What properties of metals are explained by its mobile electrons? strength, malleability, ductility, heat conduction, current conduction, luster, opacity

Due to the presence of mobile or moving electrons in an atom they are good conductor of heat and electricity. Thus, the heat conduction and current conduction properties of metals are explained by its mobile electrons.

The other mentioned properties of metal are strength which can be explained by type of bonding within the metals, malleability explains the tendency of metals to be flattened into thin sheets, ductility explains the tendency to be stretched into wires, luster means the surface of metal is shiny and opacity is measure of impermeability that is to what extent they can pass light through them, metals are opaque, can not pass light through them or they are not transparent . All these properties are not because of mobile electrons in metals.

Therefore, correct properties are heat conduction and current conduction.

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons
