D. All of the answers are true
Remember, 1 mole= 6.022x10^23 atoms, molecules, or formula units.
Answer is 1.42x10^24
A. This is a FALSE statement because Metals in Group 1 form cations with a +1 charge and not -1.
B. This is a TRUE statement.
C. This is a FALSE statement because metals do not form anions i.e. negatively charged ions but form cations i.e. positively charged ions.
D. This is a FALSE statement because metals do not form anions i.e. negatively charged ions but form cations i.e. positively charged ions.
Answer:
A cation is formed when a metal ion loses a valence electron while an anion is formed when a non-metal gains a valence electron. They both achieve a more stable electronic configuration through this exchange.
When they ask you for the solution they are usually asking for x. So solve for X.
X=-12 so you only have one solution. so the answer is B
