The charge on lithium is: +1
Explanation: Lithium belongs to Group I and they lose one electron from their outermost orbital so the oxidation state on lithium metal is +1.

Learning Goal: To learn how to write ionic formulas. Part A Here are some things to remember when dealing with ionic compounds: What is the formula for nickel(III) oxide? Express your answer as a chemical formula. View Available Hint(s) • By convention, the cation is named first and the anion is named second • A Roman numeral in the name indicates the charge of the cation. • The subscripts in the formula represent the number of positive and negative ions...

Write answer such that for example: 1a) formula for #1 1b) total ionic for #1 1c) net ionic for #1 1. sulfuric acid + potassium phosphate 2. sulfuric acid + lithium sulfate 3. sulfuric acid + magnesium nitrate 4. sulfuric acid + sodium carbonate 5. sulfuric acid + sodium hydroxide 6. sulfuric acid + strontium...
Completing and Balancing Neutralization Reactions 10 of 18 For example, if you have a cation with a 1+ charge and an anion with a 2-charge, you will need two cations to balance the charge: I(1+ charge on cation)(2)]+[(2-charge on anion)(1)) = (+2) + (-2) = 0 Complete the following statements regarding the number of cations and anions present in the various ionic compounds. Match the numbers to the appropriate blanks in the sentences below. Make certain each sentence is complete...
