I have learned from this project is that everyone is original and vary from each other. This was a fun project‚ I got to display who I am and present the things that really mean the most to me‚ and why they are important. Each time I presented to a new person‚ I tried to enthrall them with my own originality. People read my symbols in the way I expected them too because‚ there were very little questions‚ some did have an egregious look on their face when I said I like to dance. If I could do this

INORGANIC CHEMISTRY – CLASS XI (ISC) Properties of Group 1 elements [Alkali metals] 1. Due to high reactivity‚ alkali metals do not occur free in nature. Elements of group 1 (or IA) are known as alkali metals because their hydroxides are soluble in water and form strongly alkaline solutions. Alkali metals are stored under kerosene oil because they get tarnished on exposure to air. 2. The general electron configuration of alkali metals is ns1. 3. Alkali metals have largest size and lowest

Module 2 Exam Review This review is neither a replica of the exam nor does it contain every concept in the module. It is always best practice to review all lessons and assessments. Resubmitting is a great way to review/learn and improve your grade. There are approximately 32 questions (about 3 are essays) on the regular exam; approximately 42 questions (about 5 are essays) on the honors exam. The number in parenthesis is the lesson. None of the honors lessons are in this review. The answer

Eventually they found out the rest of the Atoms over time. Which brings me into the word of Orbital. Orbital is a Neutron‚ electron or a proton Going around a single atom with certain amounts of energy levels. Which are all made up in the Cloud. The cloud is a intense color representing how many atoms are not representing a electron. When you have a
