RULES1. There will be round robin play and all
questions will be all-play.
2. The teams who answers correctly win the point value of the question.
3. If a team answers a daily double incorrectly, then that team will lose the number of points they bid, and other teams can answer correctly to receive the points.
4. There are two daily doubles available. Let’splay

What is the overall charge of a chlorine-35 atom, a chlorine-37 atom, or any isotope? Explain your answer.
“0” (no overall charge) because the number of protons and electrons are equal, so the charges cancel out.

Periodic TableUsing the periodic table, explain why aluminum (Al) is a better choice than magnesium (Mg) or Iron (Fe) for certain real world uses such as boats and house siding.
Aluminum would be less reactive than magnesium since it is a metal located to the right of magnesium on the periodic table. So, it won’t undergo chemical change as readily as magnesium would.
