The isotope notation :
Given
53 protons and 20 neutron
Required
The isotope notation
Solution
Isotopes are elements that have the same atomic number with a different mass number
The following element notation,
X = symbol of element
A = mass number
= number of protons + number of neutrons
Z = atomic number
= number of protons = number of electrons, on neutral elements
So the mass number of element = 5 + 6 11
Atomic number = 5
The symbol :
0.9645 cm³ is the occupied volume by a 21.8 g sample of osmium of density of 22.6 g/cm^3.
Given values are:
- Mass, m = 21.8 g
- Density, d = 22.6 g
Density is given by,
