What are chemical symbols? How were they represented earlier? What are the features of the modern system?
Answers
Answer:
A chemical symbol is a notation of one or two letters representing a chemical element. The exceptions to the one- to two-letter symbol are the temporary element symbols assigned to designate new or to-be-synthesized elements. Temporary element symbols are three letters that are based on the element's atomic number.
The last year has brought about unexpected changes for all kinds of organisations, and organisational plans around digital transformations are no exception. However, instead of slowing down or pausing those transformations during a financially tough year, many organisations have sped them up. Amid the pandemic, in a July 2020 IDG survey, 41% of IT decision-makers said their technology budgets would increase in the next 12 months; another 35% said they would hold steady.
If your business is undergoing or planning to undergo digital transformation, you may need to take a deeper look at which of the many solutions meet your needs. However, the myriad options and progressive evolutions can overwhelm even the most experienced C-suite leaders, especially in this ever-evolving space.

Answer:
Hi,
A chemical symbol is a shortened method of representing an element .
Most chemical elements are represented symbolically by two letters, generally the first two in their name. In some cases, the first letter together with some other letter from their name was used, particularly when their first two letters had already been allocated to another element.
The modern system of representation was given by Jon's jacol berzilious that the symbols should be made of the first or first two letters of the names of the elements .
