What does a Lewis Dot diagram show us?
The number of valence electrons in the outermost shell
300

Find the missing element in the following family:
H, Li, Na, K, Cs, Fr
Rb (Rubidium)

Name two properties of the elements in noble gas family.
(Think: What is their state at room temperature? How many valence electrons? How reactive are they? What is their electronegativity?)
The Noble gases belong to group 8A and have 8 valence electrons. This means that they have a complete outer shell and are therefore not reactive. They are gaseous at room temperature and have no electronegativity.

Heart cells require a certain balance of sodium and potassium ions to function. The blood, which is approximately 83% water, carries these two types of ions to the heart. The property of water that allows it to carry ions to the heart is its __________________.
polarity
400
If a reaction does not change in appearance but does change in composition, what type of change has occurred?
Chemical change
400
What is surface tension?
Surface tension is the tendency of the surface of the liquids to decrease the area
500
What are the lanthanoids and where would you find them on the periodic table?
The lanthanoids (or lanthanide series) are any of the series of 15 consecutive chemical elements in the periodic table from lanthanum to lutetium
500
What is the most reactive group of nonmetals?
WHY are they so reactive?
Halogens; Because they have 7 valence electrons and are close to completing their outer shell.
