Below is a screen reader searchable table version of the data provided. Use your screen reader's search to skip to a row by searching with the word element, a space, and then either the element's atomic number, symbol, or name. Example: "Element 72" or "Element hafnium" or "Element Hf".

Screen reader searchable periodic table, containing the element number, symbol and name, atomic mass, phase, group (both IUPAC and CAS), Phase at 25 degrees Celsius, and element type. Use your screen reader's search to skip to a row by searching with the word element, a space, and then either the element's atomic number, symbol, or name. Example: "Element 72" or "Element hafnium" or "Element Hf" This is a searchable table and has a screen reader only search content field at the beginning of each row. Use your screen reader find functionality to search and find rows on the table.
