How many electrons are in polonium with a -3 charge?

Chemistry

Elina [12.6K]4 years ago
6 0
Polonium has an atomic number of 84 meaning it has 84 protons. Usually, this means there would also be 84 electrons in a normal element. A -3 charge means that there are 3 more negative electrons that positive protons so the overall number of electrons would be 87.

What is the mass of 3.01x1023 atoms of iron(atomic mass of fe=56)
nlexa [21]

Answer:

N = n× l

N = number of entities

n= moles

l = Avogadro's constant = 6.023 × 10^23

3.01 × 10^ 23 = n * 6.023 × 10^23

n = 3.01 × 10^23/6.023 × 10^23

n= 0.5moles

Molar mass = mass/ number of moles

Molar mass = 56

mass = 56 × 0.5

= 28g

Hope this helps.
