Question

use the periodic table to select which type of bond is present and which of the listed properties is most likely for each substance.
a =
b =
substance\ttype of bond\tlikely property
cu3zn2\ta\tb
o2\tc\td
brittle
low melting point
conducts electricity as a solid

Explanation:

Step1: Analyze $Cu_3Zn_2$

$Cu_3Zn_2$ is an inter - metallic compound. Inter - metallic compounds have metallic bonds. Metallic substances can conduct electricity as solids due to the presence of delocalized electrons.

Step2: Analyze $O_2$

$O_2$ is a non - metal molecule. The bond between oxygen atoms is a covalent bond. Non - metal covalent substances like $O_2$ usually have low melting points as they are held together by weak intermolecular forces.

Answer:

$Cu_3Zn_2$: A. metallic bond, B. conducts electricity as a solid
$O_2$: C. covalent bond, D. low melting point
