Chemical bonding
STEM – round 2
Chemical bonding is one of the most interesting topic to learn about. Basically, a chemical bonding is a force of attraction between atoms or ions. It occurs when atoms share or transfer valence electrons. Valence electrons are the electrons in the outer energy level of an atom. There are three types of Bonding. One is the Ionic Bonds, second is the Covalent Bonds, and the third one is the Metallic Bonds
- Ionic Bond
- An ionic bond is the force of attraction that holds together positively charged ions. It forms when atoms of a metallic element give up electrons to atoms of a nonmetallic element. Metals “want” to give up electrons, and nonmetals “want” to gain electrons. Ionic bonds are really strong.
- Ionic compounds form crystals instead of molecules. Ionic bonds are strong and the crystals are rigid. As a result, ionic compounds are brittle solids with high melting and boiling points.
- Covalent bonds
- Covalent bond is when two elements share the electrons with each other.They share electron to form molecule, and two of the electron is called double bond. Note: They only share when they need to be share, and not always the same elements can share, but different elements can also be share.
- Metallic bonding
- Metals mean anything that are hard or conductive, they don’t really melt in a room temperature, but they will be melt in when the temperature is 800°c or 100°c. Metal observe the heat very fast and it conducts strong heat, too.
- A Metallic bond is a sharing of electrons between many atoms of a metal element.
These are what I know about chemical bonding based on what my teacher have taught me and some of my own research.
Did you know that Hydrogen bond is the weakest?. I know the answer, that is because they are easily and rapidly formed and then broken under normal biological condition.
Note: Rapidly means very quickly 🙂
