Why has the Atomic Theory changed over time?

• Due to changes in political ideologies
• Because of the influence of social media
• As a result of climate change
• Due to new discoveries and advancements in scientific research.

What did John Dalton think the atom looked like?

• Glowing, liquid orb
• Tiny, solid sphere
• Hollow, metallic cube
• Invisible, intangible cloud

Where is the electron found?

• Nuclear core
• In the atmosphere
• Inside the nucleus
• Electron cloud

Why are elements organized in the periodic table by their atomic structure?

• To organize them by color
• To alphabetize them
• To group them by smell
• To show patterns in their properties and behavior

Why to elements in the same group behave similarly?

• Because they have the same number of valence electrons.
• Because they have the same number of protons.
• Because they have the same mass number.
• Because they have the same atomic number.

What role does the valence electron play in the structure of an element?

• Plays no role in the structure of an element
• Determines the chemical properties and reactivity of an element
• Determines the color of an element
• Affects the boiling point of an element

What is weak nuclear force?

• A type of energy drink
• The force that causes objects to fall to the ground
• One of the four fundamental forces of nature, responsible for the radioactive decay of subatomic particles.
• The force that holds atoms together

What is strong nuclear force?

• Force that holds the nucleus of an atom together
• Force that attracts electrons to the nucleus of an atom
• Force that causes the decay of the nucleus of an atom
• Force that repels the nucleus of an atom
