What is the ratio of anion cation for calcium oxide?
Cation:Anion :: 1:1 : Ca^(2+) : O^(2-) The charges balance at '2' , but are opposite (+/-) Because they are opposite, they come together like the N & S poles of a magnet, to form the ionic compound 'CaO ' Calcium oxide/lime.
Is calcium oxide a covalently bonded compound or a ionically bonded compound?
Calcium oxide is an ionically bonded compound that contains equal numbers of calcium cations with a charge of +2 and oxide anions with a charge of -2.
Is CaCI2 an acid base salt or oxide?
CaCl2, or calcium chloride, is a salt composed of a metal cation (calcium) and a non-metal anion (chloride). It is not an acid, base, or oxide.
What is the ionic formula of calcium oxide?
The ionic formula of calcium oxide is CaO, where calcium is the cation with a 2+ charge and oxygen is the anion with a 2- charge. The charges balance each other out in a 1:1 ratio to form a neutral compound.
Is calcium oxide covalently bonded or ionically?
Calcium is a metal with an electronegativity of 1.0 and oxygen is a nonmetal with an electronegativity of 3.5. The electronegativity difference is 2.5, and anything over 1.7 indicates an IONIC BOND.
What is the electron configuration of calcium IN calcium oxide?
The electron configuration of calcium in calcium oxide (CaO) is 1s2 2s2 2p6 3s2 3p6 4s0. Calcium loses its two outermost electrons to form the Ca2+ cation in the oxide compound.

CaCl2, or calcium chloride, is a salt composed of a metal cation (calcium) and a non-metal anion (chloride). It is not an acid, base, or oxide.
What is an example of a force of attraction?
An example is calcium(11)oxide. Ca^2+ cation interact with O^2- anion
What is the ionic formula of calcium oxide?
The ionic formula of calcium oxide is CaO, where calcium is the cation with a 2+ charge and oxygen is the anion with a 2- charge. The charges balance each other out in a 1:1 ratio to form a neutral compound.
What are the subscripts for the formula unit CaO?
No subscripts are needed: The formula unit for calcium oxide contains one calcium cation with a charge of +2 and one oxide anion with a charge of -2.
Is calcium oxide covalently bonded or ionically?
Calcium is a metal with an electronegativity of 1.0 and oxygen is a nonmetal with an electronegativity of 3.5. The electronegativity difference is 2.5, and anything over 1.7 indicates an IONIC BOND.
Is aluminum oxide a cation or an anion and what is the symbol?
Al2O3 - aluminum oxide (dialuminium trioxide); this oxide is not a cation or anion but a chemical molecular substance.
What is the word equation for extraction of calcium from calcium oxide by electrolysis?
The word equation for the extraction of calcium from calcium oxide by electrolysis is: Calcium oxide (solid) -> Calcium (liquid) + Oxygen gas.
Which atom becomes the cation in calcium chloride?
Calcium becomes the cation in calcium chloride. As a metal, calcium loses two electrons to achieve a full valence shell, acquiring a +2 charge to become a cation.
How much elemental Calcium is there in Calcium oxide?
There is no elemental calcium in calcium oxide. Calcium oxide is a compound made up of calcium and oxygen atoms bonded together. When calcium oxide reacts with water, it forms calcium hydroxide, which contains calcium ions but not elemental calcium.
