Answer:
Ca.
Sb.
Explanation:
a. When comparing the two elements Ca and As , the more metallic element is:__________ based on periodic trends alone.
The correct option is Ca. Ca belongs to group 2 which is more easily give off it's electrons, compared to As which is a group 5 member.
c. When comparing the two elements Sb and Pb , the more metallic element is:___________ based on periodic trends alone.
The correct option here is Pb. Thhs is because ionization energy decreases down the group. Pb has a lower ionization enthalpy than Sb
Answer:
a. 4, b. 6, c. 4, d. 2
Explanation:
The coordination number (CN) of a complex of a compound is the number of bonds that a metallic ion does with the binders, which can be equal or not.
a. The metallic ion is the iron (Fe), and it's bonded to 2 gly and 2 H2O, thus, CN = 4.
b. EDTA is a hexadentate molecule, thus, it forms 6 bonds with the metal Cr, and CN = 6.
c. The metal is Pt, which has 4 bonds with NH3, thus CN = 4.
d. The metal is Ag, which forms 2 bonds with NH3. NO3 is bonded with the structure and not with the metal. Thus, CN = 2.
