Periodic table of elements chart with atomic number, chemical symbol, element categories, and states of matter in a color-coded format for chemistry learning.

The Periodic Table of Elements: What It Is and How It Works

The periodic table is a scientific chart that organizes elements by atomic number and reveals patterns in chemical behavior. It helps explain how atoms bond, react and form substances. From noble gases to alkali metals, each group shares unique properties, all guided by electron structure-a key to understanding the elements of the universe.

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.

Which Property of Matter Is Used to Measure Temperature?

Temperature is measured using the property of thermal expansion, where matter increases in volume with heat due to increased particle motion. This expansion is predictable and used in thermometers and other devices. As temperature rises, particle spacing increases, causing expansion in solids, liquids, and gases, making thermal expansion a reliable way to measure temperature.

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.
