Question

Other than the names of the ions, how does the name of CaS differ from the name of CdS?

Answer 1

Answer:Calcium Sulfide and Cadmium Sulfide

Explanation:

Ca on the periodic table is named Calcium (atomic number 20), and Cd on the periodic table is named Cadmium (atomic number 48).

Answer 2

The symbol of the cations is not derived in the same manner.

Explanation:

• In $'CaS',$ the cation is calcium, and in $'CdS',$ the cation is cadmium.
• It can be seen clearly, that the symbol $'Ca'$ is the first two letters of the name 'calcium' but in cadmium, the symbol is $'Cd',$ the first and the third letter.
• Thus, the derivation of the symbols from their names is not done in the same way.
• This is the second point of difference between them.
