Question

3. What three things can an atom do with its electrons in order to satisfy the octet rule?

4-What is the smallest difference in electronegativity (EN) between atoms that would indicate the formation of an ionic bond?

8. What is the formula for the compound formed with calcium ions and oxide ions?

9. Is sodium chloride, NaCl, a binary compound?

10. Which polyatomic ion is positively charged?

11. In a Lewis structure, which is shown by using a straight line, a bonding pair or a lone pair?

12. In a Lewis structure, which is shown by using a pair of dots, a bonding pair or a lone pair?

19. Do single, double, and triple bonds all count the same in the VSEPR model.

20. What is the bond angle in a water molecule?

21. Why is the bond angle in water less than the normal angle for the tetrahedral shape?

22. What is the prefix for 8 atoms in a binary molecular compound?

23. What is the name of P4S3?

It can share equally its electrons (nonpolar bonding)

It can share inequally its electrons (polar bonding)

It can donate/strip electrons (ionic bonding)

ionic bonding is generally calcualted as a differecnece of EN = 1.4

Ca+2 and O-2 --> CaO(s) Calcium oxide

True, it is binmary since it has 2 different atoms
