Question

what is the name for sf6? sulfur fluoride hexasulfur monofluoride sulfur hexafluoride hexasulfur hexafluoride what is the formula for barium chloride? bcl bacl bacl2 ba2cl positively charged ions are called* cations anions

Explanation:

1. For $SF_6$, in binary covalent - compound naming, the first element is sulfur and the second is fluorine. The prefix 'hexa -' indicates 6, so it is sulfur hexafluoride.
2. Barium has a + 2 charge ($Ba^{2+}$) and chlorine has a - 1 charge ($Cl^-$). To balance the charges, two chlorine atoms are needed for one barium atom, so the formula is $BaCl_2$.
3. Positively charged ions are called cations, while negatively charged ions are anions.

Answer:

1. C. Sulfur Hexafluoride
2. C. $BaCl_2$
3. A. Cations
