Study Notes
Atomic Structure
- An atom is the smallest unit of a chemical element that retains the properties of that element.
- A neutron carries no charge, it is neutral.
Atomic Number and Elements
- The atomic number refers to the number of protons in the nucleus of an atom, which determines the chemical element.
- Major elements for form and function in the human body include Carbon, Oxygen, Nitrogen, and Hydrogen.
Isotopes
- Isotopes are atoms of the same element that have the same number of protons (atomic number) but a different number of neutrons.
Atomic Orbitals
- An atom with a single electron in its outermost orbital is called an alkali metal.
Chemical Bonding
- Nitrogen (N) typically forms three bonds based on its atomic number.
- A hydrogen bond forms between the hydrogen atom in one polar bond and an oxygen or nitrogen atom in another polar bond.
- Atoms with a net electric charge due to the gain or loss of one or more electrons are called ions.
- Covalent bonds form between atoms when they share one or more pairs of electrons to achieve a more stable electronic configuration.
