Study Notes
- Ion: An atom or molecule that has gained or lost one or more electrons, creating a charged species.
- Cation: A positively charged ion, formed through the loss of electrons by an atom.
- Anion: A negatively charged ion created when an atom gains electrons.
- Ionic charge: The charge on an ion, positive (cation) or negative (anion), determined by electron gain or loss.
- Combining capacity: An element's capacity to combine with other elements, represented by valency or the number of bonds it can form.
- Valence electron: An electron in the outermost shell of an atom and is responsible for forming bonds.
- Stable octet: Atoms tend to gain, lose, or share electrons to achieve eight electrons in their outer shell, similar to noble gases.
- Polyatomic ion: An ion composed of multiple atoms, typically held together by covalent bonds, carrying an overall charge.
- Binary compound: A chemical compound containing only two different elements, often a metal and a non-metal.
- Ternary compound: A chemical compound composed of three different elements, often involving a metal and two non-metals.
- Ionic bond: A chemical bond formed by electrostatic attraction between oppositely charged ions, usually between metals and nonmetals.
- Covalent bond: A chemical bond where two atoms share one or more pairs of electrons, usually between two nonmetals.
- Molecule: A neutral group of two or more atoms held together by covalent bonds.
- Binary covalent compound: A compound formed by two nonmetals held together by covalent bonds, the simplest form being a molecule like CO2.
- Reactant: A substance undergoing chemical change in a reaction, found on the left side of a chemical equation.
- Product: A substance produced in a chemical reaction, located on the right side of a chemical equation.
- Chemical reaction: A process converting one or more substances (reactants) into different substances (products).
- Chemical equation: A symbolic representation of a chemical reaction, indicating reactants, products, physical states, and balancing coefficients.
- Coefficient: A number placed before a chemical formula in an equation to balance it and represent relative amounts of reactants/products.
- Acid: A substance donating protons (H+) in a solution, typically with a pH less than 7.
- Base: A substance accepting protons (H+) or donating hydroxide ions (OH-) in a solution, usually with a pH greater than 7.
- Ionization: The process of an atom or molecule gaining or losing electrons to form ions, or the dissociation into ions for acids and bases.
- Dissociation: The breaking of an ionic compound into its constituent ions in a solution.
- pH scale: A scale measuring the acidity or basicity of a solution, ranging from 0 (strongly acidic) to 14 (strongly basic), with 7 as neutral.
- Neutralization: A chemical reaction between an acid and a base, producing water and a salt, typically reducing acidity or basicity.
