Lab 20: Flame Tests Purpose/Objective: The ground state is the normal electron configuration of atoms or ions in an element. When atoms or ions in ground state are heated to a higher temperature‚ some electrons absorb enough energy to move them to higher energy levels. This is known as the excited state. However‚ the excited configuration is unstable‚ and the electrons must return back to their positions in the lower energy level. As they return‚ the energy that was previously absorbed is now emitted

Reflective report This reflective report has been structured following Gibbs’ (1988) model. Gibbs’ model provides an iterative model of reflection which I am going to use to answer a series of ordered questions: the answer to each question leads onto the next stage of the reflective cycle. Description I will be discussing an incident that occurred while I was on duty in a nursing home where I work as a healthcare assistant. A nurse confronted a carer in an unprofessional manner during handover

Introduction This reflection is based on the psychosis video that I watched on Blackboard. This reflective essay is to provide how my perspective changes and what brings those changes‚ after watching the video and reflecting upon my previous experiences‚ using John’s reflection model. John’s structured reflection model provides chances to healthcare practitioners to reflect upon one’s own lived experiences‚ which brings about a changed perspective and empowerment to achieve effective desirable practice

Particle Motion: Is particle motion is affected by thermal energy? My answer to that question is when thermal energy is added to the substance‚ the particles have increased on energy and move around more‚ but when thermal energy is decreased‚ particles are closer together‚ so they don’t move as much because they are low in energy as well as space. Temperature: The question being asked to answer is if temperature is affected by thermal energy. My answer to that question is its affected because when

Introduction: Electrons are negatively charged subatomic particles found in all atoms. Electrons have particle-wave duality‚ meaning they exhibit characteristics of particles‚ and characteristics of waves. A wave is a periodic function‚ meaning that the function returns to the same value at regular intervals. Also‚ waves have crests and troughs‚ meaning there are repeated local maxima (crests) and minima (troughs). Waves also have a wavelength and frequency. The wavelength is the distance in

This assignment should be a reflection on your experience within the introductory period of practice when caring for a patient. This reflection will help you to understand how this experience has addressed one of your identified learning needs. In this assignment I shall identify and address one of my learning outcomes which has been met on my placement. I shall identify a reflective cycle and explain my reason behind choosing that specific reflective model. One of the learning objectives I set

I have decided to reflect upon the snapping of an umbilical cord during the active management of the third stage in this reflective essay as I wanted to gain a better sense and understanding of the experience (MacDonald‚ 2014). Therefore I have decided to follow the Gibbs model of reflection in which I broke the case down systematically and reviewed it in phases (Lia‚ 2016). By using this model of reflection‚ I was able to recap what happened and how I felt throughout it all and I was able to evaluate
