Silver is a chemical element with symbol Ag and atomic number 47. Classified as a transition metal, Silver is a solid at room temperature.
Is silver aqueous or solid?
Silver is a solid at room temperature.
Is Xe in standard state?
Eleven elements are gas in their standard state. All of the noble gases (He, Ne, Ar, Kr, Xe, Rn) as well the halogens flourine and chlorine. Hydrogen, oxygen and nitrogen are the others. All other elements are solid in their standard state.
What is a standard state element?
The standard states of elements are the forms that they adopt at a temperature of 25°C and pressure of 1 atmosphere (1 atm). These forms of the elements are the reactants in the formation equations of multi-element substances. The heat of formation (∆Hf°) of an element in its standard state is zero.
Does silver react to anything?
Silver reacts readily with sulfur or hydrogen sulfide (H2S) to produce silver sulfide (Ag2S), a dark-colored compound familiar as the tarnish on silver coins and other objects. Silver sulfide also forms silver whiskers when silver electrical contacts are used in an atmosphere rich in hydrogen sulfide.
What is Carbon’s standard state?
Graphite and diamond are both forms of elemental carbon, but because graphite is more stable at 1 atm pressure and 25°C, the standard state of carbon is graphite (Figure 1.9. 1). Given enough time, diamond will revert to graphite under these conditions. Hence graphite is the standard state of carbon.

Does silver react with anything?
What are the dangers of silver?
Besides argyria and argyrosis, exposure to soluble silver compounds may produce other toxic effects, including liver and kidney damage, irritation of the eyes, skin, respiratory, and intestinal tract, and changes in blood cells. Metallic silver appears to pose minimal risk to health.
What is enthalpy of diamond?
Carbon occurs in two forms: graphite and diamond. The enthalpy of combustion of graphite is -393.5 kJ, and that of diamond is -395.4 kJ.
