Use the periodic table(https://ptable. com/?lang=en#Properties) to identify an element that has similar chemical properties as those of the element krypton (K). Explain your reasoning.

"the periodic table is arranged in order of atomic number."

i think   the answer is c hope i'm right

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

i wish i could but this one is weird give me abc and i can solve it.
