Why Sr hazardous to people?
Sr - strontium, is a highly reactive alkaline earth. It can react with moisture on the skin and other body parts to produce a very strong alkaline substance which will burn the skin. It is more reactive than calcium metal. It is also classed as a heavy metal.
Which element would be most reactive be sr or ba?
Down a group the reactivity increases. So, barium (Ba) is more reactive than strontium (Sr).
What element is more active Sr or Ag?
Sr (strontium) is considerably more reactive than Ag (silver). In fact, Strontium is so reactive that it must be stored in mineral oil to prevent its reaction with the oxygen in the air. Strontium also reacts with water.
What does the abbreviation SR refer to in chemistry?
Sr is the abbreviation for Strontium - a chemical element (symbolSr and atomic number38). An alkaline earth metal, strontium is a soft silver-white or yellowish metallic element that is highly reactive chemically.
Is the element Sb an alkali metal?
No, the element antimony is a member of group 15 with nitrogen, phosphorus, arsenic and bismuth. It is a semi-metal. You may be thinking of Sr, strontium, which is a highly reactive member of the alkali metals.
