Strontium Symbol Sr

Sr is the IUPAC chemical symbol for strontium, element 38. It is written with capital S followed by lowercase r. The chemistry strings retained here are Sr: strontium, Atomic number 38: Sr, SrCO₃, and Sr²⁺. They show the complete symbol rather than an approximate lookalike. Keep the page’s intent exact. A visual resemblance alone is not enough to substitute another glyph. Frequent failures include writing SR in a chemical formula, confusing Sr with the unit symbol sr, and using Sr as a word abbreviation without definition. For Element with Symbol Sr, confirm that the pasted text still contains Sr and has not been replaced by a visually similar form. For consistent output, apply the following practices: write S uppercase and r lowercase, use Sr only for the element or a clearly defined abbreviation, place ionic charges after the element symbol, and keep the element symbol separate from the unit sr for steradian. The page records HTML decimal S r, HTML hexadecimal S r, and CSS escape 53 72. Test the rendered result because font and emoji presentation can differ. A useful scope question is “Why can Sr look different?” The reviewed answer is: Fonts and emoji platforms draw strontium symbol differently while preserving the same encoded sequence. For manual entry, the retained Windows method is: copy Sr from this page or enter the complete sequence U+0053 U+0072 in a Unicode-aware editor. The macOS method is: open Character Viewer with Control+Command+Space and search for the first character name, or copy Sr from this page. Before publishing, compare the pasted result with U+0053 U+0072, keep a readable label near unfamiliar glyphs, and confirm that the surrounding sentence still expresses the intended element with symbol sr.
