It should include the name of the element (or unknown) examined and the color of the observed flame Identify each unknown from Part One of the lab and briefly explain why you identified each unknown as you did. The first unknown element sodium knew it was because she got yellow and each element corresponded a unique color. The second element potassium knew it was because I acquired a blue color‚ in the experiment verified that each element corresponded to a different color. Part

Nosich’s “The Elements of Reasoning” and Elder’s “The Standards for Thinking” both focus on various techniques people can adopt to become better critical thinkers. According to Nosich‚ two conditions must exist to be considered critical thinking: the thinking must be reflective and it must meet high standards. These two conditions lead us into the eights elements of reasoning presented in the readings. The first element focused on is “Purpose‚” which includes objectives‚ goals‚ your desired outcome

atomic number corresponding to the chemical behavior of that element. Since isotopes have the same number of protons‚ they all have identical chemical behavior. But‚ however‚ since their neutron numbers are different the isotopes of the same element may have different radioactivity. An isotope that is radioactive is called a radioisotope like iodine‚ which is important in our health. In radioactivity‚ the nucleus of an unstable isotope or element breaks down by itself and gives off rays and particles;

may be considered to be among the very first chemical theories‚ such as the theory that all things are composed of air‚ earth‚ fire‚ and water. Each of these were represented by different elements‚ such as sulfur‚ salt‚ mercury‚ and‚ ideally‚ gold. Other ideas held by alchemists were that each of the known elements were represented by heavenly bodies. Gold was earth’s representation of the sun‚ silver for the moon‚ mercury for the planet Mercury‚ copper for Venus‚ iron for Mars‚ tin for Jupiter‚ and
