When combined with other elements, potassium (K) always forms a +1 ion. Oxygen (O), when combined with other elements almost always (with a few rare exceptions) forms a -2 ion. Therefore, when these combine to form a binary compound, the charges must balance out. Therefore there must be 2 K+ ions for each O2- ion because 2*1 = 2!
So the ratio must be 2 potassiums for each oxygen.
Three potassium oxides are known:
- K2O: 2 potassium atoms and 1 oxygen atom
- KO2: 1 potassium atoms and 2 oxygen atoms
- K2O2: 2 potassium atoms and 2 oxygen atoms
A compound containing potassium and oxygen atoms would have a formula of K2O, and would be named potassium oxide. This is a binary ionic compound.
No. Not all binary compounds are ionic and not all ionic compounds are binary. An ionic compound is a compound formed by the exchange rather than the sharing of electrons. A binary compound is any compound of exactly 2 elements. Examples: Sodium chloride (NaCl, compound sodium and chlorine) is both binary and ionic. Potassium hydroxide (KOH, compound of potassium, hydrogen, and oxygen) is ionic but not binary. Water (H2O, compound of hydrogen and oxygen) is binary, but covalent, not ionic.
No. It is a compound of the elements potassium, sulfur, and oxygen.
The name implies potassium and oxygen.
Potassium chlorate is KClO3 and it consists of potassium, chlorine and oxygen.
No. A binary compound contains two elements. Sodium sulfite, Na2SO3, contains three elements: sodium, sulfur, and oxygen.
Three potassium oxides are known: - K2O: 2 potassium atoms and 1 oxygen atom - KO2: 1 potassium atoms and 2 oxygen atoms - K2O2: 2 potassium atoms and 2 oxygen atoms
Patassion Oxide, K2O.
No. A binary compound contains only two elements. H2SO4 contains 3 elements hydrogen (H), oxygen (O), and sulfur (S)
No: a binary compound contains only two different elements. Calcium sulfate contains three elements: calcium, oxygen, and sulfur.
The chemical formula for the compound potassium carbonate is K2CO3. The elements potassium, carbon and oxygen are present. They are present in the ratio 2:1:3.
Potassium hydroxide is a compound of 3 elements: potassium, oxygen, and hydrogen.. It contains two ions: potassium (K+) and hydroxide (OH-).
No. Calcium sulfate contains 3 elements (calcium, sulfur, and oxygen). A binary compound contains exactly two elements.
Three elements (not two) make up the compound K2CO3 . They are potassium, oxygen and carbon.
I think it's One potassium atom to Two oxygen atoms. that's wrong it's Two potassium atoms to one oxygen atom. ------ Three potassium oxides are known: - K2O: 2 potassium atoms and 1 oxygen atom - KO2: 1 potassium atoms and 2 oxygen atoms - K2O2: 2 potassium atoms and 2 oxygen atoms
The binary compound is nitrogen and oxygen.
K2O, potassium oxide, is composed of the element potassium (K) and the element oxygen (O).
Yes, CO is a binary compound. It is formed by two different elements. C is Carbon and O is Oxygen. CO is Carbon monoxide.
Th elements contained in a compound are those whose chemical symbols are contained in the formula for the compound. For K2O, therefore, the elements are potassium and oxygen.
No, a binary compound consists of only 2 elements. Copper II Nitrate or Cu(NO3)2 contains 3 elements: copper, nitrogen, and oxygen.
An element can't be made from other elements and so this would become a compound. Examples of a metallic element combining with Oxygen to form a compound include: Magnesium + Oxygen --> Magnesium Oxide Potassium + Oxygen --> Potassium Oxide Zinc + Oxygen --> Zinc Oxide
Potassium chlorate is a compound containing potassium, chlorine, and oxygen atoms. It's molecular formula is KClO3.
A binary compound is a chemical compound that contains exactly two different elements. An example would be water containing hydrogen and oxygen, H2O.
Yes. It contains exactly two elements, carbon, and oxygen.
A binary compound of nitrogen and oxygen is nitrogen oxide.
