This will form a negative ion - an anion. Electron Gain Enthalpy When electrons are introduced into the valence shell of an atom, the electron is stabilized as it is entering the attractive positive electric field of the atomic...
Two atoms can come together and form a covalent bond by sharing one or more of their valence electrons each. This is represented by one or more straight lines drawn between the connecting atoms, which are written using their elemental symbols. Some covalent bonds are pola...
bonds are formed when electrons are shared between atoms resulting in lower melting point and electrical conductivity. We also know that ionic compounds form strong interactions between ions resulting in higher melting point and electrical conductivity and covalent bonds are for...
aThe hydrogen bond is a weak bond,but than van der Waals force is strong.H2O has two hydrogen atoms.The oxygen atom has two lone pairs of electrons, which is easy to other hydrogen atoms to form hydrogen bonds, so H2O can form four hydrogen bonds.[translate]...

During electrolysis (flow of electrons when electricity is passed), the anode loses its mass as copper dissolves and the cathode gains mass as copper is deposited. Oxidation takes place at the anode by loss of electrons whereas the reduction takes place at the cath...
organic compounds containing nitrogen or sulphur, including heterocyclics, thioethers, mercaptans thioureas and nitriles; inorganic and organic ions including hydroxyl, halide, thiocyanate, and acetate; neutral inorganic groups which donate electrons to form co-ordinate bonds including water and ammonia....
Phosphorous can have an anion, P3-. This ion: a) is the result of the atom gaining three electrons. b) can form three ionic bonds. c) has eight electrons in the outside orbit. d) All of these choices are correct. What is the cha...
