Concept Introduction:
Atoms are composed of three types of particles called subatomic particles. They are as follows:
- Protons: Positively charged particles in an atom.
- Neutrons: Neutral charged particles in an atom.
- Electrons: Negatively charged particles in an atom.
The neutral atom has equal number of protons and electrons. Gaining or loosing of electrons of an atom forms ion.
Negative charged ions are formed by gaining one or more electrons and it has more electrons than protons.
Positive charged ions are formed by losing one or more electrons and it has more protons than electrons.
Answer to Problem 4.30EP

Explanation of Solution
The chemical symbol of the potassium element is
One electron is lesser than the number protons means it lost one electron and the charge of the potassium ion is
Hence, the symbol of potassium ion

Now we will talk about when an atom is not neutral. This is called an ION. Ions occur when the protons and electrons are not equal. On the Atom Module, I want you to create Beryllium with a mass number of 9 but only add 2 electrons. HoW many electrons would need to be added if the atom was neutral? What is the charge of the ion when you only have 2 electrons? How is the charge determined? 9. Now go to the Symbol Module and create the same atom. Write down the atomic notation for the ion. 10. Using either the Atom or Symbol Modules, create an Oxygen ion that has a -2 charge and a mass number of 18. Determine the number of protons, electrons, and neutrons in the ion. 11. If you want to create a positive ion does the number of protons or electrons have to be greater? If you want to create a negative ion does the number of protons or electrons have to be greater? 12. The number of protons is always the same as the atomic number for the atom and can NEVER change. Therefore, ions are…arrow_forward
