(Print) Use this randomly generated list as your call list when playing the game. There is no need to say the BINGO column name. Place some kind of mark (like an X, a checkmark, a dot, tally mark, etc) on each cell as you announce it, to keep track. You can also cut out each item, place them in a bag and pull words from the bag.

Density increase down the group
Electrode potential increases down the group (reactivity decreases down the group)
Low density
they conduct heat and electricity less effectively than other metals
Softer and stronger than most other metals (except the alkali metals)
they have high melting points - but mercury is a liquid at room temperature
Very reactive
they react quickly with water, producing hydroxides and hydrogen gas
Ionization Energy decreases going down the group (because the electrons are farther from the core and therefore are easier to remove; Tl does not fit this trend
All group elements are solids except oxygen
their molecules each contain two atoms (they are diatomic)
Electronegativity (the atom's ability of attracting electrons) decreases down the group.
Atomic radius increases down the group (Tl has the largest atomic radius.)
they are usually hard and tough
Melting point increases while going down the group
The noble gases all have low boiling points.
Reactive nonmetals
These elements are widely found on Earth l
their hydroxides and oxides dissolve in water to form alkaline solutions
The boron family adopts oxidation states +3 or +1
React easily with the halogens and water
Atomic radii increase in size down the group.
Four covalent compounds are compounds in which the four electrons in the valence shell play an active role in bonding
