Dmitri Mendeleev developed a chart like arrangement of the elements called the 1 . He stated that if the elements were listed in order of increasing 2 , their properties repeated in a regular manner. He called this the 3 of the elements. The arrangement used today differs from that of Mendeleev in that the elements are arranged in order of increasing 4___. Each horizontal row of elements is called a(n) 5____. Each vertical column is called a(n) 6 , or , because of the resemblance between elements in the same column, a(n) 7 .
In rows 4 through 7, there is a wide central section containing elements, each of which is called a(n) 8 . Rows 6 and 7 also contain two other sets of elements that are listed below the main chart. These are called the 9____ and the 10____, respectively. Each of the elements to the left of the stairstep line of the chart, is classified as a(n) 11 . Each of the elements at the right side of the stairstep line is classified as a(n) 12____. Each of the elements between these two main types, having some properties like one type and other properties like the other type, is called a(n) 13____. Each of the elements in the column labeled IA or 1 is called a(n) 14____. Each of the elements in the column labeled IIA or 2 is called a(n) 15____. Each of the elements in column VIIA or 17 is called a(n) 16____. Each of the elements in column VIIIA or 0 or 18 is called a(n) 17____.

18. I have the ability to conduct electricity. I am never found alone in nature. When I combine with other elements, I usually give up my one valence electron. I am the only element in my group with a 1-letter symbol. Who am I??
19. I do not conduct electricity and am usually found in the gaseous state. I do not bond well with other elements. Some call me snobby. I call myself noble. I can be found in some bulbs used in signs. Who am I??
20. I am a gas, but I combine very easily with many other elements. I usually form ionic bonds. I frequently add one valence electron from my original 7 in those ionic bonds. I am the lightest element in my group. Who am I??
21 .I am a lustrous, a good conductor of electricity, and malleable element. I can give up two electrons, but sometimes I give up more than two when bonding. I am the main element found in steel. My Latin name is Ferrous. Who am I??
22. I am never found alone or unbounded in nature. I most commonly form a +2 ion when bonding because I have two valence electrons to lose. I have the second highest number of protons in my family. Who am I??
23. In my family the elements are all metal accept for me. I have 3 valence electrons. Who am I??
24. Although I am the heaviest in a family of nonmetals, I am found as a solid. I am one valence electron away from being a noble gas. If I combine with calcium, two atoms of me but only one atom of calcium is required. Who am I??
25. I have 4 valence electrons. I like to hang out on steps. I am used to make microchips/computer chips. Who am I??
26. In my family there are nonmetals, metalloids, and metals. I have the same number of protons as the sum of the protons in the two elements directly above me in the periodic table. Who am I??
27. The elements in my family usually form covalent bonds. We have two fewer valence electrons than nobel gases. I am almost twice as heavy as the lightest element in my group. Who am I??
