it does not form strong bonds, so it breaks apart.

it has 4 valence electrons so it easily bonds to other molecules

it has valence electrons.

It would be the third answer

Explanation:

It is because carbon is so readily to bond with other answers

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
