Question

1. Find the elements sodium, oxygen, and phosphorus on the periodic table. Describe the monoatomic ions each would form. Then, given what you know about chemical bonding, describe and give the formulas for the types of ionic compounds they would produce with each other. Use the periodic table in the Chemistry: Problems and Solutions book to help with your answers.2. Given the chemical formulas of the following compounds, name each compound and state the rules you used to determine each name.KIFe2O3(NH4)3PO4

Answer 1

Answer for 2:

- KI: potassium iodide

- Fe2O3: diiron trioxide

- (NH4)3PO4: ammonium phosphate

Explanation for 2:

• KI,:

The compound KI is called potassium iodide, because it is a hydracid salt that has potassium in the positive parte (that's why it keeps the name of the metal). While the negative parte of the salt comes from the non-metal iodine.

• Fe2O3,:

The compound Fe2O3 is called

, because the molecule of this oxide has 3 oxygen atoms and 2 iron atoms.

• (NH4)3PO4:

The (NH4)3PO4 is a salt called ammonium phosphate, because it is formed from phosphoric acid (that gives the negative part of the salt), and ammonia (that gives the positive part of the salt). The negative part of salt ends in "...ate" because it comes from the acid that ends with the suffix "...ic".
