Give the formula for potassium nitrate. Is this compound ionic or covalent? What is the name of the compound with the formula K2CO3? Determine the formula for the compound that is formed between potassium and phosphorus. What is the chemical formula for sodium chloride?
What are the requirements for a solid ionic conductor? Provide an example. Why is water a better shield against neutrons than lead or steel? Why do we have free electrons in metal and not in insulators? What makes them be an insulator/semiconductor/metal? Why the f...

It is concluded that the K adatoms on the Si(100) surface are highly ionic while those on the Pt(111) and W(110) surfaces are characterized by covalent or metallic bonding. The ionic nature of potassium can be ascribed to the existence of the empty dangling-bond states and/or the bulk...

The Na+–K+ ATPase, or pump, is the primary transport system that maintains the ionic imbalance between the cell exterior and interior. That is, each pump cycle extrudes three Na+ ions out of the cell and transports two K+ ions into the cell, thus building up [K]i and reducing [Na...
Is the reaction of calcium chloride with sodium carbonate ionic or covalent? Which of the following is the way to detect procyanidins? A) When heated with dilute NaOH, procyanidins give a green colour. B) Procyanidins give a yellow colour with concentrated nitric acid. C) When heated...
