In a typical fireworks device, the heat of the reaction betweena strong oxidizing agent, such as KClO₄, and an organic com-pound excites certain salts, which emit specific colors. Stron-tium salts have an intense emission at 641 nm, and barium saltshave one at 493 nm. (a) What colors do these emissions pro-duce? (b) What is the energy (in kJ) of these emissions for 5.00 g each of the chloride salts of Sr and Ba? (Assume that allthe heat released is converted to light emitted.)
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.
