Berikut adalah tabel unsur kimia yang disusun berdasarkan nomor atom dan kode warna menurut tipe unsur. Setiap unsur ditampilkan informasi mengenai nama unsur, lambang unsur, golongan dan periode, massa atom (atau isotop yang paling stabil), massa jenis, titik lebur, titik didih dan penemunya. The Manitoba Archival Information Information Network (MAIN) is powered by Access to Memory (AtoM) software. The AMA provides training sessions where members are instructed on how to enter archival descriptions, authority records, and uploading digital objects to MAIN.

LESSON 1: Basic Chemistry

This lesson will introduce you the student to basic chemistry principles. An understanding of this basic information will allow you to learn the more advanced topics in your course lectures.
This lesson focuses on a number of areas related to basic Chemistry. You should review each page in order as they build upon one another. Many of these topics will be review. Others may be new to you. Either way you will learn the fundamentals of chemistry needed in this course.

ATOMS AND IONS

Atoms

Atoms are the basic unit of chemistry. They consist of 3 smaller things:

Protons - these are positively charged (+)
Electrons - these are negatively charged (-)
Neutrons - these have no charge

These 3 smaller particles are arranged in a particular way. In the center is the Nucleus where you find the positive Protons and neutral Neutrons.

In orbit around the nucleus are the Electrons. These are found in a series of orbits (depending on the atom) with differing numbers of electrons as seen below.

Interaction of Atoms

It's the electrons in orbit around the nucleus that allow one atom to interact with other atoms so they can be linked together.

For example, H2O consists of an Oxygen atom linked to 2 Hydrogen atoms. The linkage or interaction between the electrons of the Hydrogen and Oxygen atoms is called a Chemical Bond. More on these later.

Atoms in the Human Body

The human body is made up of a couple dollars worth of chemicals.

The 12 most useful atoms for you to know about are listed below:

Ions

Sometimes atoms gain or lose electrons. The atom then loses or gains a 'negative' charge. These atoms are then called ions.

Positive Ion - Occurs when an atom loses an electron (negative charge) it has more protons than electrons.

Negative Ion - Occurs when an atom gains an electron (negative charge) it will have more electrons than protons.

The following image shows Na losing an electron and Cl gaining an electron

Thus the Na becomes Na+
The Cl becomes Cl-

Here are some examples of common ions:
Na+	Sodium
K+	Potassium
Cl-	Chloride
Ca+	Calcium
Fe+	Iron
P-	Phosphorous
