What is the electric charge on the calcium ion in the compound calcium oxide?
The electric charge on the calcium ion in calcium oxide is 2+. This is because calcium (Ca) forms a cation with a charge of 2+ when it loses two electrons to achieve a stable electronic configuration.
Does the Ca plus 2 ion have more electrons than the Ca atom?
No, the calcium ion Ca+2 has fewer electrons than the neutral calcium atom. The calcium atom has 20 electrons, while the Ca+2 ion has 18 electrons because it has lost two electrons to become positively charged.
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.
What is the formula for the salt which contains both Ca and NO3 ions?
The formula for the salt containing both Ca and NO3 ions would be Ca(NO3)2. This is because calcium (Ca) has a 2+ charge and nitrate (NO3) has a 1- charge, so to balance the charges, you need two NO3 ions for each Ca ion.
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+.
Is Ca plus 2 an ion?
No, "Ca plus 2" is not correct notation for an ion. The correct notation would be Ca^2+, which represents a calcium ion with a 2+ charge due to the loss of two electrons.
The chemical symbol Ca2 plus refers to the?
Calcium ion with a +2 charge.
Ions with a 2 plus charge?
two elements with ions with a 2 plus charge are Sulfurand Oxygen
What charge does Ca have when making an ion?
Calcium (Ca) typically forms a +2 charge when it becomes an ion by losing two electrons.
What is the charge of Ca when it exists as a cation?
2+ will be the charge in Ca2+ ion
WHAT IS THE DIFFERENCE BETWEEN CA AND CA2 plus?
Ca refers to calcium, which is a chemical element with the atomic number 20. Ca2+ refers to a calcium ion that has lost two electrons, resulting in a 2+ charge. The main difference is that Ca represents the neutral form of calcium, while Ca2+ represents the positively charged ion form.
What is the electrical charge of the chlorine ion?
The electrical charge of the chlorine ion is -1. This is because chlorine (Cl) gains an electron to achieve a full outer shell, giving it an extra negative charge.
Predict the charge that a calcium ion would have?
A calcium ion (Ca^2+) would have a charge of +2, as it loses two electrons to achieve a stable electron configuration.
What is the cation for AlBr3?
what is the cation for Ca(ClO4)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.
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?
Calcium (Ca) has 20 electrons. To have 8 valence electrons, it needs to lose 2 electrons. When it loses 2 electrons, it forms a Ca2+ ion with a +2 charge.
Is CaCl2 polyatomic ion?
No, CaCl2 is not a polyatomic ion. It is a compound made up of two different elements – calcium (Ca) and chlorine (Cl).
