Molecular Formula — Research Starter
A molecular formula is a concise representation of the composition of a chemical compound, specifying the types and numbers of atoms present in a molecule. For example, the molecular formula for…
Molarity and Molality — Research Starter
Molarity and molality are two important concepts in chemistry used to express the concentration of solutions. Molarity refers to the number of moles of solute per liter of solution, denoted in units…
Metalloids — Research Starter
Metalloids are a unique group of elements that exhibit both metal-like and non-metal-like properties, making them distinct in the periodic table. This group includes germanium, arsenic, antimony,…
Melting Point — Research Starter
Melting point is a fundamental physical property that defines the temperature at which a solid transitions to a liquid. This transition occurs when the thermal energy of the atoms or molecules within…
Man-Made Elements — Research Starter
Man-made elements, primarily consisting of transuranium elements found in the actinide series and beyond, are artificially created substances that do not occur naturally in significant amounts. The…
Malleability — Research Starter
Malleability is a critical property of certain materials, particularly metals, that allows them to deform under compressive stress without breaking. This property is fundamentally linked to the…
Litmus Test — Research Starter
The litmus test is a simple method used to determine the acidity or alkalinity of an aqueous solution based on the color change of litmus, a dye derived from lichens. Litmus is sensitive to pH levels,…
Lewis Structure and Diagram — Research Starter
Lewis Structures and Lewis Dot Diagrams are visual representations used to depict the arrangement of valence electrons in atoms and their bonding interactions. Developed by chemist Gilbert N. Lewis in…
Isotopes — Research Starter
Isotopes are variants of chemical elements that have the same number of protons but differing numbers of neutrons in their atomic nuclei. This variation in neutron count leads to differences in atomic…
Ions — Research Starter
Ions are charged particles that can be either atoms or groups of atoms with an unequal number of protons and electrons, resulting in a net electrical charge. They come in two types: cations, which…
