Question

Three differences between dalton's and berzelius' method of allocating symbols to the elements.

Answer 1

A symbol is defined as an short hand sign or abbreviation for the representation of an elements.
Dalton Approach to assign Symbols:
---> Dalton used shape of Circle for assigning symbol for element.
О --- oxygen
Ο with dot inside -- Hydrogen
Ο with dark shade -- carbon
Ο with N alphabet - Nitrogen
Ο with I alphabet -- Iron
⊕-- Suphur

J.J Berzelius suggested that symbols of the elements can be written by English names.
1. For most of the elements , the first alphabet in the name of element is written in capital form and is taken as symbol for that element.
For eg: Oxygen –O
Sulphur --S
Carbon -- C
2. For some elements, the first letter written in capital form and next prominent letter written in smaller form the name of element is taken as its symbol.
Eg: Nickel : Ni
Neon--Ne
Calcium- Ca
Silicon- Si
Chromium-Cr
3. later Some elements were named on Latin name
For example:
Potassium - Latin Name - Kalium- K
Sodium- Latin Name- Natrium- Na
Gold- Aurum-Au
Silver-- Argentum- Ag
4. Some elements were represented based on country name, planet name or scientist names
For example:
Element- Bhorium- Scientist name - Bohr- Symbol- Bh
Element - Mendelevium- Scientist name- Mendeleev - Symbol- Md
Element - Indium--Country name- India- symbol- In
Element - francium- Country name- France- Fr
Element - Plutonium-Planet name- Pluto
