Basic chemistry concepts that I want to know!
| Front | Describe the difference between ionic and covalent bonds. |
| Back | Ionic Bonds: These are formed through the electrostatic attraction between positively and negatively charged ions. This bond is generally formed between metals and non-metals, where one atom (typically the metal) loses one or more electrons, becoming a positively charged cation, and the other atom (typically the non-metal) gains those electrons, becoming a negatively charged anion.Covalent Bonds: These are formed by the sharing of electrons between atoms. This type of bonding typically occurs between non-metals. |
| Front | What is electron affinity? |
| Back | The electron affinity (Eea) of an atom or molecule is defined as the amount of energy released when an electron attaches to a neutral atom or molecule in the gaseous state to form an anion. X(g) + e− → X−(g) + energy |
| Front | Define electronegativity. |
| Back | Electronegativity, symbolized as χ, is the tendency for an atom of a given chemical element to attract shared electrons (or electron density) when forming a chemical bond. |
