Chapter 3: Problem 125

Given that one measure of metallic character is the tendency to lose electrons, arrange \(\mathrm{Cs}, \mathrm{Be}, \mathrm{Li}, \mathrm{Ne}\), Na in order of increasing metallic character.

Short Answer

Expert verified
The order of increasing metallic character for the given elements is Ne, Be, Li, Na, and Cs, based on their positions in the periodic table and general periodic trends.

Step by step solution

01

Locate the elements in the periodic table

Start by finding the given elements: Cs, Be, Li, Ne, and Na on the periodic table. Keep in mind their respective groups and periods.
02

Use Periodic Table trends to understand their metallic character

Metallic character tends to increase from right to left across a period and from top to bottom within a group. Elements on the far left within the Alkali metal family (Group 1) are the most metallic and those on the far right within the Noble gas family (Group 18) are the least metallic.
03

Arrange the elements by metallic character

Based on the periodic table trends mentioned above, we can arrange the elements in the increasing order of metallic character. Here are the given elements and their positions in the periodic table: - Cs: Group 1, Period 6 - Be: Group 2, Period 2 - Li: Group 1, Period 2 - Ne: Group 18, Period 2 - Na: Group 1, Period 3 Taking the periodic table trends into consideration, the arrangements in increasing metallic character is: Ne < Be < Li < Na < Cs So, the order of increasing metallic character for the given elements is Ne, Be, Li, Na, and Cs.

Use the elements lithium, potassium, and sodium to explain what is meant by chemical periodicity.

A \(34.01-g\) sample of pure hydrogen peroxide produced at a chemical company contains \(32.00 \mathrm{~g}\) of oxygen. The rest of the mass is due to hydrogen. (a) What is the percent by mass of oxygen and hydrogen in this sample? (b) Another company also produces pure hydrogen peroxide. What is the percent by mass hydrogen and oxygen in its hydrogen peroxide? What chemical law allowed you to answer this question? (c) A \(91.83-\mathrm{g}\) sample of pure hydrogen peroxide is obtained. How many grams of it are oxygen?

Suppose we wanted to use one of the more massive atoms, like \({ }_{92}^{235} \mathrm{U}\), as the standard reference for the atomic mass scale. (a) What would be the universally agreed-upon atomic mass of the \({ }^{235} \mathrm{U}\) isotope? (b) Why don't we use \({ }_{92}^{235} \mathrm{U}\) instead of \({ }_{6}^{12} \mathrm{C}\) ?
