Study Notes
Ionic Bonds Overview
- Ionic compounds are formed through the transfer of electrons between metal and nonmetal atoms.
- Metal atoms typically lose electrons while nonmetal atoms gain electrons to achieve stable electronic configurations.
Selenium Ion Formation
- When a selenium atom seeks a stable set of valence electrons, it typically forms a Se2− ion.
- The correct answer for the ion formed by selenium is D: Se2−.
Electron Transfer in Ionic Bonds
- The fundamental nature of ionic bonding involves a metal atom losing electrons, while a nonmetal atom gains those electrons.
- Therefore, the best description of electron transfer in ionic bonds is A: A metal atom loses electrons and a nonmetal atom gains electrons.
Constructing Ionic Bonds
- When creating an ionic bond between beryllium and chlorine, the next step involves adding another chlorine atom to balance the bond.
- The correct action is D: Add another chlorine atom.
Zinc and Phosphorus Interaction
- In the compound zinc phosphide (Zn3P2), phosphorus has five valence electrons.
- Each zinc atom loses two valence electrons to maintain charge neutrality in this compound.
- The correct answer regarding how many valence electrons each zinc atom loses is B: 2.
Rubidium Nitride Formula
- Lithium nitride has the formula Li3N and serves as a reference for similar compounds.
- Rubidium, which belongs to the same chemical family as lithium, will have a similar ionic compound structure.
- The formula for rubidium nitride is Rb3N. The correct answer is C: Rb3N.
