The metal calcium is an Alkaline Earth element, which is found in Group 2 of the Periodic Table. All the Group 2 elements have two valence electrons, and these elements want to loan them both out. This will leave a calcium ion with a +2 charge. Because calcium wants to loan out both its valence electrons, it will form compounds based on its desire to do so. Calcium will form bonds in a one-to-one ratio with elements that want to borrow 2 electrons, like oxygen. The compound will be calcium oxide, with CaO as its chemical formula. In the case of elements that want to borrow just one electron, like fluorine, chlorine or any of the halogens, the Group 17 elements, it will form bonds in a one-to-two ratio. Calcium fluoride, CaF2, and calcium chloride, CaCl2, are examples. A link can be found below.

Why is the probable charge of an ion of calcium positive?
calcium is a metal which ionizes by electron loss,so a calcium ion has lost to electrons and the positive charge indicates electron deficiency.
Is calcium with a plus 1 charge a ion?
Yes - but it is rare - usually has a + 2 charge
What is the cation of calcium oxide?
Calcium and Oxygen are the atoms in Calcium Oxide.
Is calcium positive or negative charge?
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.
The carbonate ion CO3 2- has an overall charge of 2- so what is the empirical formula for calcium carbonate?
CaCO3
What is the charge on the monatomic ion that calcium forms in its compounds?
Calcium forms a 2+ ion.
What is the difference between a calcium ion and a sodium ion?
Sodium ions have a +1 charge, whereas calcium ions have a 2+ charge.
What Is the electric charge on calcium ion in calcium chloride?
+2.
Why is the probable charge of an ion of calcium positive?
calcium is a metal which ionizes by electron loss,so a calcium ion has lost to electrons and the positive charge indicates electron deficiency.
Indicate the number of electrons lost or gained by calcium and give the charge of the ion it forms?
loses 2 electrons to form a calcium ion with 2+ charge
What is the electric charge on the ion in the compound calcium oxide?
Well the charge on the compound would be stable (0) when bonded, because the Calcium has given it's electrons to the Oxygen atom. But the charge on the calcium ion itself would be 2+
Predict the charge that a calcium ion would have?
2+
How many charges does calcium have?
Calcium has a chrage of +2 or two positive charges
What is the electric charge on the calcium ion in the compound calcium oxide?
Well the charge on the compound would be stable (0) when bonded, because the Calcium has given it's electrons to the Oxygen atom. But the charge on the calcium ion itself would be 2+
What is the electrical charge of the chlorine ion?
A "cation" carries positive (+) charge. An "anion" caries a negative (-) charge. The charge carried in may be single or multiple.
Calcium chloride and sodium hydroxide is equals?
It would be unethical to use this service to answer exam or graded questions. CaCl2 + 2NaOH --> 2NaCl + Ca(OH)2 Calcium Chloride + Sodium Hydroxide --> Sodium Chloride + Calcium Hydroxide Why: Ca ion has 2+ charge Cl ion has 1- charge Na ion has 1+ charge OH polyatomic ion has 1- charge
Is calcium with a plus 1 charge a ion?
Yes - but it is rare - usually has a + 2 charge
