question 1 (0.5 points)
give the best systematic name for the compound
bao 1 2
a. boron b. barium c. monobarium d. oxygen e. oxide
f. monoxide g. barium (ii) h. teflon

Explanation:

BaO is an ionic compound. The metal is barium (Ba) and the non - metal is oxygen which forms an oxide ion. In naming ionic compounds, we first name the metal and then the non - metal with the ending 'ide'. Barium has a +2 charge in this compound but for main group metals like barium in simple ionic compounds, we don't usually write the oxidation state in the name (unlike transition metals). So the name is barium oxide.

Answer:

1. B. barium
2. E. oxide
