Study Notes
Atomic Properties
- Electronegativity is the ability of an atom to attract electrons in a covalent bond, measuring the atom's ability to pull shared electrons towards itself.
- Electron affinity measures the energy change when an electron is added to a neutral atom, indicating the atom's tendency to gain or lose electrons.
- Atomic radius is the distance from the nucleus of an atom to its outermost electron, determining the size of an atom.
Bonding and Energy
- Ionization energy is the energy required to remove an electron from a neutral atom, indicating the strength of an atom's hold on its electrons.
- Polar covalent bonds result from a difference in electronegativity between atoms, where one atom has a stronger pull on shared electrons, creating a partial positive charge on one atom and a partial negative charge on the other.
