This bingo card has a free space and 24 words: Very reactive, their hydroxides and oxides dissolve in water to form alkaline solutions, React easily with the halogens and water, Softer and stronger than most other metals (except the alkali metals), Electronegativity (the atom's ability of attracting electrons) decreases down the group., they are usually hard and tough, The boron family adopts oxidation states +3 or +1, 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, These elements are widely found on Earth l, they conduct heat and electricity less effectively than other metals, Four covalent compounds are compounds in which the four electrons in the valence shell play an active role in bonding, Atomic radii increase in size down the group., All group elements are solids except oxygen, Density increase down the group, their molecules each contain two atoms (they are diatomic), Reactive nonmetals, They are odorless, The noble gases all have low boiling points., they react quickly with water, producing hydroxides and hydrogen gas, Low density, they have high melting points - but mercury is a liquid at room temperature, Electrode potential increases down the group (reactivity decreases down the group), Melting point increases while going down the group and Atomic radius increases down the group (Tl has the largest atomic radius.).
