A chemical compound is a chemical substance composed of many identical molecules (or molecular entities) containing atoms from more than one chemical element held together by chemical bonds. A molecule consisting of atoms of only one element is therefore not a compound. A compound can be transformed into a different substance by a chemical ...
May 6, 2024 · A chemical compound is a substance composed of identical molecules of two or more elements. Learn about the basic types of compounds (molecular and ionic), their properties, and how they are formed and classified.
Learn how atoms form covalent and ionic bonds to create molecules and compounds. Explore different ways to represent and draw molecules using chemical formulas, structural formulas, and 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.

Jul 12, 2023 · The atoms in chemical compounds are held together by attractive electrostatic interactions known as chemical bonds. Ionic compounds contain positively and negatively charged ions in a ratio that results in an overall charge of zero. The ions are held together in a regular spatial arrangement by electrostatic forces.
