Metals and Halogens reactions Elements such as fluorine‚ chlorine‚ bromine‚ iodine‚ and astatine belong to Group 7‚ Halogens. At room temperature‚ fluorine is a yellow gas‚ chlorine is a pale green gas‚ bromine is a red liquid‚ and iodine is a purple solid. Astatine is a radioactive element‚ therefore it exists only in small amounts. All the halogens exist in diatomic molecules. They have high ionization energies and are the most electronegative elements. Their electron configuration ns2 np5 make

Abstract This report is to highlight the methods‚ results and theory relevant during an engineering experiment called “cold rolling of metals". The purpose of this report is to show how readings obtained from the set-out experiment‚ can be evaluated to determine the behavior of 3 selected materials; Brass‚ Copper and Aluminium through the process of cold rolling. The form of the materials are in small strips which are processed via cold-rolling method 4 times from their original state to evaluate

Discussion 1a “Young public leaders are usually less effective because they have so little experience.” Take a position on the statement‚ and state your position. Answer I do not believe public leaders are less effective due to their youth. Typically‚ young leaders bring a sense of newness and hope of change to the public sector. They are more prone to studying their predecessors and expounding only upon what ideas worked‚ rather than continuing a legacy of past leadership. Moreover‚ young leaders’

ATLAS METAL COMPANY CASE Executive Summary The purpose of this report is to help a financial special assistant‚ Linda‚ to analyze the financial position of Atlas Metals Company and deciding its capital budgeting and capital structure. Firstly‚ I explain why firm should use Net Present Value (NPV) methods for capital budgeting rather than Return on Investment (ROI) method and Payback Period method. Secondly‚ I calculate the Weighted Average Cost of Capital (WACC) which will be used as discount rate

the identity of the metals‚ I was capable of deducing a definite‚ possible identity for the golden metal‚ however‚ I could not provide a definite‚ possible identity for the silver metal. Conversely‚ the results of the experiment themselves‚ whether volume‚ mass‚ or density‚ proved insufficient in my attempts to distinguish the identities of the metals. Thus‚ during the experiment‚ I also observed the color of the metals‚ and used these observations in my assessment of the metals. The five trials for

Chemistry Practical: Activity Series of Metals Introduction: The chemical activity of a metal is directly related to its practical use. In this investigation you will investigate the chemical activity of metals with oxygen‚ water‚ acid and alkali‚ to rank metals in order of their activity. Aim: To observe the reactivity of metals in order to determine the activity series of metals. Risk Assessment: In this investigation‚ hydrochloric acid solution is used which is toxic by all routes of

ALKALINE EARTH METALS what are alkaline earth metals? Alkaline earth metals are elements that are in the second group of the periodic table. the elements have two electrons on the outermost shell. the elements include Beryllium‚ magnesseum‚ calcium‚strontium‚ barium and Radium.The alkaline earth metals are all silvercolored and soft‚ and have relatively low densities‚ melting points‚ and boiling points. In chemical terms‚ all of the alkaline metals react with the halogens to form the alkaline earth metal halides

As a form of metal detecting‚ beach metal detecting has grown immensely in popularity over recent years. Not only is it a fun‚ healthy‚ outdoor activity but with more and more people on public beaches these days it can be profitable as well. Here are some basic tips to help you enjoy and profit from detecting on the beach and sand: TIP #1 While all-round detectors have led good finds‚ to be really successful in beach metal detecting you need a specialized detector. Using normal metal detectors make
