A) Metals lose electrons to form stable ions that are isoelectronic with the previous noble gas. Explain what is the charge on lithium ion?
B) Type the elemental symbol for another element a metal that would be predicted to have the same charge as the lithium ion.
C) While forming monatomic ions, halogens gain electrons to become isoelectronic with the next noble gas. Explain what is the charge on the iodide ion?
D) Define which is the correct formula for nickel (II) nitrate?
