Atoms, Ions and Isotopes
- Describe the position, mass and charge of protons, neutrons and electrons. Describe the electron arrangements for the first 20 elements. Calculate the number of neutrons, protons and electrons for an atom or ion given the mass number of the isotope and the charge of the ion. Calculate the average atomic mass from isotopic data. (E2)
Periodic Table
- Classify elements as metal, non-metal, or metalloid and locate them on the periodic table
Identify trends in properties such as melting point, ionization energy, atomic radius, chemical reactivity, ion charge, and conductivity
Identify the following families of elements and describe their properties: alkali metals, alkaline earth metals, halogens, noble gases, transition metals.
Predict the characteristics of elements knowing the characteristics of another element in that family
Predict the formulae of compounds given the formula of another compounds containing elements in the same families
Predict the probable electron gain or loss for elements in columns 1,2,13,15,16 and 17 (E4/5)
Chemical Bonds
- Describe ionic bonding, covalent bonding, London Forces. Explain the connection between bonding and valence electrons. Draw an electron dot diagram for an atom, ion or molecule. (E6/7)
