The Atomic Model has changed over time‚ as the years‚ decades‚ and centuries go by we get a better understanding of the atom and what it looks like. The Atomic Model has changed drastically based on the understanding we have on it‚ each new model has added more information to what we know about it‚ making it easier for scientists and the world to understand. The Atomic Model is a very important part of Science and Chemistry‚ it helps explain the structure and what is inside the atom‚ the particle

Historical Development of Atomic Structure Yazan Fahmawi Sept. 30‚ 1995 T3 IBS Chemistry Ms. Redman The idea behind the "atom" goes back to the Ancient Greek society‚ where scientists believed that all matter was made of smaller‚ more fundamental particles called elements. They called these particles atoms‚ meaning "not divisible." Then came the chemists and physicists of the 16th and 17th centuries who discovered various formulae of various salts and water‚ hence discovering the idea of a molecule

causes gravity‚ but the effects have been studied by many physicists and astronomers. Three of the more obvious effects of gravity are things falling down‚ weight‚ and the the moon and planets staying in their orbits. Things fall down. People have generally grown to accept that if one lets go of one ’s prized and valuable textbook when walking through a mud puddle‚ the book will invariably end up in the puddle and therefore be stripped of all value and even legibility. Things fall

destroying our planet? We should think about our earth’s condition day by day because our planet is in great danger. We are very lucky that we can enjoy everything on earth like water‚ air‚ natural resource and others to be enjoyed. Nowadays we all know and realize how important it is to protect our planet‚ but we are mostly too busy or too lazy to make a big change that would improve our lifestyle and save the environment. Many simple ways we can do to take part to conserve our planet such as recycle

of the Solar System A cloud of interstellar gas and/or dust (the "solar nebula") is disturbed and collapses under its own gravity. The disturbance could be‚ for example‚ the shock wave from a nearby supernova. As the cloud collapses‚ it heats up and compresses in the center. It heats enough for the dust to vaporize. The initial collapse is supposed to take less than 100‚000 years. The center compresses enough to become a protostar and the rest of the gas orbits/flows around it. Most of that

We all want to protect our planet‚ but we’re mostly too busy or too lazy to put up big change that would improve our lifestyle and save the environment. We could do many simple habits to implement in our everyday life which will protect our environment such as donate‚ turn off device or walk or cycle. Firstly‚ we could donate our goods. For example‚ if we have tons of clothes or things we want to get rid of

A Comparison of the Planets in the Sol System Shaun J. Sci350 December 19‚ 2004 Introduction Beginning Mercury‚ this paper will compare the nine planets and major moons of our solar system and describe their individual characteristics. At the end of this discussion‚ the habitability factor of these different worlds will be discussed as compared to that of the Earth ’s. A Brief History of the Sol System By radiocarbon dating meteorites‚ we know that roughly 4.6 billion

Lesson 1: Our Solar System What makes up our solar system? When we think of the solar system most of us think of eight planets orbiting around the sun. However‚ the solar system is a lot more complicated‚ larger and exciting than this simple description. The solar system is a gravitationally bound system with all the objects in this system revolving around the sun. The eight planets revolving around the sun are: Mercury‚ Venus‚ Earth‚ Mars‚ Jupitar‚ Saturn‚ Neputune‚ Uranus and Pluto. However‚ the

Atomic Structure & Electricity 1. Draw an atom with an atomic number of 12. Label the protons‚ neutrons‚ and electrons. Use the periodic table to identify which atom you have drawn. 2. How many valence electrons are present in this atom? 2 3. Would this atom prefer to gain or lose electrons? Why? Lose‚ because the octet rule dictates that if there is less than 4 valance electrons‚ they would prefer to leave the atom. 4. Describe the differences between conductors‚ semiconductors
