What Are Transition Elements? Properties, Periodic Table Location, and Atomisation Enthalpy

Transition elements, or d-block metals (Groups 3–12), feature partially filled d-orbitals and exhibit unique properties such as variable oxidation states, colored compounds, and catalytic activity. Located centrally on the periodic table, they have high atomisation enthalpy due to strong metallic bonding and unpaired d-electrons. Inner transition elements include lanthanides and actinides with f-orbitals.

Nuclear Transmutation: How Elements Change in Nature and Science

Nuclear transmutation changes one element or isotope into another by altering protons or neutrons. It occurs naturally (e.g., in stars, radioactive decay) or artificially (e.g., in reactors, particle accelerators). This process is key to element formation, medical isotope production, nuclear energy, and waste reduction. While gold can be transmuted, it’s economically unfeasible.

Properties of Matter: Physical, Chemical, and Functional Explained With Examples

Matter, which occupies space and has mass, exhibits both physical and chemical properties. Physical traits like density or color may be extensive or intensive, while chemical traits involve transformations, such as flammability or reactivity. Matter exists in distinct states -solid, liquid, gas, plasma, and Bose-Einstein condensate each with unique behaviors. Specialized properties aid in scientific and industrial applications.

Solute, Solvent and Solution- Definition, Difference between, Characteristics, Examples

A solution is a homogeneous mixture of solute and solvent. Solutes dissolve in solvents without settling, forming a single-phase system. Solvents determine the solution’s state and aid dispersion. Solubility depends on factors like temperature, pressure, and polarity. Types of solutions and solvents vary by state and composition. Examples include saltwater, soda, alloys, and perfumes.

Why is the Latent Heat of Steam So High? Find the Answer

Latent heat of steam is the energy required to convert water into steam without a temperature change. Water’s strong hydrogen bonds make its latent heat exceptionally high, requiring 2260 kJ/kg at 100°C. This property is essential in power plants, cooking, industries, and weather systems, making steam an efficient heat carrier in various applications.
