Yes and No...\n\nAll Organic Compounds contain Carbon, but not all compounds containing Carbon are Organic.\n\nas quoted from my source, listed below...\n\n"An organic compound is any member of a large class of chemical compounds whose molecules contain carbon, with the exception of carbides, carbonates, carbon oxides and gases containing carbon.The study of organic compounds is termed organic chemistry. Many of these compounds, such as proteins, fats, and carbohydrates (sugars), are also of prime importance in biochemistry.\n\nThe dividing line between organic and inorganic is contended and historically arbitrary; generally speaking, however, organic compounds are defined as those compounds which have carbon-hydrogen bonds, and inorganic compounds, those without. Thus carbonic acid is inorganic, whereas formic acid, the first fatty acid, is organic, although it could as well be called "carbonous acid" and its anhydride, carbon monoxide, is inorganic"

Ionic compounds are basically defined as compounds where two or more ions are held next to each other by electrical attraction. One of the ions has a positive charge (called a "cation") and the other has a negative charge ("anion"). Cations are usually metal atoms, and anions are either nonmetals or polyatomic ions (ions with more than one atom).\n\nA molecular compound is made up of all non-metals. The bond that forms between the atoms is by the sharing of electrons, unlike ionic compounds, which are made by the transfer of electrons.\n\nIn the case of NaH, this is a ionic compount and this is a strong base. \n\nAcid is defined as a compound which donates a hydrogen ion (H+) to another compound (called a base). You can also see it this way: An acid is a proton donor and a base is a proton acceptor. The acid is said to be dissociated after the proton is donated.\n\nAbout naming of compounds, read the book. It's a long discussion.

Organic compounds all have carbon. No carbon in the molecular structure, then it is not organic. I don't think you can limit the number of classes to four. In living organisms, classes include carbohydrates, lipids, amino acids, and nucleic acids.  Almost all organic compounds fall into one these classes.

Bucky Balls / Fullerenes\n\narchitect Buckminster Fuller\n\ngeodesic dome\n\nEdit: just saw the rest of the question.\n\nI'm not sure for "these molecules are ___ carbon atom molecules." \n\nThe other two kinds of pure carbon are: diamonds and graphite.

In terms of chemistry, mixtures and compounds are irrelevant to each other.\n\nThink of it this way... the "opposite" of a compound is an element. Glucose is not an element (C6H12O6), so it must be a compound.\n\nTo: thekevinzhang: glucose is absolutely not an ionic compound. Don't talk when you have no clue what you're talking about.

Keywords:\n              Help\n\nCarbon has a unique place in our lives. Each living cell, food, wood, paper, petro-chemicals, cooking gas, perfumes, etc are all made up of carbon. Chemistry of carbon compounds is known as organic chemistry. Organic chemistry encompasses study of all carbon-hydrogen compounds. These are also called hydrocarbons. Inorganic carbon chemistry is the study of oxides, nitrides and allotropes of carbon.\n\nThere are many differences between organic and inorganic compounds. Organic compounds are mostly insoluble in water. They have low melting points and exist by forming covalent bonds. Inorganic compounds on the other hand usually dissolve in water and have high melting points. Inorganic compounds can be formed due to either ionic or covalent bonds. Another characteristic of organic compounds is that they are inflammable.\n\nCarbon has 6 protons, 6 neutrons and 6 electrons. Its chemical symbol is 12C 6. Its electronic configuration is 2 electrons in the K-shell, and 4 electrons in the L-shell. In principle it should either give up or borrow 4 electrons while forming compounds. But it doesn’t form ionic bonds at all. It likes to share its four electrons with other atoms and form covalent bonds instead. Carbon covalent bonds are the strongest in nature.\nWe might expect that a carbon atom to form three bonds of one kind using the p orbital electrons and one bond of another kind using the s orbital electron. But this does not happen!! The one 2s and three 2p orbitals mix together and give rise to four new altogether different types of orbitals. This is called  hybridization and is seen only in carbon atom. The four orbitals are at an angle of 109028’. This is called tetrahedral or sp3 (pronounced as sp three) type of hybridization. There are sp2 and sp types of hybridization also.

isomerism is classified into structural and stereo\nstuctural isomerism arises b/w two compounds when they differ in the structural arrangement of atoms. in organic it is divided into:\nchain\nposition\nfunctional\nmeta\nhowever in inorganic chemistry we have other classifications\n\nfor more and detailed information, u could go to google

Here's a hint: mixtures can always be broken down into other things.  \n1. Sea water is a mixture because it has a ton of different things in it, like salt and water and various microorganisms.  \n2. Cooking oil is a mixture.  It is a blend of various kinds of oils.  \n3. Coal is a pure substance.  It is made up of nothing but carbon atoms, pure to the atomic level. \n4. Steel is a mixture.  It is an alloy of different other metals, especially iron.  It also uses carbon.  \n5. Chili sauce has all sorts of ingredients.  I don't know what they are exactly, but there has to be stuff like different peppers and condiment bases.  It's definitely a mixture.  \n6. Bronze is a mixture.  It's another metal alloy made with tin, copper, and some other metals.  \n7. Sand is a mixture.  I live by the beach, and you can see variations in the grains' colors. They're not all the same, so it's a mixture of different kinds of sand. \n8. Gold is an element.  At 24 k, it's as pure as you need to be for practical purposes.  Pure substance.  \n9. Orange squash: well, it's all orange squash, but squash has the stem, the skin, the flesh, and all these different parts. The components themselves range from DNA to proteins to sugars and carbohydrates and other organic molecules.  Mixture.  \n10. Salt is pure.  Just NaCl, baby.  \n11. Milk has fats and proteins and carbs and water and vitamins.  Mixture. \n10. Oxygen is just oxygen, an element.  Pure substance. \n12. Air is a mixture of nitrogen, oxygen, carbon dioxide, water vapor, noble gases, and hydrogen.\n13. "Oranger" juice: same as milk, for the most part.  Mixture.  \n14. Coke: caffeine, carbonic acid, sugars... mixture\n15. Soil has all sorts of stuff in it. Mixture.

Ionic compound is usually non-metal reacting with metals.\nThat is positive ion forming a compound with negative ion.\nWe call the compound is ionic if the elements we've used have positive or negative charge.\n\nConvalent compunds have different story because they are sharing the electrons and they don't really have any charge.\n\nI don't know what you mean by exactly what kinds of elements make ionic compounds because almost all of them do! Except all the noble gases far right side of table will not react at all (Where there is argon).\n\nIt is that simple

Neither. Allotropes are different forms of a pure element.\n\nFor example, both graphite and diamond are pure carbon. They differ in the way the carbon atoms are bonded to each other, which gives them different physical properties.\n\nSince there is only one element present, allotropes cannot be compounds. Since there are not multiple compounds present, allotropes also cannot be mixtures.

I think you're lacking the basic concept of how materials exist chemically (in what state). Elements can combine to form compounds that have completely different properties from the original elements. Or elements can exist as themselves (which is very rare). Now, most of the time when us humans invent some chemical, from fertilizers to drugs, they are a mixture of compounds. A mixture is anything 'mixed' together, bot 'combined'. So, your fertilizer will have many elements in compound forms. If there are any life forms, such as bacteria in organic fertilizer, these are highly organized forms of thousands of chemical compounds,  integrated to perform certain functions.

Element: a substance where all the atoms are identical\n(Fe,Al,C,etc.......)\n\nCompound: a substance where atoms are combined by ionic or covalent bonds.(CO2,NaCl,etc.....)\n\nMixture: a substance where elements and&#92;or elements are in the same phase,but are not combined with strong bonds.(Hydrated salts. NaCl.H20, water and salt are combined as a mixture, iron powder with magnesium powder are a mixture,but they are not actually bonded.)
