ionic radius is 0.68×10-10m. Because W6+ has a small ion radius, high electricity price, strong polarization ability, and is easy to form complex anions, tungsten is mainly in the form of complex anions [WO4]2-, which combines with Fe2+, Mn2+, Ca2+ and other cations in the solution...
What is an ionic bond and a covalent bond?Answer and Explanation: An ionic bond is a bond formed whenonly one of its atoms or moieties transfer theelectrons, while covalent bond is formed when both atoms (or moeieties) shared their valence electrons to form the bond. An example of ionic...
What is an ionic equation?Ionic Equations:Some chemical compounds are soluble in water, for example, acids, bases and salts. When these compounds are associated in chemical reactions, you can show them in ionic form, which means showing them in their dissociated form as positive and negative ...
