question 4 (0.5 points) give the best systematic name for the compound ni3n2 __1__ __2__ a. trinickel b. nickel c. nickel (iii) d. nickel (ii) e. dinitride f. nitride g. nitrogen h. nike
Answer
Brief Explanations:
In naming ionic compounds, the metal is named first with its oxidation state in Roman numerals in parentheses if it has variable oxidation states. Nickel can have different oxidation states. For $Ni_3N_2$, nitrogen has an oxidation state of - 3. Using the criss - cross method in reverse, if there are 2 nitrogen atoms with a total negative charge of -6, and 3 nickel atoms, each nickel atom has an oxidation state of +2. The non - metal is named second with the ending 'ide'. So the name is nickel(II) nitride.
Answer:
- D. nickel (II)
- F. nitride
