Summary
Chemistry resources help students understand atoms and elements. Study the properties of atoms and how they form elements. Common elements and the concepts of atomic number, isotopes, and bonding are covered.
Properties of elements
Elements have specific properties. This part explains what makes an element an element. The atomic number of an element is defined and how it helps understand the arrangement of electrons in an atom. The distribution of electrons in phosphorus is an example.
Elements most common in living matter
The most common elements in living matter are explained. This part asks questions about which elements are most common. The combinations of elements in the human body are given. The four elements that make up approximately 96% of living matter are listed.
Atomic structure and bonding
The structure of atoms is described, including protons, neutrons, and electrons. Isotopes and radioactive decay are covered. The different types of bonding between atoms are explained, including covalent, ionic, and hydrogen bonds. Each type of bond is explained, including why water molecules are attracted to each other.
Key terms
- Atomic number
- The number of protons in an atom's nucleus.
- Isotopes
- Atoms of the same element with different numbers of neutrons.
- Ionic bond
- A bond resulting from the transfer of electrons between atoms.
- Hydrogen bond
- A bond between the hydrogen of one water molecule and the oxygen of another.
- Covalent bond
- A bond resulting from the sharing of electrons between atoms.
- Polar covalent bond
- A bond resulting from an unequal sharing of electrons between atoms.
