Basic Information:
* Atomic Number: 8 (This means it has 8 protons)
* Atomic Symbol: O
* Atomic Mass: Approximately 16 (This is the total number of protons and neutrons)
Subatomic Particles:
* Protons: 8 positively charged particles located in the nucleus.
* Neutrons: 8 neutral particles located in the nucleus.
* Electrons: 8 negatively charged particles orbiting the nucleus in specific energy levels called electron shells.
Electron Configuration:
* First Shell (K shell): 2 electrons
* Second Shell (L shell): 6 electrons
Visual Representation:
Imagine the nucleus at the center of the atom. The protons and neutrons are tightly packed together in the nucleus. The electrons are distributed in shells (or energy levels) around the nucleus.
* The first shell, closest to the nucleus, can hold up to 2 electrons.
* The second shell can hold up to 8 electrons.
Key Points:
* The number of protons defines the element. All oxygen atoms have 8 protons.
* The number of neutrons can vary slightly, resulting in isotopes of oxygen.
* The outermost electron shell (valence shell) is crucial for determining the atom's chemical reactivity. Oxygen has 6 electrons in its valence shell, meaning it tends to gain 2 electrons to become stable.
