Atomic Structure and Properties

The video tutorial introduces atoms and elements, focusing on protons, neutrons, and electrons. It explains their mass, charge, and location within an atom. The tutorial also covers the periodic table, atomic numbers, and how changes in protons affect elements. The session concludes with a brief overview of future topics.

What is the charge of a proton?

• Positive

• Variable

• Negative

• Neutral

Where are neutrons located within an atom?

• In the electron cloud

• In the nucleus

• In the atomic orbitals

• In the outer shell

What is the mass of an electron compared to protons and neutrons?

• Twice the mass of protons

• Equal to protons

• Equal to neutrons

• Negligible

What is another term for the electron cloud?

• Energy levels

• Nucleus

• Neutron zone

• Proton field

What does each element's square on the periodic table represent?

• The element's state of matter

• Only the element's name

• The element's atomic number, symbol, and atomic mass

• The element's color

What does the atomic number of an element indicate?

• The number of neutrons

• The number of electrons

• The number of protons

• The element's mass

How much of the atom's mass is contained in the nucleus?

• 50%

• 75%

• 99.9%

• 100%

What happens if the atomic number of an element changes?

• The element becomes unstable

• The element loses electrons

• The element remains the same
