Introduction Nuclear reactions, as well as Chemical reactions, are 2 types of reactions that differ significantly in terms of how the components participate in these processes. Chemistry is primarily concerned with reactions involving the exchange & sharing of electrons. But even so, these reactions normally have little effect on the ... Read More

Introduction Dipole moments can be developed both in ionic and covalent compounds. It measures the separation of positive and negative charges in the molecule, and hence, can be considered for the measurement of polarity in molecules. The separation of charges in any molecule results in a dipole moment. This separation ... Read More

Introduction The electrical properties of solids are quantified by conductivity. The capacity of a substance to transport electrical energy is referred to as its electrical conductivity. A good conductor may therefore easily carry electric current without melting, boiling, or otherwise changing its chemical makeup. Solids don't all have the same ... Read More

Introduction An electrochemical cell is a system that can generate electrical energy from spontaneous chemical reactions. Lets discuss it further, How does the battery in a mobile phone charge when it is plugged into its charger or how does the cell in a TV remote control function? In the scientific ... Read More

Introduction Typically, the copolymer is made up of repeating units of 2 different monomers. Block copolymers, alternative copolymers as well as graft copolymers are some types of these copolymers. Replicating units are placed arbitrarily in random copolymers; alternative copolymers have them in an ordered fashion; block copolymers have monomers placed ... Read More

Introduction Cyanide contains the a $\mathrm{CN-}$ functional group. The carbon atom that makes up this group, the cyano group, is triple bonded to a nitrogen atom. Cyanide anion and nitrile anion are other names for it. Cyanide can be produced by certain bacteria, algae, and fungi. In addition, it can ... Read More

Introduction The d block elements are assigned to groups 3 to 12, while the F block elements have their 4f as well as 5f orbitals eventually filled. Those are often called transition elements since they have numerous oxidation states because of the presence of unoccupied d orbitals within those elements, ... Read More

Introduction A synthetic element is called darmstadtium. Mendeleev foresaw it and gave it the name eka-platinum, which was later changed to element 110. It was created in 1994 at the German GSI Helmholtz Centre for Heavy Ion Research by Peter Armbruster and Gottfried Munzenberg. Its symbol is Ds. Nickel $\mathrm{(Ni)}$ ... Read More
