Symbol (chemistry) The proton number (atomic number) may be indicated in the left subscript position (e.g., 64Gd). The atomic number is redundant to the chemical element, but is sometimes used to emphasize the change of numbers of nucleons in a nuclear reaction. If necessary, a state of ionization or an excited state may be indicated in the right superscript position (e.g., state of ionization Ca2+).

DERWENT Introduction Derwent Title Terms are used to simplify word searching of Derwent titles, and to optimise the thoroughness of such searches.se of the @ sign (effective from Week 197804) Certain frequently occurring compounds and elements are given an @ sign to indicate the unsubstituted compound or the free or alloyed element. The @ is a part of the search term. Thus PHENOL@ PRODN. refers to the specific compound whereas in HALOGEN-SUBSTD. PHENOL DERIVS.

Strontium Strontium is the chemical element with symbol Sr and atomic number 38. An alkaline earth metal, strontium is a soft silver-white yellowish metallic element that is highly reactive chemically. The metal forms a dark oxide layer when it is exposed to air. Strontium has physical and chemical properties similar to those of its two vertical neighbors in the periodic table, calcium and barium. It occurs naturally mainly in the minerals celestine, strontianite and is mined mostly from the first two of these.

Titanium Titanium is a chemical element with symbol Ti and atomic number 22. It is a lustrous transition metal with a silver color, low density and high strength. It is highly resistant to corrosion in sea water, aqua regia and chlorine.itanium is one of the few elements that burns in pure nitrogen gas, reacting at 800 °C (1,470 °F) to form titanium nitride, which causes embrittlement. Because of its high reactivity toward oxygen, nitrogen and some other gases, titanium filaments are applied in titanium sublimation pumps as scavengers for these gases.
