What force gravitational or electrical repels as well as attracts?
The electrical force can repel as well as attract. Like charges (positive-positive or negative-negative) repel each other, while opposite charges (positive-negative) attract each other. An example of this is when two positively charged particles repel each other, but a positively charged particle and a negatively charged particle attract each other.
What is the smallest piece of a chemical element called?
An ATOM!!!! An atom can be sub-divided in to protons, neutrons, and electrons.
What is a nuecleus orbited by?
A nucleus is orbited by electrons in an atom. Electrons are negatively charged particles that move around the positively charged nucleus in specific energy levels or orbits. The interaction between the electrons and the nucleus holds the atom together.
How is a model of an atom similar to a model of the solar system?
Both models involve a central, dense core (nucleus in an atom, sun in the solar system) surrounded by smaller objects (electrons in an atom, planets orbiting the sun). Additionally, both models describe the organization and interaction of these components within a defined space.
Would the angle of deflection of the charged particle be bigger or smaller if they had more mass?
The angle of deflection of a charged particle in a magnetic or electric field is not affected by its mass. The angle of deflection is determined by the charge and velocity of the particle, as well as the strength of the field.
