There is only one orbital in the s sublevel. It can hold up to two electrons.
Answer: iron (iii) oxide, Fe2O3.
Explanation: we must calculate the oxidation state of Fe in Fe2O3
Fe2O3 = 0
2Fe + 3(-2) = 0
2Fe — 6 = 0
2Fe = 6
Fe = 6 /2 = 3
So the oxidation state of Fe in Fe2O3 is +3
So the name of the compound is iron (iii) oxide
Your answer would be, The lower the group number, the lower the period numbers, therefore, metalloids are found in a diagonal moving down from left to right.
Hope that helps!!!
