Example of compounds includes water (H2O), Hydrogen Peroxide (H2O2), etc. You could see water’s chemical formula, it says it has 2 atoms of Hydrogen combined with 1 atom of oxygen and in hydrogen peroxide, it has 2 atoms of hydrogen and two atoms of oxygen.

May 6, 2024 · Chemical compound, any substance composed of identical molecules consisting of atoms of two or more chemical elements. All the matter in the universe is composed of the atoms of more than 100 different chemical elements, which are found both in pure form and combined in chemical compounds.
Oct 24, 2020 · A compound is a substance made of two or more elements chemically bonded in a fixed ratio. Learn the difference between a compound and a molecule, and see examples of compounds with formulas and names.
An example of a covalent compound is ammonia. The chemical formula of ammonia is NH 3 , which tells us that in a single molecule of ammonia, there is one nitrogen atom, and three hydrogen atoms. The structure of a covalent compound can be depicted through space-filling models as well as ball-and-stick models.
- Here, electrons and protons are depicted using spheres. But in reality, protons and electrons aren't...It makes sense for protons and electrons to be spheres since the shape would allow the mass of the particles to be evenly distributed from all side...
- when NaCl crystal dissolves in water , what happens to it? what happens to electrostatic attraction ...The electrostatic attraction between the Na⁺ ions and the Cl⁻ ions is still there. But the attractions between these ions and water molecules is gr...
- How does bonding (covalent vs ionic) determine the properties of a substance?Do you know what properties from these bonds make that happen ? I remenber seeing in another video that intermolecular h-bonds typically make for h...
- Is it possible for a molecule to lose all of it's electrons? Hydrogen for example?Absolutely, and hydrogen often makes a hydrogen ion (H+) which consists of only a proton
- Is there a limit to the number of electrons atoms can have, or is it specific to each element?Each shell is limited to the number of electrons per subshell: The first shell consists of an s-orbital, and so it will have max 2 electrons. The s...
- Does the bond really exist and you can observe, or its a only an illustration of a kind of force wit...The bonds exist as electromagnectic atractions that tend to hold the molecule together. They can be measured through spectroscopy with infrared, ul...
- In the "Ion and formation" part, can every elements form an ion?Elements tend to try and reach more stable electronic distribuitions, therefore they can loose or win electrons, forming ions, not all elements for...
- I still don't understand how there is no such thing as a molecule of an ionic compound. Earlier in t...Molecules are defined as two or more atoms connected by *covalent* bonds. That might seem arbitrary (especially since covalent and ionic bonds are...
- I have this question since the beginning and unfortunately nothing seems to clarify it. What is the ...Molecules consist of two or more atoms bonded together. Compounds are molecules with two or more different elements.
- Key points. Everything in the known universe is made up of the elements found on the periodic table. There are over 100 different element A pure substance which is made from only one type of atom.
- Elements. An element is a pure substance that cannot be broken down into any other substances. An element is made from just one type of atom The smallest particle of an element.
- The periodic table. There are 118 chemical elements. They are listed on the periodic table A table which lists all of the chemical elements and arranges them in a way that is useful.
- 1. A solid element. The particles are close together and arranged in a regular way. 2. A liquid element. The particles are close together and arranged in a random way.
Compounds. Another common term in chemistry is "compound." A compound is a chemical substance composed of two or more different elements. Compounds can be covalently or ionically bonded. For example, H A 2 O is a covalent compound because it contains hydrogen and oxygen (different elements) covalently bonded together.
A compound is a substance that contains two or more elements chemically combined in a fixed proportion. The elements carbon and hydrogen combine to form many different compounds. One of the simplest is called methane, in which there are always four times as many hydrogen particles as carbon particles.
