Study Notes
Subatomic Particles
- Electrons are subatomic particles that carry a negative charge.
Protons
- The number of protons in an atom's nucleus is referred to as the atomic number.
Chemical Bonds
- Covalent bonds involve the sharing of electron pairs between atoms, facilitating chemical stability.
Lewis Acid Characteristics
- Lewis acids are substances that can accept an electron pair from a donor, acting as electron pair acceptors in chemical reactions.
Molecular Shape
- A molecule with a steric number of 4 and 2 lone pairs on the central atom has a bent or angular shape, which affects its polarity and reactivity.
Basic Solutions
- Basic solutions have a pH greater than 7, indicating a higher concentration of hydroxide ions (OH⁻) compared to hydrogen ions (H⁺).
