The alkaline earth metals are in the second column of the periodic table. This column corresponds to the s subshell being filled with 2 electrons. Therefore, the valence shell electron configuration is ns2. The electron configuration of carbon is 1 s2 2 s2 2 p2. Its valence shell electron configuration is 2 s2 2 p2.

Non-Metals In The Periodic Table. Non-metals can be easily located on the Periodic Table because they are to the right of the line that looks like a stepping ladder. The only exception to this is atomic number 1, Hydrogen (H), which has a different location on the table. Non-metals are characterized by having the exact opposite properties of metals.

Group 1 elements are often referred to as the "alkali metals". The chemistry of sodium is dominated by the +1 ion Na +. You can buy this periodic table poster and more at the WebElements periodic table shop. On 1 May 2014 a paper published in Phys. Rev. Lett by J. Khuyagbaatar and others states the superheavy element with atomic number Z = 117 (ununseptium) was produced as an evaporation residue in the 48 Ca and 249 Bk fusion reaction at the gas-filled recoil separator TASCA at GSI Darmstadt, Germany. A modern periodic table arranges the elements in increasing order of their atomic numbers and groups atoms with similar properties in the same vertical column (Figure 2). Each box represents an element and contains its atomic number, symbol, average atomic mass, and (sometimes) name.

The first 10 elements are as follows- Hydrogen (H), Helium (He), Lithium (Li), Beryllium (Be), Boron (B), Carbon (C), Nitrogen (N), Oxygen (O), Fluorine (F), Neon (Ne). Mnemonic: Happy Henry Likes Beans Brownies and Chocolates Nuts Over Friday’s News. Group 1 and Group 2 elements are collectively called as s-block elements.

Each element has a fixed position on the Periodic Table. The elements are arranged in order of increasing atomic number, with the lightest element (hydrogen: H) in the top left hand corner. An element's position on the Periodic Table tells us whether it is a metal, a non-metal or a semi-metal.
