This is what makes silver potentially deadly in humans. Pure silver is nearly white, lustrous, soft, very ductile, malleable, it is an excellent conductor of heat and electricity. Silver is stable in oxygen and water, but tarnishes when exposed to sulfur compounds in air or water to form a black sulfide layer. Silver, which is a brilliant white lustrous sheen when in its purest state, is also very ductile. How the COVID-19 Pandemic Has Changed Schools and Education in Lasting Ways. Silver. Advantages that silver has over any other metal is that is is very electrically conductive, and also has high heat conductivity. Apart from this, in-depth understanding of the interactions of various silver species (with the biological media) is a probable deciding factor for the synthesis of silver-based drug formulations because the particular form and physico-chemical properties of silver can ultimately decide their antimicrobial action. Silver is a whitish metal that can be polished to a silvery shine. Soluble silver salts, specially AgNO3, are lethal in concentrations of up to 2g (0.070 oz).
