Right, let's go. Step 1: Describe elements with similar chemical properties. Elements with similar chemical properties are typically found in the same group (vertical column) on the periodic table. This similarity arises because they have the same number of valence electrons, which dictates how they interact and form chemical bonds. Step 2: State two ways the speed of a car can be changed. Assuming the question asks for ways to change or increase the speed of a car: • By increasing the engine's power output (e.g., pressing the accelerator pedal), which applies a greater forward force. • By reducing resistive forces such as air resistance or friction, allowing the car to accelerate more easily or maintain speed with less power.
