Also, some metal ions display colors that are similar to each other making it hard to tell … Relate your topic to the electromagnetic spectrum. The postulates and limitations of Dalton’s atomic theory are listed below. (Note that one light year = six trillion miles or 6 x 1012 miles). Evaluate. The flame test is an analytical chemistry method used to help identify metal ions. These will be placed into a flame in order to observe the colors produced. We reviewed the safety requirements and lab mechanics. This lesson supports students’ understanding of: Atomic structure; Atomic spectra; Activity series; Time. Evaluate merits and limitations of different models of the atom in relation to relative size, charge, and position of protons, neutrons, and electrons in the atom. FLAME TESTS AND ATOMIC STRUCTURE INTRODUCTION: When sufficient energy is absorbed by atoms, electrons jump from lower quantum levels to quantum levels of higher energy.

Each metallic salt emits a characteristic colored light in the flame. A sodium atom in an unexcited state has the structure 1s 2 2s 2 2p 6 3s 1, but within the flame there will be all sorts of excited states of the electrons. Part One: Flame Tests. These techniques are introduced in the mid of 19th Century during which Bunsen and Kirchhoff showed that the radiation emitted from the flames depends on the characteristic element present in the flame. Atomic structure - (CCEA) Scientists’ ideas about atoms have changed over time. 3.
