The chemical name of the element and its symbol are uniquely tied to the atomic number; thus the symbol "Sr" stands for strontium, whose atoms all have Z = 38. Mass number This is just the sum of the numbers of
Strontium is a yellowish-white alkaline earth metal with atomic number 38 and element symbol Sr. The element is known for producing red flames in fireworks and emergency flares and for its radioactive isotope that is found in nuclear fallout. Here is a collection of strontium element facts. Fas...

The atomic symbol is a one- or two-letter abbreviation of the name of the element. By convention, the first letter of an element’s symbol is always capitalized, while the second letter (if present) is lowercase. Thus, the symbol for hydrogen is H, the symbol for sodium is Na, and ...
One is about the deadly Saint, who is called St or Strontium-90 (somebody points out the symbol for strontium is Sr, not St). The other is about the funny mushroom that grew bigger and bigger. Until it blew up. EDUCATING CHILDREN 1 I have just finished reading what is written on ...
