Consider the following energy levels of a hypothetical atom: :E4×−1.71*10^−19J :E3×−7.91*10^−19J :E2×−1.05*10^−18J :E1×−1.75*10^−18J A)What is the wavelength (m)of the photon needed to excite an electron from E1to E4? Round your answer to 3 significant digits. B)What is the energy (in joules) a photon must have in order to excite an electron from E2 to E3? Round your answer to 3 significant digits. C)When an electron drops from the E3 level to the E1 level, the atom is said to undergo emission. Calculate the wavelength (m) of the photon emitted in this process. Round your answer to 3significant digits.

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.
