Column 1
How is an atom structured?
What is: Subatomic particles made up of protons, electrons, and neutrons make up the atom
What makes up the nucleus of an atom?:
What is: Protons and neutrons
Last shall be first!
Your team receives the same points as first-place plus 100 more points.
What is the charge of the nucleus of an atom?
What is: Positive
How are the parts of an atom similar and/or different?
They are all subatomic particles, they all have mass
Protons and neutrons have the same mass while electrons are a lot smaller in mass They all have different charges
How do the location of protons, neutrons, and electrons compare?
What is: Protons and neutrons are found in the center (nucleus) while the electrons are found orbiting in the electron cloud
How do the masses of protons, neutrons, and electrons compare?
What is: Protons and neutrons have a mass of 1 AMU while electron has a mass 0 AMU (2000X smaller)
You lose a turn.
Your team loses this turn and the previous team takes your spot.
How do the charges of protons, neutrons, and electrons compare?
What is: Protons are positive (p+), electrons are negative (e-), and neutrons are neutral (n^0)
How do electrons and valence electrons differ?
Electrons are in energy levels called shells while the valence electrons refer to the number of electrons in the outermost shell
What makes up the mass of an atom?
The subatomic particles
What does atomic number represent?
What is: The number of protons and electrons
Daily Double!
All teams get to wager up to their points they've earned on the next question prompt. Answers are written on a piece of paper before the answer is given.
How is the identity of an element determined?
Use the atomic number (total number of protons), symbols
How does the atomic number differ from the atomic mass?:
What is: The atomic number represents the protons and electrons while the atomic mass represents the protons and neutrons
How can you determine the number of subatomic particles in an atom?
What is: Mass number- Atomic number= # neutrons
How can the Periodic Table be used to determine an element’s atomic structure?
What is: The atomic number or the total number of protons will determine the identity of the element
Spin the wheel!
Spin the wheel and earn whatever you land on!
How can the Periodic Table be used to determine the reactivity of an element?
What is: Reactivity, number of shells, number of valence electrons, physical properties like metals, metalloids, and non-metals
Why would two elements in the same group have similar reactivity?
What is: Due to the number of valence electrons
How does the reactivity of elements change from left to right across the Periodic Table?
What is: Going from left to right of the groups, the reactivity will decrease with the exception of group 7 Halogens
What do elements within a group have in common?
What is: Valence electrons
Gold Rush!
Write an arrow for the direction you want to move on and hand it to Mr. Nguyen without other teams knowing what you decided. If no one lands on your spot, you earn the gold, but if more than one person lands on the same spot, no one earns the gold!
How can you use the properties of an element to determine its placement on the Periodic Table?
What is: Valence electrons help with the group, atomic number, atomic mass, periods=number of energy shells, metal, metalloids, and non-metal
What do group and period numbers on the Periodic Table tell you about the atomic structure?
What is: Goups tell you that they react in a similar manner, their reactivity, and the same number of valence electron. Periods tell you the number of energy rings the atom has and how big the atom would be.
