Atoms: Building Blocks of Minerals

Study Notes

Atomic Structure

Atoms are the smallest particles of an element.
The nucleus, located at the center of an atom, contains positively charged protons and usually uncharged neutrons.
Negatively charged electrons orbit the nucleus.

Elements and Classification

Atomic number is defined as the number of protons in an element.
Elements are characterized by their atomic number, determining their unique identity.
Approximately 90 naturally occurring elements exist, with 23 having been synthesized.
The periodic table organizes elements by grouping those with similar properties in vertical columns.

Atomic Mass Number and Isotopes

Atomic mass number is the total of protons and neutrons in the atomic nucleus.
Isotopes are variants of atoms that have the same number of protons but differ in the number of neutrons, resulting in different atomic mass numbers.
Differences between isotopes can provide unique applications or benefits, often utilized in various scientific fields.

Applications of Isotopes

Radioactive isotopes, such as carbon-14, are instrumental in dating geological materials and historical events.
