(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.

All group elements are solids except oxygen
Density increase down the group
they conduct heat and electricity less effectively than other metals
Very reactive
The noble gases all have low boiling points.
Electrode potential increases down the group (reactivity decreases down the group)
their molecules each contain two atoms (they are diatomic)
The boron family adopts oxidation states +3 or +1
their hydroxides and oxides dissolve in water to form alkaline solutions
Low density
Four covalent compounds are compounds in which the four electrons in the valence shell play an active role in bonding
they are usually hard and tough
Atomic radii increase in size down the group.
They are odorless
Melting point increases while going down the group
they react quickly with water, producing hydroxides and hydrogen gas
Atomic radius increases down the group (Tl has the largest atomic radius.)
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
Reactive nonmetals
React easily with the halogens and water
they have high melting points - but mercury is a liquid at room temperature
Electronegativity (the atom's ability of attracting electrons) decreases down the group.
These elements are widely found on Earth l
Softer and stronger than most other metals (except the alkali metals)
