Which element has the greatest density at STP?
son4ous [18]

Answer: Option (4) is the correct answer.

Explanation:

It is known that density is mass divided by volume.

Mathematically,       Density = \frac{mass}{volume}

Since, density is directly proportional to mass. So, more is the mass of an element more will be its density.

Mass of magnesium is 24.305 g/mol.

Mass of barium is 137.327 g/mol.

Mass of beryllium is 9.012 g/mol

Mass of radium is  226 g/mol.

Hence, radium has more mass therefore it will have the greatest density at STP.
