What is the formula unit for a compound made from li and cl? (5 points)
lici because the total negative charge on cl is one.

licl because the total negative charge on li is two.

li cl because the total positive charge on al is one.

licl because the total positive charge on li is two.

LiCl because the total negative charge on Cl is one.

Explanation:

By criss crossing the charge numbers, we find the chemical formula of a compound

For example Aluminium chloride

Al has 3+ charge and Cl has 1- charge  

3 becomes the subscript of Cl and 1 becomes the subscript of Al  

So the chemical formula will be

Few examples are as follows:

Sodium Hydroxide is NaOH as Na the charge is and OH the charge is

Sodium phosphate is as sodium has charge and phosphate has charge.

Sodium sulfate is as sodium has charge and sulfate is charge.

Sodium chloride will be NaCl as sodium has charge and chloride has charge.

Calcium phosphate will be because Calcium possess charge and phosphate has charge.

Li has a charge of and Cl has a charge of and hence  the chemical formula we get is
