6. valence, 7. full outer shell, 8.8, 9.lose/gain, 10. share, 11. ionic, 12. covalent, 13. ions, 14, negative

Explanation:

6)Valence

7)stability

8)2

9)transfer of

10)share

11)covalent

12)ionic

13)ion

14)negative

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )

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
