Day Starter
Objective: Students will interpret and label periodic table trends on a periodic table using the words reactivity, valence electrons, ionization energy, electronegativity.
Question:
1) How many protons, neutrons, and electrons does 1 atom of Carbon contain?
2) What subatomic particle determines the charge on an atom?
3) What is the charge on an atom if it has 12 protons, 13 electrons and 12 neutrons? What is this element?
Exit Ticket
Which element is more reactive, carbon or flourine? Write a perfect 3 sentence paragraph explaining how you know. Use the word valence electrons or atomic radius in your response.
