(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.

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