When writing the chemical formula for an ionic compound, what is the correct practice regarding subscripts of '1'?

• Always write the subscript '1' for clarity.

• Only write '1' if it's the first element in the formula.

• Never write the subscript '1'; it is implied.

• Write '1' only if the element has a charge of +1 or -1.

What is the correct way to represent charges in the final chemical formula of an ionic compound?

• All charges should be explicitly written as superscripts.

• Only positive charges should be written as superscripts.

• Only negative charges should be written as superscripts.

• No charges should be explicitly written in the final formula.
