looses two electrons it attains an octet configuration of the nearest noble gas which is inert due to high stability......

Answer 2

• It must lose two electrons.
• This is because the protons are positive (+) and the electrons are negative (-). So that means when you have an even # of protons (+) and electrons (-), it is neutral. To get a charge of 2 Positive (+), you must have 2 more protons (+) than electrons(-).
• Therefore, it must lose two electrons (it can't gain two protons instead because when the proton # changes, you have a new element).

Answer 3

A calcium atom loses two electrons to achieve a full outer electron shell, resulting in a 2+ charge for the calcium ion. This loss of electrons leaves the calcium ion with 20 protons (positive charge) and 18 electrons (negative charge), giving it a net charge of 2+.

Answer 4

explain why a calcium ion has a charge of 2+.

Answer 5

Add calcium metal to warm water it forms calcium +2 ions in solution.

Answer 6

dont put questions without answers,makes your cite look terrible.

Answer 7

It loses 2 electrons.

Electrons have negative charge, so an atom must gain them to become negative, and lose them to become positive.
