B-N VIDEO Exploring Atoms and Molecules

What are atoms primarily composed of?

• Protons and electrons

• Empty space

• Electrons and neutrons

• Protons and neutrons

What part of the atom contains the protons and neutrons?

• Nucleus

• Core

• Electron cloud

• Outer shell

What is the primary function of electrons in an atom?

• Create atomic structure

• Facilitate chemical bonds

• Generate energy

• Provide mass

What role do neutrons play in an atom?

• Carry a negative charge

• Generate electrical energy

• Carry a positive charge

• Provide stability to the nucleus

Why don't atoms pass through each other if they are mostly empty space?

• Because of their solid state

• Due to electrical repulsion between electrons

• Due to magnetic attraction

• Because of gravitational forces

How do atoms combine to form molecules?
