This is why some atoms lose/gain electrons The path in which electrons orbit the nucleus of an atom A charged (positive or negative) atom that results from gaining/losing electrons in the outermost energy level A question is: How is the speed of the car effected by the type of wheels? The size of the engine is... A subatomic particle that has a negative charge and orbits the nucleus A question is: How is the speed of the car effected by the type of wheels? The type of wheels is the... Anything that has mass and takes up space 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 building block of matter The central core of an atom containing protons and usually neutrons. Positively charged particle in the nucleus of an atom The reason why atoms lose, gain, or share electrons
