Question

multiple answer 15 points. which of the following are properties of metallic bonds? (select all that apply). poor conductors of heat and electricity. large atomic radius. they lose electrons to become cations. they have luster. high ionization energy and electronegativity. they are dull. they are not malleable or ductile. good conductors of heat and electricity. low melting and boiling points. high melting and boiling points. they gain electrons to become anions. they are malleable and ductile. low ionization energy and electronegativity. small atomic radius.

Explanation:

Metals in metallic - bonded substances are good conductors of heat and electricity due to the presence of delocalized electrons. They are malleable and ductile as the layers of metal atoms can slide over one another. Metals have luster because of the interaction of photons with the delocalized electrons. Metals tend to lose electrons to form cations as they have low ionization energy and low electronegativity. Metallic - bonded substances generally have high melting and boiling points due to the strong metallic bonds.

Answer:

They lose electrons to become Cations
They have luster
Good conductors of heat and electricity
High melting and boiling points
They are malleable and ductile
Low ionization energy and electronegativity
