Families of Elements Pre-lab
I. Purpose- The purpose of this lab is to identify elements and observe similarities shared between them.
II. Safety- In this lab the needed safety materials required are safety goggles and apron. Also its suggested to wash hands after dealing with any of the chemicals. some chemicals with safety hazards we will be working with are Sodium chloride with is slightly toxic if ingested. Sodium Bromide which is slightly toxic if inhaled or ingested may cause serious eye damage if in contact. Sodium Iodide may cause serious eye damage, corrosion or irritation causes skin irritation. Silver Nitrate may cause skin corrosion or irritation also may cause severe skin burns and eye damage, very flammable keep away from heat, sparks, open flames, and hot surfaces. Magnesium Nitrate may cause skin and serious eye damage, corrosion or irritation also it is very flammable. Calcium Nitrate Is very reactive and a oxidizer, It will also irritate any contact point. Barium Nitrate and Strontium Nitrate also have similar affects to exposed skin and they are also oxidizers.
III. Pre-Lab Questions- What are the group 1 elements called, they are called alkali metals. List the group one elements, Hydrogen, Lithium, Sodium, potassium, Rubidium, Cesium, and Francium. How many valence electrons does group 1 have, group 1 has 1 valence electron. When group one elements become ions what are is their charge, their charge is +1. What are the group 2 elements called, they are called the alkali earth metals. List the group 2 elements, the group 2 elements are Beryllium, Manganese, Calcium, Strontium, Barium, and Radon. How many valence electrons does group two have, group two has 2 valence electrons. When group two elements become ions what is their charge, their charge is +2. What are the group 17 elements called, they are called the Halogens. List the group 17 elements, Fluorine, Chlorine, Bromine, Iodine, and Astatine. How many valence
