particle of an element that retains the characteristics of that element. Each of the known 118 elements has atoms that are different from the atoms of all other elements. This gives each element a unique atomic structure. According to the classical Bohr model‚ atoms have a planetary type of structure that consists of a central nucleus surrounded by orbiting electrons‚ as illustrated in Figure 1–1. The nucleusconsists of positively charged particles called protonsand uncharged particles called neutrons

Empirical and Molecular Formula | Key Concepts * Empirical Formula of a compound shows the ratio of elements present in a compound. * Molecular Formula of a compound shows how many atoms of each element are present in a molecule of the compound. * The empirical formula mass of a compound refers to the sum of the atomic masses of the elements present in the empirical formula. * The Molecular Mass (formula mass‚ formula weight or molecular weight) of a compound is a multiple of the empirical

mechanisms that regulate cellular senescence‚ organismal ageing‚ and species-specific lifespan depend on a synergy of pathways that are multifactorial and extremely complex‚ though not yet completely understood. Recently‚ the development of new molecular techniques has elucidated‚ at least in part‚ the primary pathways involved in ageing. In parallel with the search to uncover the factors that control ageing is the endeavor to discover methods of extending lifespan‚ in hopes of living both youthfully

Kinetic Molecular Theory Basic Concepts The gas laws developed by Boyle‚ Charles‚ and Gay-Lussac are based upon empirical observations and describe the behavior of a gas in macroscopic terms‚ that is‚ in terms of properties that a person can directly observe and experience. An alternative approach to understanding the behavior of a gas is to begin with the atomic theory‚ which states that all substances are composed of a large number of very small particles (molecules or atoms). In principle‚ the

MODELING LEACHATE MIGRATION FROM A LANDFILL December‚ 2003 1 INTRODUCTION A two-dimensional‚ steady state transport modeling using MODFLOW/CTRAN was carried out following the particle tracking calculations to simulate potential contamination for leachate migration from Gibraltar landfill. Gibraltar landfill was a disposal waste site in Bogotá (Colombia) until 1988. The site presented problems related to contamination for leachate migration after its closure‚ since the operation

Electronic Literature Pedagogy: A Questionable Approach by: Chris Mott WHY SHOULD I TEACH ELECTRONIC LITERATURE? The first reason to teach electronic literature is practical: digital media are the most rapidly growing forms of communication‚ and they will only grow in their influence and pervasiveness. Most of our students are fairly skillful with electronic technology‚ but as we all know‚ skill is not literacy. Literacy includes the ability not only to perform in a given medium‚ but to think
