Hydrogen can be said to be the heart of chemistry, from students to experts, if one has even a little bit of chemistry knowledge. They would probably be heard of hydrogen. Naturally, Hydrogen exists in the form of water (H20) or gas on earth. Having only one shell and 1 proton orbiting it, Hydrogen is […]

INTRODUCTION Hydrogen Structure The structure of a hydrogen atom consists of one proton and one  electron held together by electrostatic forces. It consists of one electron in its outermost shell, making it equally easy to either lose an electron or gain an electron to attain a noble gas configuration. Qualities Hydrogen has an atomic number

Position of Hydrogen Hydrogen is the first element in the periodic table and falls under the top most alkali metals. This is why the structure of hydrogen is similar to the entire element that falls in alkali metals. The position of Hydrogen in the periodic table is first because its atomic number is 1. This means

Hydrogen is the simplest substance in the universe. This is the first element in the periodic table. It also has properties in common with alkali metals and halogens. In recent studies and tests, scientists have discovered Hydrogen in its metallic condition. It, like other alkali metals, has one electron in its valence shell and creates

 Decimal Logarithm of the reciprocal of the hydrogen ion activity, aH+, in a solution is used to calculate pH. pH = -log[aH+] For example, the argument of the logarithm for a solution with a hydrogen ion activity of 5×10-6 (at that level, this is effectively the number of moles of hydrogen ions per litre of

The percentage by mass of each element present in a compound is defined as Percentage Composition. It is calculated from the molecular formula by dividing the mass of a single element in one mole of a compound by the mass of one mole of that compound. The value is defined or expressed as a percentage.. 

NH4OH has a high basicity. In the presence of hydrogen ions, a solid base can ionise completely. As a result, in the presence of H+, OH– will be totally ionised, resulting in the formation of water and a complimentary salt from its counterpart. Let us consider the case of a solid base of NaOH that

Hydrogen is the most prevalent element present in the universe, and hydrogen makes up most of the Sun and other stars. According to studies, hydrogen atoms make up 90% of the universe’s particles. Compared to any other element, hydrogen is the component with the most compounds, and water is also the most prevalent hydrogen compound.
