What would happen if a bowling ball collided with a standing pin?
What would happen if a bowling ball collided with a standing pin? When the bowling ball collides with the pins, the momentum the ball loses is equal to the momentum the pins gain. An object’s inertia resists changes its motion. The momentum and force of a rolling ball is greater than that of the pins. […]
Why do metals gain electrons?
Why do metals gain electrons? Metals: Metals like to lose valence electrons to form cations to have a fully stable octet. They absorb energy (endothermic) to lose electrons. The electron affinity of metals is lower than that of nonmetals. Nonmetals: Nonmetals like to gain electrons to form anions to have a fully stable octet. Are […]
