Topics of this game:
- Valence electrons are the electrons found on which shell in an atom?
- In an electron dot diagram, what do the dots that surround the element symbol represent?
- How many electrons can the first electron shell hold?
- How many electrons can any shell besides the first electron shell hold?
- How many valence electrons do most atoms need to become stable? (Not including Hydrogen and Helium)
- How many valence electrons do Hydrogen and Helium need to be stable? (Hint: They only have 1 electron shell)
- Which group in the periodic table contains elements that are the MOST stable?
- Which group in the periodic table contains elements that are the LEAST stable?
- Would an atom that has a high number of electron shells and a low number of valence electrons be very reactive or not reactive?
- How many valence electrons do the elements in Group 15 have?
- How many valence electrons does Hydrogen (H) have?
- How many valence electrons does Boron (B) have?
- How many valence electrons does Argon (Ar) have?
- If you were to draw an electron dot diagram of Flourine (F), how many dots would you draw around the element symbol?
