Bonding Characteristics of Atoms (1.1A) You can see that most of the atoms that we have mentioned above are in the first three rows of the periodic table. [graphic 1.2] However, it is their location in a particular column of the periodic table that tells us how many chemical bonds they usually form to other atoms in a molecule.

Periodic Relationships Among the Elements (Periodic Trends) Classification of the elements There are four categories of elements in the Periodic Table (recall Chapter 2) 1. Noble gases, elements in which the outer shell is complete, Group 8A. 2. Representative elements (main group) Groups 1A, 2A, 2B, 3A, 4A, 5A, 6A, and 7A.

( ©2011, bolonc_130819) 2 Fig. 1. The Periodic Table. In the periodic table, the horizontal rows are called periods and the vertical columns are called groups or families.Some of the groups have been given special names. Group 1A elements (Li, Na, K, Rb, Cs & Fr) are called alkali metals.Group 2A elements (Be, Mg, Ca, Sr, Ba, & Ra) are called alkaline earth metals.

H, Li, Na, K, Rb, Cs, Fr are all in group 1A. They have 1 valence electron (on the outer shell or energy level). Period: A horizontal row on the periodic table is called a period. Elements in the same period have the same number of occupied energy levels (highest occupied energy level). Example: Li, Be, B, C, N, O, F , Ne are all in period 2 ...
