For your first question: graphite won't scratch any of the other itemsAll the other items in the list are harder than graphiteFor 9: (d) tend to lose electrons isn't true - they tend to gain electrons 10: (d) - gold isn't in group 6 12(a) - a noble gas does not readily form compounds 13(d) - tellurium isn't a metalloid; it is in the oxygen family 15(d) - electrostatic atttraction between oppositely charged ions 16(d) - both CO2 and CH4 are covalently bondedHope this answers your questions.
