Purpose: The purpose of this lab was to analyze the trends of the atomic radius (AR) and the first ionization energy (IE) for the first 36 elements of the periodic table. Procedure: A piece of graph paper was given out by the teacher. A periodic table that has the atomic number‚ atomic radius (AR)‚ and first ionization energy (IE) was given out by the teacher. A sheet of paper was taken out to record the elements‚ atomic number‚ atomic radius (AR)‚ and the first ionization energy (IE). To record

Lab: Ionic and Covalent Bonds Objectives • Understand the differences between ionic and covalent bonds. • Connect ionic and covalent bonds with physical properties of matter. Introduction Sugar and salt look so similar that most people cannot tell them apart without tasting them. Chemically‚ white refined table sugar‚ sucrose‚ and salt are very different. An ionic bond between a positive sodium ion and a negative chloride ion creates a molecule of sodiumchloride (NaCl). Covalent bonds between

Reactions in Aqueous Solutions: Metathesis Reactions and Net Ionic Equations Introduction: Metathesis or double decomposition reactions are a reaction in which two compounds react to form two new compounds‚ with no changes in oxidation number. The ions of two compounds exchange partners. AX + BY AY + BX This reaction can occur between two inorganic salts when one product is insoluble in water‚ driving the reaction forward. A typical example is as followed and is considered a molecular equation

Lab Chapter 4 4.1.1 Exercise: Standards are important for NIC‚ Connectors and Media‚ because of the Stability‚ Consistency‚ and Minimization of packet errors. 4.1.2 Exercise: Why is it so low when the capacity for transmission electricity on the copper wire is so high? Because‚ due to truncation on the transmission of voltage with an electric current. 4‚1‚3 Exercise: It’s used in the Healthcare facilities‚ because it’s more fire resistance. 4.1.4 Exercise: Category | Maximum Speed | Application

Lab Report Ionic and Covalent Bonds Lab: Ionic and Covalent Bonds Introduction: The purpose of this experiment was to explore the properties of chemical substances that can be used to identify the types of bonds in a chemical substance using a laboratory procedure. The two types of bonds being identified were ionic and covalent. Based on a substance’s properties‚ how can you determine whether its bonds are ionic or covalent? This is the question I posed before starting the experiment.

production of gametes and spores. Materials: This lab required prepared slides of whitefish blastula‚ onion root tips‚ ovary‚ and testis‚ a microscope‚ and chromosome kit. The prepared slides of whitefish blastula and onion root tips‚ ovary‚ and testis were observed under the 10x and 40x objectives. Mitosis is easily observed in cells that are growing at a rapid pace such as whitefish blastula or onion root tips‚ which was used in this lab experiment. The root tips contain and area called

Lab RepoRt assistant This document is not meant to be a substitute for a formal laboratory report. The Lab Report Assistant is simply a summary of the experiment’s questions‚ diagrams if needed‚ and data tables that should be addressed in a formal lab report. The intent is to facilitate student’s writing of lab reports by providing this information in an editable file which can be sent to an instructor. Exercise

Writing ionic equations for redox reactions You can split the ionic equation into two parts‚ and look at it from the point of view of the magnesium and of the copper(II) ions separately. This shows clearly that the magnesium has lost two electrons‚ and the copper(II) ions have gained them. These two equations are described as "electron-half-equations" or "half-equations" or "ionic-half-equations" or "half-reactions" - lots of variations all meaning exactly the same thing!

How do ionic bonds form? Transferring the electron forms an ionic bond. After transferring the electron‚ the two atoms become ion n will attract together because they have the opposite charges. Then an ionic bond is formed. How do covalent bonds form? A covalent bond is for sharing of electrons. I remember it like co-existing electrons to share (Eg H20). It is usually between two non-metals. Which compound‚ sugar or salt‚ is a better conductor of electricity? Explain your answer. Salt
