Answer:
The number of atoms in the outermost shell
Explanation:
For example, the electron shells in the alkali metals contain the following numbers of electrons:
Li: 2, 1
Na: 2, 8, 1
K: 2, 8, 8, 1
They all have one electron in their outermost shell, and they have similar chemical properties.
Answer:

Explanation:
SO in order to calculate the specific latent heat of fusion, you need to remember the formula:

Where
representes the specific latent heart of fusion.
represents the heat energy added, usually represented in kJ
represents the mass of the object, in kg.
Now that we have our formula we just have to put our values into the formula:



SO our answer would be 
n = m/M = 2/18 = 1/9 ~0,1 mol
