"An element’s atomic mass is the mass of one atom of that element, measured in atomic mass units (amu). An element’s atomic mass in amu is equal to its molar mass in g/mol." Fuente: BrightStormAtomic ...
"Mixtures are composed of pure substances and elements, but unlike compounds these substances retain their own chemical identities and properties. Mixtures can be homogeneous or heterogeneous. Homogen ...
"Atomic emission spectra are unique spectra of light emitted by an element when electricity is run through it or when it is viewed through a prism. Because they are unique, they can act as an element’ ...
