Periodic Trends in Reactivity Lab. Introduction: The structure of the periodic table is such that elements with similar properties are aligned vertically in columns called "groups". As you will learn in class, this leads to smoothly varying trends in properties such as ionization energy and atomic radius as one moves both down the periodic ...

Lab 4-3 Report Name Periodic Trends of Chemical Reactivitiy Period The Pre-Lab (Purpose, Pre-Lab Questions, Hypothesis, Data Table set-up) is due the day before you plan to conduct the experiment. Purpose Statement: What is the purpose of this lab? Pre-Lab Questions: Answer the following in your OWN words. 1. a.

These demonstrations show the similarity of the physical and chemical properties of the alkali metals and the trend in reactivity down group 1 of the Periodic Table. The experiments take about 10-20 minutes if everything is prepared in advance. Advance preparation includes cutting pieces of alkali metals to the recommended size, filling water ...

Lab Activity: Periodic Trends . Introduction: In this activity, you will model three properties of the elements that show trends across a period and down a group on the periodic table. These properties are: Atomic Radius: a measure of the size of one atom of an element . Ionization Energy: the measure of the energy required to remove an electron from the

Recognizing periodic trends in the physical and chemical properties of the elements is key to understanding the full value of the periodic table. The purpose of this experiment is to identify periodic trends in reactivity and solubility within a group (Group 2) and also across a period (Period 3). In Data Tables A & B, you will compare Mg & Ca ...

The purpose of this experiment is to identify periodic trends in the activity and solubility of the alkaline earth metals. In Part A, the reactions of magnesium, calcium, and ... Post-Lab Questions (Use a separate sheet of paper to answer the following questions.) 1. Which group II metal, magnesium or calcium, is more active? ...

Procedure. Use the measuring cylinder to measure and carefully pour 40 cm 3 of hydrochloric acid solution into each beaker. Into one beaker drop a small piece of magnesium ribbon (5 mm). Into the other, drop a small piece of calcium (5 mm). Compare the reactivity of the two metals.

In this experiment, you will explore these trends in reactivity for the elements. Elements in the Periodic Table are organized by increasing atomic number. As atomic number increases ... Lab #7: Periodic Trends. 2 . Part 2 - Activity Series of Some Metals in HCl . 1. Obtain a small sample of zinc and tin.

Additionally, the Teacher Guide accompanying this activity supplies questions and dialogue intended to support those new to teaching periodic trends and/or new to using guided inquiry-based activities. Figure 1: Blank periodic table for students to use in the Introductory Investigation.

Patterns and Trends. Students study PASCO's Periodic Trend Cards to find patterns that help them reconstruct the periodic table. Supports NGSS Performance Expectation HS-PS1-1: Use the periodic table as a model to predict the relative properties of elements based on the patterns of electrons in the outermost energy level of atoms.

Lab report chem 001a experiment periodic table and periodic law aim: in this experiment we will observe the chemical reactivity of chlorine, bromine and iodine. Skip to document. University; ... Result: A) Periodic Trends in Physical Properties 1. Figure 1. a. As the atomic number of the halogen group increases, the ionisation energy decreases.

Experiment 10 is broken up into five main parts - A. Physical Properties, B. Oxides and Hydroxides of the Elements, C. Reactivity of a Metal Group, D. Reactivity Across a Period, and E. Reactivity of a Non-Metal Group. Each of these parts will demonstrate characteristics and trends of elements on the periodic table.

The Periodic Trends Concept Builder is shown in the iFrame below. There is a small hot spot in the top-left corner. Clicking/tapping the hot spot opens the Concept Builder in full-screen mode. Use the Escape key on a keyboard (or comparable method) to exit from full-screen mode. There is a second hot-spot in the lower-right corner of the iFrame ...

For this part of the experiment you will make a graph of a periodic property vs. atomic number. The property chosen is atomic radius, given in pm (1 pm = 10-12m). The atomic radius, r, is related to the volume of the atom by the formula of a sphere, V = 4/3 r3. In Table 1 below, the atomic radii of the first 54 elements are given.

Periodic Trends Lab. (2) Scientific processes. The student uses scientific practices to solve investigative questions. The student is expected to: (H) organize, analyze, evaluate, make inferences, and predict trends from data; and (I) communicate valid conclusions supported by the data through methods such as lab reports, labeled drawings ...

Lab Activity: Periodic Trends - Atomic Radius. Some properties of elements show repeating patterns on the periodic table. This is called. periodicity. One of these properties is. atomic radius. Atomic radius is the distance from the nucleus of an atom to its outermost electron/orbital. Procedure: For the following data, plot the atomic number ...

Interactive periodic table showing names, electrons, and oxidation states. Visualize trends, 3D orbitals, isotopes, and mix compounds. Fully descriptive writeups.

Investigating Periodic Trends. May 16, 2011. Using Vernier technology to help teach the structure of the Periodic Table may seem strange to some, but not to Jacklyn Bonneau, teacher at the Massachusetts Academy of Math and Science. For years, Jackie has been having her students graph the physical properties of the elements versus atomic number ...

Relationships in the Periodic Table Skyler Scott, Olga Kucherina, Hannah Thomas 03/09/ Chem 004B-QR Professor Sirianni. Introduction: The purpose of this experiment is to explore the similarities and dierence in the properties of the representative elements from Group I, II, II, and VII, and the trend in the acidity or basicity of the oxides of the elements from the third period.

The purpose of this experiment is to identify periodic trends in the activity and solubility of the alkaline earth metals. In Part A, the reactions of magnesium, calcium, and aluminum with water and acids will be compared in order to determine the trend in metal activity within a group (Mg vs. Ca) and across a period (Mg vs. Al) in the periodic ...
