Which property of metals describes its ability to transfer heat and electricity?
How would you describe nonmetals?
Conductivity
Nonmetals are poor conductors
What are ions?
atoms with a charge (+ or -)
Which family has elements with a full outer ring?
Noble gases (group 18)
What element has a full outer shell, but does not have 8 valence electrons?
Helium (He)
What do elements in the same period have in common?
Same number of energy levels/electron shells/rings
Which property of metals describes its ability to bend and be pressed thin without breaking?
How would you describe nonmetals?
Malleablility
Nonmetals are usually brittle (breakable)
How do ions form?
atoms lose or gain electrons
Which family has the most reactive metals?
Which element is a nonmetal in the same group as Tin (Sn)?
Carbon (C)
What do elements in the same group have in common?
Same number of valence electrons
Which property of metals describes its shininess?
How would you describe nonmetals apperance?
Luster
Nonmetals are dull, colorless (not shiny)
What are positive ions called?
What are negative ions called?
Cations (+)
Anions (-)

Where are the metals located on the table, generally?
Where are the nonmetals located?
On the left side/left of the metalloids
On the right side/right of the metalloids
How many protons and electrons does an O2- ion have?
What is the ion name/symbol for an atom with 20 protons and 18 electrons?
8 protons, 10 electrons
Ca2+
Which family has 2 electrons in their outer shell?
Alkaline earth metals
Which element is one electron short of being full and is a liquid at room temperature?
As you move across the periods and down the groups, what happens?
Across the periods = add a proton/valence electron
Down the groups = add an energy level/ring
Metals are usually found in what state with the exception of Mercury (Hg) which is typically what?
Nonmetals are usually found in what state? Which ones are not?
Most metals are solid, Mercury is liquid
Most nonmetals are gas; C, P, S, Se, Br, I, (At)
How would you describe the reactivity of alkali metals, halogens, and noble gases?
Alkali metals very reactive (have 1 VE)
Halogens very reactive (have 7 VE, missing 1)
Noble gases are not reactive (full outer shell)
Which family consists of multiple groups, found in the middle of the table?
Transition metals
Which element is in the same group but not the same family as the others? There may be more than one answer.
Why is it located here?
Hydrogen (group 1 nonmetal while the rest are metals but also has 1 valence electron like group 1)
Boron (group 13 metalloid while the rest are metals, but also has 3 valence electrons like group 13)
Astatine (group 17 metalloid while the rest are nonmetals, but also has 7 valence electrons)
