Electrón

The video tutorial explains the characteristics of electrons, highlighting their small size and negative charge. It contrasts electrons with protons and neutrons, noting that electrons have virtually no mass, unlike the heavier protons and neutrons. The tutorial concludes by mentioning that these particles can be further broken down into smaller components.

What is a fundamental characteristic of electrons that is common to all atoms?

• They have a positive charge.

• They have a negative charge.

• They have a large mass.

• They are found only in metals.

How does the mass of electrons compare to that of protons and neutrons?

• Electrons have the same mass as neutrons.

• Electrons have more mass than protons.

• Electrons have virtually no mass.

• Electrons are heavier than both protons and neutrons.

Which particles are described as having virtually no mass?

• Protons

• Neutrons

• Electrons

• Atoms

Which of the following statements is true about protons and neutrons?

• They have a negative charge.

• They are much heavier than electrons.

• They cannot be broken down into smaller particles.

• They are lighter than electrons.

What can be said about the ability to break down protons and neutrons?

• They can be broken down into smaller particles.

• They are already the smallest particles.

• They are indestructible.

• They cannot be broken down further.
