Study Notes
Atomic Structure
- Protons and Neutrons are located in the center of an atom, collectively known as the nucleus.
- The nucleus is the core of the atom, housing protons and neutrons.
Sub-atomic Particles
- Protons are critical for determining the element of the atom.
- Protons and Neutrons are considered "heavy" particles due to their significant mass, while Electrons are "light" with negligible mass.
- Both Protons and Neutrons are influential in determining the atomic mass of an element.
- Electrons play a vital role in the bonding of atoms.
Isotopes and Ions
- An isotope refers to atoms of the same element that differ in the number of neutrons.
- An ion is defined as an atom or molecule that has a net electric charge resulting from the loss or gain of one or more electrons.
Specific Ions and Carbon Isotope
- A sodium ion (Na-) with 11 protons will have 11 electrons, maintaining charge neutrality.
- Carbon, having 6 protons, will also have 6 electrons. In the case of Carbon-14, it contains 6 protons, 6 electrons, and 8 neutrons, due to the additional neutrons contributing to its atomic mass.
