Remember the talk about the "outer electrons" you learned about? Sodium (Na) has 1 electron in the outer most electron orbital. Calcium (Ca) has, you guessed it, 2 electrons in its' outer most electron orbital. Can you explain the rest to yourself? Remember they had a neutral charge before becoming ionic.

∙ 16y agoCalcium is metal with 2 electrons in its outer electron shell. When it loses these electrons to become an ion it loses 2 negatively charged electrons which leaves the calcium ion as a double positive chrged ion. Because it only has 2 out of a wanted 8 electrons (-) in its outer shell, making it easier for this element to let go of these two electrons than take on 6 more electrons. This tendency to let two negative charges go (in other words subtracting -2) from its electron count gives the element a positive 2 charge in it stable (comfortable) state.

Wiki User
∙ 15y agoBecause calcium is a metal, it forms a cation (an ion with a POSITIVE charge) Specifically, Ca+2.

∙ 9y agoYes, by loosing its two valence electrons it becomes Ca2+ ion
Wiki User
∙ 8y agoCa atom loses 2 electrons to form cations. So the atom gets a -2 charge.
Wiki User
∙ 7y agoNo. When ionized it has a positive charge.

∙ 7y agoCalcium, the element, has no charge. As an ion, it has a positive charge of 2+, i.e. Ca^2+.

What is the charge of anion?
A cation has a positive charge and an anion has a negative charge.
What is the charge on a electron called?
the charge of a proton is called positive charge neutron- negative charge electron- no charge
A charge on a proton?
The charge on a proton is deemed to be POSITIVE. NB The charge on an electron is deemed to be NEGATIVE ( opposite charge) The charge on a neutron is deemed to be ZERO(NO CHARGE).
Is oxygen's charge positive or negative?
Oxygen has a negative charge.
Electrons carries a positive or negative charge?
Yes, they have a negative charge. Protons have a positive charge and neutrons have no charge, they are neutral.
What particles has a negative charge and which has a positive charge?
Negative charge = electron Positive charge = positron Positive charge = proton
What is the charge of anion?
A cation has a positive charge and an anion has a negative charge.
How is the bonding in calcium oxide different from the bonding in sodium chloride?
calcium is mdonating one electron to each chloride. This makes the calcium a positive charge and the chloride a negative charge. This is called ionic bonding (CaCl2)
What charge electron charge positive or negative?
Electrons carry a negative charge to balance out the positive charge of the proton.
What is the difference between a negative and a positive?
positive ions carry positive charge and negative ions carry negative charge
Does all matter have a negative or positive charge?
Electrons have a negative charge; Protons have a positive charge; and neutrons have no charge.
Is an atom a negative charge or a positive charge?
An atom with positive charge is cation.An atom with negative charge is anion.
What is the charge on a electron called?
the charge of a proton is called positive charge neutron- negative charge electron- no charge
Is b a negative or positive charge?
A positive charge
Which particle proton neutron or electron have a positive charge?
proton positive neutron neutral electron negative
What are the 2 types of electric charges?
Positive charge and negative charge
What part of an atom has a negative charge and what was a positive charge?
electrons = negative charge protons = positive charge neutrons = neutral charge
