Class 12

1H (protium), 2H (deuterium), and 3H (tritium) are the three naturally occurring isotopes of hydrogen (tritium). An unstable nuclei (4H to 7H) have been created in the lab, but they do not exist in nature. With a half-life of 12.32 years, tritium is the most stable radioisotope of hydrogen. All heavier isotopes are created artificially […]

It is the first element in the periodic table and the most abundant element on the planet. It exhibits similarities to alkali metals as well as halogens in its structure. Despite the fact that scientists have recently discovered hydrogen in its metallic form through research and experiments. Unlike alkali metals, it has only one electron

The hydrogen element has multiple similarities with both alkali metals and halogens. Hydrogen is one of the most important fuels and is becoming popular each day as the amount of heat it produces during combustion. This hydrogen as a fuel study material will talk about hydrogen fuel, its uses, advantages, applications, and other comparisons for

Introduction Hydrogen is a chemical element. Its atomic number is 1 and the symbol is H. So, it appears as H on the top of the periodic table. However, in nature, it exists as a diatomic molecule (H2) – as an odourless and colourless gas. It was discovered by Henry Cavendish in 1766. Hydrogen is

The chemical compounds composed of hydrogen atoms are known as group 14 hydride. Moreover, group 14 contains the elements like carbon, Germanium, lead, Silicon, tin, and flerovium as there are two types of hydrides- Tetrahydride and Hexahydride. Group 14 hydrides contain straight-chain saturated following the formula XnH2n+2. However, alkanes also have the same formula. Other

Hydrogen is the first element of the periodic table. It is an odourless, tasteless and colourless gas under normal conditions. It is made up of diatomic molecules H2, and it is represented by the symbol H having atomic number 1. Hydrogen is made up of one electron and one proton. It is one of the

Hydrogen is made up of one electron and one proton. It is one of the significant components of water (H20) and all the other organic substances present on the Earth. Saturn and Jupiter are made up of hydrogen, which shows that this gas is spread out. Like other alkali metals, it contains one electron in

The most common element in the universe is hydrogen. Its name is derived from the Greek terms hydro, which means water, and genes, which means to create. In its molecular state, it is found as dihydrogen. It is the most essential component of the solar system, accounting for 70 per cent of the Earth’s total

Hydrogen is a chemical element with the symbol H and the atomic number 1. Hydrogen is the lightest element. Hydrogen is a gas made of diatomic molecules with the formula H2 under normal conditions. It has no odour, no colour, is non-toxic, and is very combustible. Hydrogen is the most prevalent chemical element in the

In 1913, Niels Bohr proposed the atomic Hydrogen hypothesis. It is  a positively charged nucleus made up of protons and neutrons that is surrounded by a negatively charged electron cloud, according to him. In the model, electrons are arranged in atomic shells around the nucleus. Electrostatic interactions between the positive nucleus and the negative surrounds
