greater understanding of the universe. Specifically‚ we gain better understanding of how the structure of the atom works‚ as we study the interaction of small particles which gives us a better understanding of the world. The data which we have on how electrons and atoms interact is gathered mostly on observations alone. For example‚ the properties of hydrogen atoms can distinguish between the different tissues and muscles within the human body‚ this is because the human body consists of 63% of hydrogen

Sir J.J.THOMSOM is to physics what electron is to an atom. He charged the world of physics with his discoveries and gave momentum to atomic physics. Physics is what today because of this British scientist who is regarded as the greatest experimental physicists of this century. A bookseller’s son‚ Thomsom studied at the Owens College and later at the Manchester University. He wanted to become an engineer‚ but his father’s death in 1872 forced him to study Mathematics‚ Physics and Chemistry as he

Bernal IV-Hydrogen INTRODUCTION Light pollution‚ also known as photopollution or luminous pollution‚ is excessive or obtrusive artificial light. * The International Dark-Sky Association (IDA) defines light pollution as: Any adverse effect of artificial light including sky glow‚ glare‚ light trespass‚ light clutter‚ decreased visibility at night

is to examine the motion of an electron‚ when it encounters a constant magnetic and electric field. We will also observe when the electric field and magnetic field will cancel each other out. This will lead to the electron having no net force acting upon it. By adjusting the values for the magnetic and electric fields‚ we will be able to check the different paths the electron follows. From this data we will be able to calculate the charge-to-mass ratio. Then‚ using the accepted value‚ we can calculate

Structure of Travel and Tourism Assessment 2: Part A: How the Hospitality and Transport sectors have been developed historically? * Hospitality: The historical development of hospitality has been developed for more than2000 years. There are normally 3 different types of hospitality‚ which are: i) hostels ii) motel and iii) hotel. There is also self-camping facility for people staying and living in the campsites. The first early travelers were either warriors or traders or people who

EXPERIMENT: 1 Object: To find the wavelength of Sodium light by Newton’s ring. Apparatus required: A Plano convex lens of large radius of curvature‚ optical arrangement for Newton’s rings‚ plane glass plate; sodium lamp and traveling microscope. Formula used: The wavelength of light is given by the formula λ =D n2+p –Dn2 / 4pR Where D n+p = diameter of (n+p)th ring Dn = diameter of n th ring‚ P = an integer number‚ R = radius of curvature of the curved face of the Plano- convex lens.

DO NOT base your answer on tabulated values since exceptions may occur. | germanium smallest arsenic selenium bromine largest Feedback: Electronegativity is the ability of an atom in a molecule to attract electrons to itself. In general‚ electronegativity increases as the atomic radius decreases. Smaller atoms have higher electronegativities. Notice that all of these elements are in row 4. Across a row of the periodic table‚ atomic radius decreases
