alkaline earths halogens Elements with similar chemical behavior are in the same group/family. Elements of Group 1A are. Elements of Group 2A are. Elements of Group 7A are the. Elements of Group 8A are the. noble gases alkali metals Chemistry of the Groups/Families

The alkali metals (Group 1A) - The alkali metals are lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr). - Hydrogen is placed in Group 1 but is not a metal. - The alkali metals react readily with nonmetals to give ions with a +1 charge. - Compounds of alkali metals are common in nature and daily life. Chemistry of the Groups H1H1 Li 3 Na 11 K 19 Rb 37 Cs 55 Fr 87 1

The alkaline earths (Group 2A) - The alkaline earths are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). - All are metals that react readily with nonmetals to give ions with a +2 charge. Chemistry of the Groups Be 4 Ca 20 Sr 38 Ba 56 Ra 88 Mg 12 2

The halogens (Group 17)(Group 7A) - The halogens are fluorine (F), chlorine (Cl), bromine (Br) iodine (  ), and astatine (At). - They react readily with metals to form ions with a  1 charge. Chemistry of the Groups F9F9 Cl 17 Br 35 I 53 At 85 17

The noble gases (Group 18)(Group 8A) - are helium (He), neon (Ne), argon, (Ar), krypton (Kr), xenon (Xe), and radon (Rn); - are monatomic; - are unreactive gases at room temperature and pressure; - are called inert gases. Chemistry of the Groups He 2 Ne 10 Ar 18 Kr 36 Xe 54 Rn 86 18
