34. What is a double bond?
Two pairs of electrons shared between four atoms NB Pg. 25
36. Magnesium Bromide is an ionic compound with the chemical formula MgBr2. What does the “2” tell you?
There are two bromide ions for every magnesium ions NB Pg. 26
42. When electrons are TRANSFERRED between two atoms, a covalent bond is formed
False, shared NB Pg. 26
43. When an atom gains an electron it becomes a POSITIVE ion
False negative NB Pg. 26
44. The attraction between a positive ion and a negative ion results in a COVALENT bond
False, ionic NB Pg. 26
48. Chemical bonds form when valence electrons (blank) between atoms
Transferred/shared NB Pg. 28
52. Name this compound Fe(CO3)2
Ionic; Iron (IV) carbonate Periodic table
66. Give the chemical formula of Beryllium acetate?
Be(C2H3D2)2 NB Pg. 30
68. What type of bond is formed between two oxygen atoms? What will happen to form the bond?
Covalent; 2 oxygen atoms form a double bond by sharing 4e- between them. Pg. 29/Periodic table
70. What type of bond is formed between Sodium and Chlorine? What will happen to form the bond?
Ionic; Na gives it 1 valence e- to Cl - - Na +1; Cl accepts 1 valence e- to go w/ the 7 it already has - - Cl -1. Pg. 29/ periodic table
