The type of wheels is the... A charged (positive or negative) atom that results from gaining/losing electrons in the outermost energy level The path in which electrons orbit the nucleus of an atom A subatomic particle that has a negative charge and orbits the nucleus The reason why atoms lose, gain, or share electrons Anything that has mass and takes up space building block of matter A question is: How is the speed of the car effected by the type of wheels? The size of the engine is... This energy level must be filled for an atom to be stable. This is why some atoms lose/gain electrons Positively charged particle in the nucleus of an atom A question is: How is the speed of the car effected by the type of wheels? The speed of the car is.... A subatomic particle that has no charge and that is found in the nucleus of an atom The central core of an atom containing protons and usually neutrons.
