Study Notes
- The text discusses the topic of chemical bonding and its different types: ionic and covalent.
- Metals, non-metals, and metalloids are identified using the periodic table of elements. Metals are red, non-metals are blue, and metalloids are yellow.
- Table salt (sodium chloride) is an example of an ionic compound, formed when a metal atom (sodium) transfers its valence electron to a non-metal atom (chlorine).
- Valence electrons are found in an atom's outermost shell and can be determined by the group number in the periodic table.
- Ionic bonding occurs between a metal and non-metal when there is a complete transfer and gaining of electrons.
- Covalent bonding, also known as molecular bonding, occurs when atoms share electron pairs.
- Covalent bonding commonly occurs between non-metals and results in stable compounds.
- Covalent bonding can be non-polar (electrons shared equally) or polar (electrons shared unequally).
- Properties of ionic compounds include solid state existence, low conductivity, hardness, high melting and boiling points, and insolubility in organic solvents.
- Properties of covalent compounds include existence as solid, liquid, and gas states, low conductivity, flexibility, lower melting and boiling points, and solubility in organic solvents.
- Ionic compounds exist only in the solid state, while covalent compounds exist as solid, liquid, and gas.
- Ionic compounds have low conductivity, while covalent compounds have very low conductivity.
- Ionic compounds are very hard or brittle and have higher melting and boiling points than covalent compounds.
- Both ionic and covalent compounds are not malleable and not ductile.
- Ionic compounds are soluble in water but insoluble in organic solvents, while covalent compounds are insoluble in water but soluble in organic solvents.
