Protons, Neutrons and Electrons Explained - what's the difference?

This video tutorial explores the three subatomic particles: protons, neutrons, and electrons. It explains their roles in the atom, including how protons determine the element's identity, neutrons affect atomic mass and create isotopes, and electrons influence chemical reactivity and charge. The video also discusses the implications of changing the number of these particles, such as altering the element, mass, or charge, and provides a summary of these concepts.

What happens when you change the number of protons in an atom?

• The element changes.

• The mass changes.

• The charge changes.

• The atom becomes an ion.

Which subatomic particle is responsible for buffering protons in the nucleus?

• Photon

• Neutron

• Electron

• Proton

How does changing the number of neutrons affect an atom?

• It changes the mass.

• It changes the element.

• It changes the charge.

• It changes the color.

What is the main role of electrons in an atom?

• Determining the element's identity

• Contributing to the atom's mass

• Buffering protons in the nucleus

• Influencing chemical reactivity

What results from changing the number of electrons in an atom?

• The atom's mass changes.

• The atom becomes an isotope.

• A new element is formed.

• The atom's charge changes.
