Which statement best describes the properties of metals? they are shiny and bend without breaking. they are dull and are good electrical insulators. they conduct electricity well and are brittle. they can be flattened and do not conduct heat well.

They are shiny and bend without breaking.

Explanation:

Properties of metal:

From the given statement which matches with properties of metals enlisted above is:'They are shiny and bend without breaking.'

number of molecules / avogadro's number * molecule molecular = mass

explanation:

we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –  

6.022

x

10

23

. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,  

u

f

6

will have a gram-molecular weight of 352g.

b
