A sample containing 12c, 160, and an unknown isotope is analyzed in a mass spectrometer. As in the figure, the ions move around a semicircle before striking a photographic plate. The 12ct and 160+ ions are separated by 6.380 cm on the plate, and the unknown isotope strikes the plate 3.610 cm from the 12C+ ions. What is the mass of the unknown element?

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.
