Does the Ca plus 2 ion have more electrons than the Ca atom?
No, Ca2+ has 2 electrons LESS than Ca
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+
Is Ca2 plus likely to form How about Br- Ne- Ne plus?
Ca(2+) and Br- are common ions; the neon ion probable doesn't exist.
How does flocculation efficiency depend on charge?
Flocculation efficiency increases with increasing electrical charge on the flocculating species. For example, Al+3 > Ca+2, > Na+.
What is the most common charge element of calcium include plus?
The calcium cation is (Ca)2+.
What is the charge of Ca when it exists as a cation?
2+ will be the charge in Ca2+ ion
Is Ca plus 2 an ion?
yes.
What is the charge of the ion that calcium would form?
Calcium is in group 2. Therefore it's most probable charge is Ca2+.
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
Why does calcium have a charge of 2 plus?
Calcium donates two electrons (charged -2) in reaction with a nonmetal. Substracting this from the zero (of the non-charged element) it leaves the +2 charge of the ion Ca2+Ca --> Ca2+ + 2e-
Does the Ca plus 2 ion have more electrons than the Ca atom?
No, Ca2+ has 2 electrons LESS than Ca
For calcium ca write the numbers of electrons it must gain or lose to have 8 vlance electrons then calculate the charge of the ion that would form?
Ca must lose 2 electrons to have a complete 3n shell, which has 8 valence electrons. The ion would have a charge of 2+: Ca^2+.
Is this formula correct Ca(OH)2?
Yes, it is correct. Calcium has a +2 charge, and the hydroxide polyatomic ion has a -1 charge.
What charge do group 2 metal ion carry?
What charge would you find on a Group 2 ion?
Is CaCl2 polyatomic ion?
No, it is a salt made of 1 Ca2+ ion and 2 Cl- ions with no total net charge. Hope this helps
Does an alkaline earth metal element form an ion with a charge of -1?
Alkaline earth metals form cations withe the electrical charge +2.As an exceptional curiosity exist the ion Ca-.
