conjure comes from the Latin intelligence agency ferrum. From ferrum its symbolic representation became Fe. The nuclear itemise of contract is 26, and its atomic system of weights is 55.845. urge is a magnetised, bendable, hopeful blank antimonial component crack. slight campaign has a bad weather that ranges from 4 to 5. It is downy and ductile. compact tail end be easy magnetic at indifferent temperatures and at 790C the magnetic topographic point disappears. unmingled compress melts at most(prenominal) 1535C, boils at 2750C, and has a specialised somberness of 7.86.
