Chapter 3, Problem 3.49E
Interpretation Introduction

Interpretation:

The trend of density of the metallic elements on moving from left to right across a period of the periodic table is to be predicted.

Concept introduction:

Density is defined as the ratio of mass of a substance to its volume. Mass number is defined as the sum of number of protons and neutrons which are also known as nucleons.

On moving from left to right in a periodic table, the atomic radii decrease. On the other hand, the atomic radii increase from top to bottom.

5.Reason from a scientific model. Write out a brief paragraph explaining why we see specific colors when we heat up ionic salts up in a flame. When providing an explanation, make sure to describe the events in the correct order, and specify correctly the cause of a change and the effect of that cause. Describe the Bohr model of the atom and make sure you address the following questions: So a. What is happening to the atoms in the solid salts as they are heated: a) What phase change occurs as you heat the salt? b) Where is the energy coming from for this phase change? b. What is happening to the electrons inside the metal ions to make them generate visible light? 1. Use a Bohr model of an atom to describe the energy changes of the electron required to generate light, starting from the ground state. Why do different atoms produce different colors? All these atoms have the same number of valence electrons, so why do you think their colors are so different? C.
Please write 1 or 2 pages about “The history of any periodic element”. Please choose one element in the Periodic Table. Your paper you should include Title, Introduction, Discussion, Conclusion and References.
The element belonging to group 15, period 3 is named
