Answer these questions in complete sentences in your journal.
- One sodium (Na) atom and one chlorine (Cl) atom form a chemical compound called sodium chloride (NaCl or table salt). Keeping in mind that an atom with a full electron shell (8 e-) is a more stable arrangement of electrons, how could Na and Cl interact to form a chemical compound?
- Draw a Lewis diagram showing this interaction (NaCl).
- One lithium (Li) atom and one fluorine (F) atom react chemically to form lithium fluoride (LiF). How could Li and F interact to form a chemical compound (think about electrons again)?
- Draw a Lewis diagram showing this interaction (LiF).
- One beryllium (Be) atom and one oxygen (O) atom form beryllium oxide (BeO). Compared with NaCl or LiF, how is the arrangement of electrons different in this compound?
- When combined as NaCl, LiF, KBr and BeO the outer electron shell of EACH INDIVIDUAL ATOM of those compounds resembles the outer electron shell of what group of elements in the periodic table?
- Given your observations of the patterns occurring when NaCl, LiF, KBr and BeO form, predict the chemical formula for these compounds:
- a compound of rubidium and iodine.
- a compound of magnesium and chlorine.
- a compound of beryllium and fluorine.
- a compound of lithium and oxygen.
