Alithium atom has three electrons. a fluorine atom has nine protons and nine electrons, with seven electrons in its outer energy level. using a diagram of the two atoms, explain how lithium fluoride forms with ionic bonding between the lithium atom and the fluoride atom

Ablock having mass m slides down an inclined plane. the force of friction between the block and the inclined plane is f, the block's weight is m g, and the normal force is n. (a) draw a free – body force diagram showing the forces acting on the block. (b) write down all relevant newton’s equations for a given situation.
