![]() ![]() Beginning at the top left of the table, or period 1, group 1, is a box containing “1 hydrogen H nonmetal gas and 1.008.” There is only one other element box in period 1, group 18, which contains “2 helium H e nonmetal gas and 4.003.” Period 2, group 1 contains “3 lithium L i metal solid and 6.94” Group 2 contains “4 beryllium B e metal solid and 9.012.” Groups 3 through 12 are skipped and group 13 contains “5 boron B metalloid solid 10.81.” Group 14 contains “6 carbon C nonmetal solid and 12.01.” Group 15 contains “7 nitrogen N nonmetal gas and 14.01.” Group 16 contains “8 oxygen O nonmetal gas and 16.00.” Group 17 contains “9 fluorine F nonmetal gas and 19.00.” Group 18 contains “10 neon N e nonmetal gas and 20.18.” Period 3, group 1 contains “11 sodium N a metal solid and 22.99.” Group 2 contains “12 magnesium M g metal solid and 24.31. Each element will be described in this order: atomic number name symbol whether it is a metal, metalloid, or nonmetal whether it is a solid, liquid, or gas and atomic mass. If you click on Og and go to it's PubChem elemental page you see the most stable isotope has a half life of 0.89 millliseconds, and only a few atoms have ever been produced. It is labeled “Symbol.” Below that is the number 1.008 which is labeled “Atomic Mass.” Below that is the word hydrogen which is labeled “name.” The color of the box indicates that it is a nonmetal. If you go to the Pubchem periodic table and click 'standard state, you will see 2 elements are liquid, 11 are gasses, and one (Og) is 'expected' to be a gas. The number 1 is in its upper-left hand corner and is labeled “Atomic number.” The letter “H” is in the middle in red indicating that it is a gas. Label and color code for : Metals, Nonmetals and metalloids. Label and color code the element symbols for solid, liquid, gas and man made. To the left of this box is an enlarged picture of the upper-left most box on the table. Fill in each box with the element name, symbol, atomic weight and atomic number. Sources, facts, uses, scarcity (SRI), podcasts, alchemical symbols, videos and images. Element Iron (Fe), Group 8, Atomic Number 26, d-block, Mass 55.845. Periodic Table of Videos Created by video journalist Brady Haran working with chemists at The University of Nottingham. The 18 columns are labeled “Group” and the 7 rows are labeled “Period.” Below the table to the right is a box labeled “Color Code” with different colors for metals, metalloids, and nonmetals, as well as solids, liquids, and gases. Podcasts Produced by The Naked Scientists. \): Elements in the periodic table are organized according to their properties. ![]()
