Carbohydrates are compounds composed of just the 3 elements: carbon, hydrogen, and oxygen; in most cases following the formula Cx(H2O)y giving them their name.
Simple carbohydrates are all simple sugars (e.g. glucose, fructose, galactose, xylose, ribose, deoxyribose). Complex carbohydrates are polymers of simple carbohydrates and fall into 3 categories: complex sugars (e.g. sucrose, lactose, maltose), starches (e.g. corn starch, potato starch), and fiber (e.g. cellulose, pectin, dextrin, lignin).
- Glucose: a simple sugar that serves as a primary energy source for living organisms.
- Starch: a complex carbohydrate made up of multiple glucose units linked together, commonly found in plants.
- Cellulose: another complex carbohydrate composed of glucose units, but with a different structure that provides structural support in plant cell walls.

What 3 elements do all carbon compounds have in common?
All carbon compounds have carbon atoms, covalent bonds between carbon atoms and other elements, and exhibit organic chemistry properties.
What is the oxidation number of group 3 elements?
Group 3 elements typically have an oxidation state of +3. This is because they have 3 valence electrons that they can lose to form stable compounds.
What are common compounds for helium?
Common compounds for helium include helium-3 (He-3) and helium-4 (He-4), which are isotopes of helium. Helium is typically chemically inert and does not readily form compounds with other elements under normal conditions.
Which group generally loses 3 valence electrons and are almost always combined with other elements in nature?
Group 13 elements, such as Boron and Aluminum, generally lose 3 valence electrons and form compounds with other elements in nature. They are commonly found in minerals and ores in combination with other elements, due to their tendency to form stable compounds through electron loss.
What are facts about compounds?
Compounds are substances formed when two or more elements chemically combine in fixed proportions. Compounds have unique properties that are different from the elements that make them up. Compounds can be either molecular (formed by covalent bonds) or ionic (formed by ionic bonds).
Besides carbon name 3 other elements that make up most organic compounds?
Hydrogen, oxygen, and nitrogen are three other elements that make up most organic compounds.
Are compounds and elements a mixture?
No. Elements, compounds and mixtures are 3 different terms.
What are 3 essential properties of every material?
elements and compounds
Which of the four main organic compounds is the most abundant?
1 protien 2 carbohydrate 3 lipids 4 RNA
What compounds contain Hydrogen Oxygen and Carbon?
Compounds that contain hydrogen, oxygen, and carbon include carbohydrates (e.g., glucose, sucrose), organic acids (e.g., acetic acid, citric acid), and alcohols (e.g., ethanol). These compounds play important roles in biological processes and are common in organic chemistry.

Carbohydrates are composed of 3 elements. There can be how many carbon atoms?
Carbohydrates are composed of carbon, hydrogen, and oxygen. The number of carbon atoms in a carbohydrate molecule can vary widely, depending on the specific type of carbohydrate.
3 elements most often found in organic compounds?
Carbon, Oxygen, and Hydrogen.
Which group generally loses 3 valence electrons and are almost always combined with other elements in nature?
Group 13 elements, such as Boron and Aluminum, generally lose 3 valence electrons and form compounds with other elements in nature. They are commonly found in minerals and ores in combination with other elements, due to their tendency to form stable compounds through electron loss.
What are some covalent compounds with more than three elements?
Some examples of covalent compounds with more than three elements include sulfur dioxide (SO2), phosphorus pentachloride (PCl5), and dinitrogen tetroxide (N2O4).
