Valence electrons: How do they relate to Ionic/Covalent bondsValence electrons are the outermost shell electrons of an atom. They determine an atom's properties, and are the main components of chemical bonding (Ionic/Covalent). Atoms need to balance out their outermost shells (a.k.a., valence electrons). They can't do this by themselves, they need another atom to help them!
This here is an example of Ionic bonding. In Ionic bonding, one of the atoms gives electrons from their outermost shell to the other atom. Therefore they try to become balanced by making their v.e. number equal to 2 or 8.
Sure Fluorine, I'm happy to bond with you :)
Hey Lithium, could you give me an electron please? you'll also be balanced and happy as well!
-Valence electrons are shared by the bonding of atoms.-High melting points-High boiling points-State at room temperature is solid-Happens between metals & nonmetals
Properties of Ionic / Covalent bonds
-Valence electrons are sent from one atom to the other-Low melting points-Low boiling points-State at room temperature is liquid or gas-Happens only between non-metals
Chemical bondings happen between atoms. Atoms are physically everywhere, as they make up everything physical. The things we touch, air we breathe, food we eat, the clothes we wear, are all created from physically-existing substances. And those substances are created by atoms of different elements & different chemical compounds & mixtures.Chemical bondings are important, because they hold molecules together and create connections of various substances & elements that are very important in our lives.
Real life applications of chemical bondings
Water, the most essential compound of all life, is made up of two Hydrogen atoms and one Oxygen atom. If there was no such thing as chemical bonding, those atoms could not bond together and form water, if there was no water there would be no life in our planet.
Biomolecule compounds & forming of Ethylene glycol, a type of carbohydrate
The Importance of chemical bonding is not just about water of course. All the proteins & carbohydrates we consume from food, the medicine we need to cure ourselves, are all formed with the help of chemical bondings. It is not just the things we consume, but also all the living beings and physically existing objects & environments.
