Sodium atoms can be made to emit yellow light at a wavelength of 589.0 nm if they are heated sufficiently in a Bunsen flame. This light is the basis for the test for sodium in qualitative analysis. In the flame the atoms are excited by fast-moving molecules having an average energy per mole of 3RT/2. The temperature at which this occurs is 1500 degrees celsius. Why does it require that temperature?
Atomic Structure
The basic structure of an atom is defined as the component-level of atomic structure of an atom. Precisely speaking an atom consists of three major subatomic particles which are protons, neutrons, and electrons. Many theories have been stated for explaining the structure of an atom.
Shape of the D Orbital
Shapes of orbitals are an approximate representation of boundaries in space for finding electrons occupied in that respective orbital. D orbitals are known to have a clover leaf shape or dumbbell inside where electrons can be found.
