To determine the formula for lithium sulfide using the crisscross method, you would write the symbols for lithium (Li) and sulfide (S) with their charges. The lithium ion has a charge of +1, while the sulfide ion has a charge of -2. By crisscrossing the charges, you get Li2S as the formula for lithium sulfide.

What are the ions and crisscross method for lithium sulfide?
Lithium forms Li+ ions, and sulfur forms S2- ions. To determine the chemical formula for lithium sulfide using the crisscross method, you would cross the charges of the ions to get Li2S.
What is the negative ion of lithium sulfide?
The negative ion of lithium sulfide is sulfide ion (S2-). This is formed when lithium sulfide (Li2S) dissociates into its ions in solution.
What is the positive ion for lithium sulfide?
The positive ion for lithium sulfide is Li+ (lithium ion).
What is the complete ionic equation of the reaction between hydroiodic acid and aquous lithium sulfide?
An ionic equation refers to a chemical equation wherein electrolytes are written as dissociated ions. The complete ionic equation of the reaction between hydroiodic acid and aqueous lithium sulfide is: 2HI + Li2S -> 2LiI + H2S.
How are these ions distinguished from one another in writing formulas for compounds?
Ions are distinguished by their charge and ratio in chemical formulas. The charge of each ion determines how they combine to form a neutral compound through the crisscross method. The crisscross method helps ensure that the total positive charge equals the total negative charge in the compound.

What is the correct formula for an ionic compound that contains aluminium ions and sulfide ions?
The correct formula for an ionic compound containing aluminum ions and sulfide ions is Al2S3. This formula results from the balance of charges between the 3+ charge of aluminum ions and the 2- charge of sulfide ions to form a neutral compound.
Why are there more sodium ions in the sulfide compound?
In a sulfide compound, sodium ions are present to balance the charge of the sulfide ions. Sulfide ions (S²⁻) carry a -2 charge, meaning two sodium ions (Na⁺), each with a +1 charge, are needed to achieve charge neutrality. Thus, for every sulfide ion, there are typically two sodium ions in the compound, resulting in a higher number of sodium ions relative to sulfide ions.
What does the formula of sodium sulfide mean?
The formula of sodium sulfide, Na2S, indicates that each sodium sulfide molecule contains two sodium (Na) ions and one sulfide (S) ion. The ratio of sodium ions to sulfide ions in sodium sulfide is 2:1.
What type of compound is Li2S?
Li2S is a polar covalent compound because the electronegitvity of Li is 1.00 and of S is 2.5. Thus the difference is 1.5 and that makes it polar covalent.
What is the scientific name for Na2S?
It is a bond between Sodium ions and Sulfide ions. Sodium Sulfide.
