Classification of Elements and Periodicity

Halogens are a group of elements present in the periodic table. These elements can remain active at room temperature in three to four different states, i.e., liquid, solids and gases. The name halogen is derived from the Greek roots hal- (“salt”) and -gen (“to make”). They belong to the Group 17 of the periodic table […]

Alternatively, the oxidation state of an element can be defined as the degree of an element’s ability to lose electrons from its valence shell in a chemical compound. This is also referred to as the degree of oxidation of the element in question. During the formation of their compounds, transition elements exhibit a wide range

Group 18 of the Periodic Table contains the chemical element helium (He), which is an inert gas (noble gasses). Helium is the second lightest element (only hydrogen is lighter), and it is a colorless, odorless, and tasteless gas that turns into a liquid at a temperature of 268.9 degrees Celsius (452 degrees Fahrenheit). Helium has

Periodic trends are specific patterns in the periodic table that show different things about a certain element, like how big it is and how it behaves in electricity. Electronegativity, ionisation energy, electron affinity, atomic radius, melting point, and metallic character are some of the main periodic trends. Periodic trends, which come from the way the

Magnetism acts on the region surrounding a magnetic material or a moving electric charge in which the force of magnetism is present, known as the magnetic field. An observable magnetic field is a vector field that exists in the vicinity of a magnet, an electric current, or a changing electric field, and in which magnetic

Permanent magnets are objects manufactured from materials that have been magnetized and have the ability to generate their own persistent magnetic field. A common example is a refrigerator magnet, which is used to hold notes on the inside of a refrigerator door. Ferromagnetic materials are those that can be magnetized and are also those that

Lanthanides are rare earth elements in which the differentiating elements reach the 4f orbits. These are referred to as rare earth elements, although, in reality, they are not so uncommon. The difference between these elements is that they are difficult to separate from their series counterparts. The lanthanide is given to the elements because they
