Tungsten Element Symbol W

W is the chemical element symbol for tungsten, atomic number 74. The same letter is also used for watt and work in other contexts. W identifies the element tungsten in periodic tables and chemical formulas. Its atomic number is 74. For Tungsten Element Symbol, W is encoded as U+0057, and its Unicode name is LATIN CAPITAL LETTER W. The chemical symbol for tungsten is W, and tungsten has atomic number 74. Unlike many two-letter element symbols, W is one capital letter. Its chemistry meaning is established by a periodic table, compound formula, or explicit label. W is a same-glyph notation case. A value such as 60 W normally uses W as the SI unit symbol for watt, while a physics equation may define W as work. In a chemical formula such as WO₃ or WCl₆, neighboring element symbols and subscripts indicate that W stands for tungsten. Those uses should remain on separate pages and should not be merged simply because the character is identical. For chemistry text, keep W uppercase and attach any coefficient, subscript, or charge according to the full formula. “Atomic number 74: W” is an unambiguous lookup example. A standalone W in a mixed technical document should be accompanied by “tungsten” if the domain is not obvious. W is U+0057 LATIN CAPITAL LETTER W. Web authors can use the literal character, the decimal reference W, or the hexadecimal reference W. The encoding does not distinguish tungsten from watt or work; semantic context and labels do that job. Use the Watt Symbol and Work Symbol in Physics pages for those distinct intents. W is the IUPAC chemical symbol for tungsten. The unusual letter comes from the element name wolfram; capitalization is required, and the same letter can have unrelated meanings in other fields.
