Place the elements in their proper position on the periodic table. To make this more challenging. I have not included their identities. Instead of the usual chemical symbol, each element is represented by a code letter. Some clues to the element's identities are listed below. In addition, the elements fall into these families or groups.

JKQ, WNVG, IAL, EPFZ, YBR, ODS, CXU, THM

Place each code letter in its proper space in the table below. Indicate the actual chemical symbol that corresponds to each letter.

V is an inert gas

E is an alkali metal

U is a halogen

D is in family VA

J is an alkaline earth metal

T is in family VIA

R has one less proton than A

A has six protons in its nucleus

R has an atomic number one more than J

O has an atomic number one more than A

S has 8 more protons in its nucleus than D

F has only one proton in each atom

Y has atoms that are larger than the atoms of B

I has the largest atomic number in its group

T is found in the fourth period

C has atoms that are larger than those of U, but smaller than those of X

V has one more proton in its nucleus that U

H has the smallest atomic number in its family

G has two protons in each atom

N is a third-period element

Q has an atomic mass greater than that of J and less than that of K

E has an atomic number less than that of Z, but greater than that of J

Z has more protons than other elements in its family

U is found in the second period
