Atomic Structure: Atoms Vs Ions Worksheet Answers
Atoms are the fundamental building blocks of all matter. They are composed of even smaller particles called subatomic particles, which include protons, neutrons, and electrons.
The nucleus is the central core of the atom and contains the protons and neutrons. Protons have a positive electric charge, while neutrons have no electric charge. The electrons are negatively charged and orbit the nucleus in specific energy levels called electron shells.
Nucleus
The nucleus is the most massive part of the atom and contains almost all of its mass. The number of protons in the nucleus determines the element to which the atom belongs.
Electron Shells
Electrons occupy specific energy levels around the nucleus, forming electron shells. The first shell can hold up to two electrons, the second shell can hold up to eight electrons, and so on.
The arrangement of electrons in the electron shells determines the chemical properties of the atom.
Ion Formation
An ion is an atom or molecule that has lost or gained electrons, resulting in a net electric charge. The process of ion formation is called ionization. When an atom loses electrons, it becomes a positively charged ion called a cation.
When an atom gains electrons, it becomes a negatively charged ion called an anion.
The charge of an ion is determined by the number of electrons it has lost or gained. For example, an atom that loses one electron has a charge of +1 and is called a cation. An atom that gains one electron has a charge of -1 and is called an anion.
Types of Ions, Atoms vs ions worksheet answers
There are two main types of ions: cations and anions.

- Cationsare positively charged ions. They are formed when an atom loses one or more electrons.
- Anionsare negatively charged ions. They are formed when an atom gains one or more electrons.
Comparison of Atoms and Ions
Atoms and ions are the fundamental building blocks of matter. They share many similarities, but they also have some key differences. One of the most important differences between atoms and ions is their charge.
Atoms are electrically neutral, meaning they have no overall charge. Ions, on the other hand, have a net electrical charge. This charge can be either positive or negative.
The following table summarizes the key differences between atoms and ions:
| Characteristic | Atom | Ion |
|---|---|---|
| Number of protons | Equal to the atomic number | Equal to the atomic number plus or minus the charge |
| Number of electrons | Equal to the number of protons | Equal to the number of protons plus or minus the charge |
| Number of neutrons | Equal to the mass number minus the atomic number | Equal to the mass number minus the atomic number plus or minus the charge |
| Charge | 0 | Not 0 |
