Question

Quizplus · Accepted Answer

The correct naming convention for CaSe is calcium selenide. This is because calcium has a 2+ charge and selenium has a 2- charge, so it is a straightforward binary compound. Option A and D are incorrect because they suggest the use of roman numerals to represent the oxidation state of calcium, which is not necessary in this case. Option B is also incorrect because it suggests the use of roman numerals and does not follow the naming convention for binary compounds. Option E is incorrect because it suggests the use of the element name instead of the compound name.
