receiver that receives radio waves from the satellites in orbit‚ which keeps track of how far away each satellite is. In general there are normally 8 or so satellites "visible" to a GPS hand-held receiver at any given moment. Each satellite contains an atomic clock. The satellites send radio wave signals to the GPS receivers so that the receivers can find out how far away each satellite is at a given time. From this‚ the receiver is able to work out how far it is from the satellite. Since we know how fast

PASTE INTO A WORD DOCUMENT 1. What information would you need to calculate the atomic mass of an atom? The atomic number‚ the number of neutrons and add the numbers together. This is the atomic mass. 2. What information would you need to determine the atomic number of an atom? The number of protons in the nucleus of the atom. 3. Chlorine (Cl) has 17 electrons‚ 17 protons‚ and 18 neutrons what is the atomic mass of Cl? 34 4. What is the charge of the above Cl atom? Neutral If it gains

arranging the elements in ascending order of atomic weight and grouping them by similarity of properties. He predicted the existence and properties of new elements and pointed out accepted atomic weights that were in error. By arranging all of the 63 elements then known by their atomic weights‚ he managed to organize them into groups possessing similar properties. He constructed the tables by listing the elements in rows or columns in order of atomic weight and starting a new row or column when

this paper are atomic mass‚ atomic radius‚ first ionization energy‚ and electronegativity. When you study a normal/ordinary periodic table‚ the atomic mass will usually get bigger when going left to right and it will also get bigger when you go top to bottom. The atomic mass gets bigger left to right and top to bottom because the protons‚ electrons‚ and neutrons are increasing making the mass get bigger as you movie along the periodic table. When you look at the trends of the atomic radius‚ you

scientists and philosophers hundreds even thousands of years to come up with an accurate atomic theory. For nearly 2‚000 years science was unable to come up with experiments that were able to test and put forth the theories made up by Democritus which was a fifth century B.C. Greek philosopher. In 1803‚ John Dalton‚ who viewed the atom as a small solid sphere‚ and is credited for the developing of the first coherent atomic theory was now in the picture. This all led to the the first periodic table of the

atom. Atomic Notation Chemical symbols such as C for carbon‚ H for hydrogen‚ and Cs for cesium are used to identify each type of atom. The atomic number of the element is designated as Z and the mass number is designated as A. The atomic number is always equal to the number of protons in the atom. The mass number is equal to the sum of the number of protons and number of neutrons. The mass number (A) is always written as a superscript‚ as in 14C (carbon-14) or as C-14. The atomic number is

Titanium is a silver‚ lustre‚ low in density but is a strong metal. This metal forms a passive but protective oxide coating when exposed to elevated temperatures in air but at room temperatures it resists tarnishing. The most noted chemical property of Titanium is its excellent resistant

bEAN BAG ISOTOPES:ABUNDANCE AND ATOMIC MASS LAB By: Catriona Whalley Partner: Ming Siegel Due: 1.14.10 Prelab A new atomic theory‚ in which all atoms of the same element are identical to one another and equal in mass‚ was proposed by the scientist Dalton. Although the theory had its flaws and was simple‚ it was revolutionary. Scientists became able to study the actual structure and mass of atoms after the discovery of radioactivity. Soon‚ isotopes were discovered‚ as atoms of the same element
