Transferring 2. Sharing 1 of 10 When do atoms react by transferring electrons? When metals react with non-metals. 2 of 10 When do atoms react by sharing electrons? If the reacting atoms are all non-metals. 3 of 10 What is an ion? A charged particle which has either gained or lost an electron. 4 of 10 In ionic bonding, which reactant becomes positively charged? The metal. 5 of 10 In ionic bonding, which reactant becomes negatively charged? The non-metal. 6 of 10 How do ions bond? The opposite charges attract each other. 7 of 10 After reacting with fluorine, does lithium become positive or negatively charged? Positive. 8 of 10 After reacting with lithium, does fluorine become positive or negatively charged? Negative. 9 of 10 How does covalent bonding work?
