Question

3. Evaluate Information Sodium is an example of an alkali metal. The alkoli metals are

found in the leftmost column of the periodic table, known as Group 1. Use the interactive
periodic table to explore the properties of the following alkali metals: lithium (Li), sodium
(No), potassium (K), rubidium (Rb), and cesium (Cs). The animations demonstrate a chemical
property common to alkali metals: they react with water. How does the reactivity vary
among this group of elements? Why might patterns like this be useful to scientists?

Answer 1

Answer: This might be helpful because t is a good basis for organizing elements because each element has a unique number of protons and atomic mass is an indirect way of organizing elements by number of protons.
