Answer:
hen the number of neutrons is known and the atomic number of an element is known, it becomes easier to determine the approximate mass number by adding the two.

I think you mean ionic bond and not conic bond. The pair of elements that form an ionic bond are barium and chlorine.
Electrolysis can be used to separate a substance into its original components/elements and it was through this process that a number of elements have been discovered and are still produced in today's industry.
Answer:
1 ) H2O 2) Hydrogen and oxygen 3) Compound
Explanation:
1) To write a chemical formula, you write the number of molecules of an element (2 hydrogen atoms + 1 Oxygen atom, or H2O). The letters represent the element's notation on the periodic table, while the number that follows it represents the number of atoms of that particular element within the compound. If there is no number that follows the letter, there is only one.
2) Letter "H" on the periodic table represents hydrogen, while "O" represents oxygen
3) You can tell that this is a compound because it is made of two or more elements found on the periodic table
