WHO AM I?

The following chart contains clues about the identities of some of the elements in the Periodic Table.
1.  Read each description and then identify the area of the periodic table in which the element would most likely be
     found.
2.  Fill in the appropriate space in the chart using the name of the group or general category of elements.
3.  In the next column, write the symbol for the possible identity of the element being described.

 

Description

Area

Element

1.

I have a very good 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 member of my group with a one letter symbol.

 

 

2.

I do not conduct electricity and am usually found in the gaseous state.  I do not bond well with other elements.  I can be found in some bulbs and used in signs.

 

 

3.

I am a gas, but I combine very easily with many other elements.  I usually form ionic bonds.  I frequently form a -1 ion in those ionic bonds.  I am the lightest element in my group.

 

 

4.

I am a very tough, durable element.  I can give up two electrons, but sometimes give up more than two when bonding.  I am the main element found in steel.

 

 

5.

I am never found alone or unbonded in nature.  I most commonly form a +2 ion when bonding.  I have the second highest number of protons in my group.

 

 

6.

In my group, the elements are all metals except me.  I have three valence electrons.

 

 

7.

Although I am in a group of nonmetals, I am found as a solid.  If I combine with calcium, two atoms of me, but only one atom of calcium are required.

 

 

8.

I usually form covalent bonds.  I have 5 valence electrons.  I have the highest atomic mass in my group.

 

 

9.

In my group, 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 on the Periodic Table.

 

 

10.

Elements in my group usually form covalent bonds.  We have two fewer valence electrons than noble gases.  I am almost twice as heavy as the lightest element in my group.
