The deuteron is a stable subatomic particle, comprising a proton and a neutron. It is one of the two stable isotopes of hydrogen(H). It is actually the nucleus of a …
In a flowering plant, mineral such as water, mineral nutrients, organic nutrients, and plant growth, regulators are the substances that needs transportation over a small distance. Substances move by cytoplasmic …
Bohr Magneton is magnetic dipole moment associated with an atom due to orbital motion and spin of an electron. The Bohr magneton (symbol ) is a physical constant and the natural …
The Group 2 Elements of the modern periodic table are also known as the alkaline earth metals. The group 2 elements are Beryllium(Be), Magnesium(Mg), Calcium(Ca), Strontium(Sr), Barium(Br), and Radium(Ra). History …
Brewster’s Law gives the exact angle of incidence for different materials and wavelengths of light for which the reflected ray is completely polarised. This angle of incidence is called the …
Group 14 Elements also known as Carbon Family belongs to the p-block group in the modern periodic table developed by Dmitri Mendeleev. Group 14 consists of elements,Carbon(C), Silicon(Si), Germanium(Ge), Tin(Sn), …
Group 13 Elements are the first group of the p-block elements. This group is also called Boron Family. Elements of group 13 are Boron(B), Aluminium(Al), Gallium(Ga), Indium(In), Thallium(Tl), and Nihonium(Nh). …
Group 18 Elements are also known as Noble Gases or Inert Gases due to their properties of being odorless, colorless, monoatomic and low reactivity. The 7 naturally occurring noble gases …
The 18 Electron Rule is similar to the octet and duplet rules, as it is used to predict stability. There are two 18 electron rules to be precise; one is …
