Background + Directions: The symbols below represent fictitious elements. Read the clues.
Then write the symbol of each element in its appropriate box in the periodic table below. When
you finish, you will read a message.
Ic = This neutral element needs only 1 electron, and then its 2nd ring will be noble.
E = This neutral element is the smallest in the column where all atoms make 4 covalent bonds.
W = This neutral element prefers to bond covalently and has only one proton.
Ol = This neutral element has 3 electrons on its 3rd ring.
Is = Of all the elements that can have a charge of +2, this one is the smallest.
R = makes 3 covalent bonds and has 15 protons. It is neutral.
Tu = This element will have a charge of -2 if it gets electrons to complete its 3rd ring.
St = This neutral element has one electron in its 4th ring and will have a (+1 charge) if it loses it.
S = is a medium-sized noble gas.
Th = This neutral element has 3 electrons on its 2nd ring.
N = This element will have a (-1 charge) if it completes its 3rd ring with an electron.
Om = What element is used in combustion? Place “Om” in the same spot as that element.
Ha = This element has 1 complete ring. It is similar to the small king.
En = This neutral element would like to lose 2 electrons to become noble. It has 20 Protons.
At = What real element makes up 79% of the atmosphere? Put “At” in the same location.
G = is the largest noble gas on the chart below.
T = This neutral element has 1 outer electron in its second ring.
Mb = This neutral element wants to donate 2 electrons which are found on its 3rd ring.
Fo = This neutral element is the larger of the two atoms that can make 4 covalent bonds.
Y = This neutral element has 2 complete rings and one extra outer electron in the 3rd.
