this experiment. In particular, observations of similar behavior permits grouping of different elements into chemical families, while noting trends within families allows ordering of elements in each column. These groupings, based on experimental observations, are in agreement with theoretical descriptions of the atom. Epidemiology is the study of the determinants, occurrence, and distribution of health and disease in a defined population. Infection is the replication of organisms in host tissue, which may cause disease. A carrier is an individual with no overt disease who harbors infectious organisms.

In conclusion, the lab demonstrated the periodic trends that occur during reactions between metals and water. The one with the greatest reaction, Sodium, had this reaction because out of the four elements, it had the least amount of effective nuclear charge, stronger shielding forces, and low ionization energy, allowing the valence electrons to be easily removed.  

Students will be able to explain the trends for electronegativity, ionization energy, and atomic size on the Periodic Table by performing an activity, taking notes, and doing practice questions. Ionization energy, electronegativity, and atomic size display characteristic trends on the Periodic Table. Chula Vista, CA. ionization energy. - After completing this lab experiment, I learned that the periodic table is full of patterns and trends, including that elements are placed on the table based on how react with different substances. Powered by Create your own unique website with customizable templates. ○ Understanding the periodic trends allows us to make predictions about the properties of individual elements based on their position on the periodic table. ○ There are some exceptions to the rules of periodic trends.

The periodic table makes rich ground for educational experiments that are also fun and often surprising. Since the elements of the periodic table include everything from the lightest gas known to man to the most dense and heavy metal, and since many of them are found in everyday objects, it's easy to find experiments that will entertain students as they learn about chemistry.
Dec 13, 2013 · In addition to providing an introduction to the 118 elements, Toca Labs lets kids play virtual scientist with elements and experiment with how the elements will react when heated up on a Bunsen burner, cooled down with ice, or combined with the contents of a mystery test tube. This is a fantastic way for kids to learn the periodic table.

The atomic number of an atom is equal to the number of protons in its nucleus.

Periodic table, in full periodic table of the elements, in chemistry, the organized array of all the chemical elements in order of increasing atomic number —i.e., the total number of protons in the atomic nucleus. When the chemical elements are thus arranged, there is a recurring pattern called the “periodic law” in their properties, in ... The periodic table as a list of elements arranged so as to demonstrate trends in their physical and chemical properties. Activities Demonstration of the reaction with water of lithium, sodium and potassium. Periodic trends are patterns in the periodic table for different aspects of a certain element. Major periodic trends include: electronegativity, ionization energy, electron affinity, atomic radius, melting point, and metallic character. They provide chemists with an invaluable tool to quickly predict an element’s properties.

The elements in groups (vertical columns) of the periodic table exhibit similar chemical behavior. This similarity occurs because the members of a group have the same number and distribution of electrons in their valence shells. However, there are also other patterns in chemical properties on the periodic table.

Periodic Trends and Properties of Elements Std 1 (use with Chapter 6) Experimental Overview. The purpose of this experiment is to identify periodic trends in reactivity and solubility of some alkaline earth metals (Group 2). You will also test for trends in Period 3 (row 3). There are three factors that help in the prediction of the trends in the Periodic Table: number of protons in the nucleus, number of shells, and shielding effect. The atomic size increases from the top to the bottom in any group as a result of increases in all of the three factors. These elements have low melting and boiling points, low densities, low ionization energies, and low electronegativity. Other groups share properties much like group 1 does. Another characteristic of the periodic table is that you tend to see trends as you go across a period,...

C4.9c Predict general trends in atomic radius, first ionization energy, and electronegativity of the elements using the periodic table. Specific Lesson Objectives 1. Identify periodic trends and use them to predict properties of elements. 2. Identify the trend in reactivity for the halogens, alkali metals, and alkali earth metals. The concepts and categories that one uses to map reality is one’s metaphysical system. The Periodic Table of the Elements is a metaphysical system. It offers a map of the elements, lining them up into different categories. It is a map that is supported by empirical work, but the map itself is metaphysical in nature. Oct 30, 2013 · Trends of the Periodic Table of Elements Essay 3562 Words | 15 Pages. Trends of the Periodic Table of Elements Introduction The objective of this experiment was to establish trends in the Periodic Table of Elements, involving the characteristics of elements in the same group and/or period. The structure of the table shows periodic trends. The seven rows of the table, called periods, generally have metals on the left and nonmetals on the right. The columns, called groups, contain elements with similar chemical behaviours. discovers atoms have a lot of empty space. gold foil experiment- puts alpha particles through gold foil. Although the vast majority of particles passed right through the foil in approximately 1 in 8000 were deflected; therefore, most of the atom was made up of empty space.
