A500 gram piece of metal has a volume of 2.75cm3 what is the density

Explanation:

Given that the volume of a piece of metal =

Mass of piece of metal= 500 g

Formula to calculate the density is given by :-

Then, the density of piece of metal is given by :-

 [Rounded to the nearest two decimal places.]

Hence, its density of piece of metal=

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
