Elements are arranged from left to right and top to bottom in order of increasing atomic number.

Plus, lithium is on the leftmost group of the Periodic table (group 1), and according to the Periodic trends, the atomic size decreases from left to right in a Periodic table. In other words, the elements which are on the left side of Periodic table have a bigger atomic size.

The periodic table, introduced in Chapter 3 “Atoms, Molecules, and Ions”, lists all the known chemical elements, arranged by atomic number (that is, the number of protons in the nucleus). The periodic table is arguably the best tool in all of science; no other branch of science can summarize its fundamental constituents in such a concise and useful way.

Elements and the periodic table. Elements are the purest form of matter and can not be broken down into any other substance by either a physical or chemical change. There are about 114 elements and they are organized on a modern Periodic Table of the Elements. The Elements are organized by their atomic numbers from top to bottom and left to right.
