your answer to support each position. (6 marks) Answer: 2. The emission spectrum of an unknown element contains two lines-one in the visible portion of spectrum and the other‚ ultraviolet. Based on Figure 1.1 and on what you have learned about Niels Bohr’s model of atom‚ account for the difference in energy between these lines. (3 marks) Answer: The line which is on the visible portion of spectrum is produced when electron is jumping from higher to lower energy level orbit thus releasing

Lab: Flame Test Purpose: to determine the ID of 2 unknown substances Background Information: Every atom consists of a nucleus with tiny electrons whizzing around it. The further away from the nucleus they are‚ the more energy the electrons have. If a metal atom is heated‚ the electrons get enough energy to jump higher away from the nucleus‚ they become “excited”. When they fall back closer to the nucleus (back to their ground state)‚ they give off this extra energy as light. Why is the

Flame Lab Objective: How an electron absorbs energy and re-emits it as light and why different elements have different spectra. Also to learn how to use flame tests to determine the identity of unknown mixtures. Hypothesis: We know that certain compounds will burn certain flame colors because they emit different wave lengths. Introduction: Neils Bohr made the “Bohr’s Model” in 1922‚ he found that electron travel in specified fields – which‚ when excited‚ will jump to different rings

Development is complex changes including an increase in new skills and abilities such as talking walking writing and smiling. All children are individuals so although they will go through the same stages of development ‚they will not necessarily do so at the same time. As practitioners‚we should not consider any child to be average‚but focus on the child as a whole. There are four stages of human growth patterns. These are childhood(which in four stages is known as Infancy‚early childhood‚ pre
