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