Flag for the Element of Krypton

Flag for the Element of Bromine

Flag of the Element of Arsenic & Selenium

Arsenic is the 33rd element, in the third period so it gets a full center of yellow since yellow is associated with 3.  The red and blue stripes along the top and bottom reflect the numbers 15, and this is the group this element belongs to. The blue central disc with symbol for Arsenic is reflective of the letter P flag, as this element is on the P-Block

Selenium is the 34th element so it gets a yellow and green field reflective of the numbers 3 and 4 for 34.

Flag for the Element of Hydrogen

The Letter H symbolizes Hydrogen.  The colours are ordered to numbers based upon the colour specturm: red is 1, orange is 2, yellow is 3, green is 4, blue is 5, indigo is 6, violet is 7, and black is 8.   Pink fills in for 9, and white is zero. The main background colours coded to the atomic number.  Here the field of white and red represent 01, or 1 proton, which is Hydrogen.  The horizontal stripes on the top and bottom represent the group, which Hydrogen belongs to group 1.  The stripes along the fly and hoist represent the period, which is 1 which is echoed twice on all flags for the atoms.  Finally the central disc has the scientific symbol for the element with colors based upon International Maritime Flags.  In this case since Hydrogen is on S-Block.  The background is white and the central letter is blue.
