Document Summary

Module 3: the periodic table and naming compounds. Elements are arranged into vertical columns called groups (or families) and horizontal rows called periods. Elements in the same group (or family) have similar chemical properties. Elements in a period have different chemical properties. The periods are designated with the numbers 1 to 7. The groups are designated with the numbers 1 to 8 and a letter a or b. The elements in the groups with the letter a are referred to as main-group elements. The elements in the groups with the letter b designation is referred t as the transition elements. The inner transition element (lanthanides and actinides) are located between groups 3b and 4b. Group 2a elements are called alkaline earth metals. Group 8a elements are called noble (or rare, or inert) gases. Organic: compounds that contain at least one carbon atom. Inorganic: compounds that contain atoms other than carbon.

Related Questions

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
