What are the characteristic property's of metals such as malleability and high conductivity are due to ?
1 answer:
Answer:
Metallic Bonding
Explanation:
Conductivity occurs when electrons or ions are free moving. The conductivity in metals is due to electrons being delocalized in a sea of electrons. Metals contain metallic bonding which allows the electrons to freely move.
Malleability happens when adjacent layers of positive ions move relative to one another while being in contact with the sea of electrons from the metallic bonding.

(4) zinc
Explanation:
Given parameters:
Mass of the sample = 10g
Condition = STP
Unknown:
Element with the least volume = ?
Solution:
The number of moles of substance as STP can be derived using the equation below;
Volume of substance = number of moles x 22.4
Number of moles =
since mass = 10g
Number of moles of Al = = 0.37mole
Number of moles of Ti = = 0.29mole
number of moles of Mg = = 0.47mole
Number of moles of Zn = = 0.15mole
Zinc has the least number moles and it will have the lowest volume at STP because the volume directly proportional to number of moles.
