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