how many valence electrons does Na have when forming an ionic bond with Cl?
An ionic compound forms when calcium (Z = 20) reacts with iodine (Z = 53). If a sample of the compound contains 9.49 × 1023 calcium ions, how many iodide ions does it contain? (Enter your answer in scientific notation.)
7. What is the formula of the ionic compound that forms when calcium hydroxide reacts with nitrous acid?
How many valence electrons does an atom of praseodymium, Pr, have? How many unpaired electrons does an atom of Samarium, Sm, have? What is the geometry for the ClO4- ion? What is the bond angle in the ClO4- ion?
How many electrons does potassium need to lose to become an ion? Will it become a positively charged cation or a negatively charged anion? How many electrons must nitrogen gain to become like its closest noble gas, Neon? What are valence electrons?
Procedure A. For each compound below: 1. Determine how many valence electrons belong in the Lewis structure for the compound. 2. Draw a Lewis structure in the spaces provided below. Be sure to show the correct number of bonds between atoms and place the correct number of lone pairs on each atom. Remember, hydrogen doesn't get any lone pairs, and all the other atoms like to get an octet. When you are finished, have your instructor check your structures before...
8. How many valence electrons are needed to form a double bond? 9. Why calcium oxide is Cao, not CaO2? (any compound, ionic or molecular compound, the total charge is zero. Ca loses 2 valence electrons to become Ca+2 while o gains two valence electrons to become 02, the total charge is zero. CaO2, is not zero charge, it is -2 net charge.
