Formation of Ion

Formation of Ion An ion is an atom or group of atoms carrying positive or negative charge. Example Ca2+, O2-, SO42- etc. If a particle has equal numbers of protons (+) and electrons (-), the particle charge is zero, and the particle is said to be neutral. In a chemical reaction, electron(s) can be transferred … Read more

Chemical Bond

Chemical Bonds 2 types of chemical bonds are commonly formed between atoms, namely Ionic Bond Covalent Bond The Ionic Bond (Ionic Bond) By releasing or receiving electron(s), the atoms will become ions and consequently form ionic bond between the ions. Ionic bonds are always formed between metal and non-metal. For example, sodium (metal) react with … Read more

Stability of Noble Gases

Stability of Noble Gases Stability of Noble Gases Group 18 elements (Noble Gases) exist as mono-atom in nature. They are inert in nature and do not react with any other elements (or themselves) to form any chemical compounds. In other words, they are chemically very stable (or chemically very non-reactive). Duplet and Octet Electron Arrangement … Read more
