Introduction
Atomic structure is the fundamental arrangement of subatomic particles that make up an atom. It is crucial for understanding the behavior and properties of matter.
A worksheet with answers provides a structured framework for students to explore and reinforce their understanding of atomic structure.
Subatomic Particles
Atoms are composed of three fundamental subatomic particles:
- Protons: Positively charged particles located in the nucleus, with a mass of approximately 1 atomic mass unit (amu).
- Neutrons: Neutral particles located in the nucleus, with a mass slightly greater than that of protons.
- Electrons: Negatively charged particles that orbit the nucleus, with a mass negligible compared to protons and neutrons.
Atomic Number and Mass Number
The atomic number is the number of protons in an atom’s nucleus. It uniquely identifies the element and determines its chemical properties.
The mass number is the total number of protons and neutrons in an atom’s nucleus. It provides an estimate of the atom’s mass.
Isotopes
Isotopes are atoms of the same element that have different numbers of neutrons. They have the same atomic number but different mass numbers.
Isotopes are used in various applications, such as radioactive dating, medical imaging, and nuclear energy.
Electron Configuration
Electron configuration describes the arrangement of electrons in the atomic orbitals around the nucleus.
Rules for writing electron configurations include:
- Aufbau principle: Electrons occupy the lowest energy orbitals first.
- Pauli exclusion principle: No two electrons can have the same set of quantum numbers.
- Hund’s rule: Electrons occupy degenerate orbitals with the same spin before pairing.
Periodic Table
The periodic table is an organized arrangement of elements based on their atomic numbers and electron configurations.
The periodic table allows us to predict the properties of elements based on their position in the table.
