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
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.
4.
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.
I am a gas, but I combine very easily with many other elements. I
3. usually form ionic bonds. I frequently form a -1 ion in those ionic
bonds. I am the lightest element in my group.
9.
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.
I am never found alone or unbonded in nature. I most commonly
5. 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.
Although I am in a group of nonmetals, I am found as a solid. If I
7. 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.
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.
Group Element
Elements in my group usually form covalent bonds. We have two
10. fewer valence electrons than noble gases. I am almost twice as heavy
as the lightest element in my group.
