In the shorthand method for showing electron configuration, the noble gas preceding the element is used to indicate the core electrons (inner shell electrons), while the valence electrons are indicated by the remaining electron configuration. For example, the electron configuration of potassium (K) can be written as [Ar] 4s¹, where [Ar] represents the noble gas core configuration (argon's electron configuration).
Electron configuration of uranium is: [Rn]5f36d17s2
[Ne] 3s2 3p5 ----------------
One method used to identify the number and location of electrons in atoms is through spectroscopy techniques such as X-ray crystallography or electron microscopy. These methods provide detailed information about atomic structures and electron configurations by analyzing the interaction of atoms with electromagnetic radiation.
Rather than to give a simple number as answer, I suggest to look up Magnesium on wikipedia, where you will even find a picture with the electron configuration. (And this method can be applied to answer the same question for any other element.)

The noble gas core method for cerium (Ce) involves using the electron configuration of the nearest noble gas, which is xenon (Xe). The electron configuration for xenon is [Xe] 5s^2 4d^10. To find the electron configuration of cerium, we add the remaining electrons for Ce after xenon's electron configuration, which is 6s^2 4f^1 5d^1. Therefore, the electron configuration for cerium using the noble gas core method is [Xe] 6s^2 4f^1 5d^1.

To write a statement in shorthand, use symbols or abbreviations to represent words or phrases. Develop your own shorthand system or use an established shorthand method like Pitman or Gregg. Practice regularly to improve speed and accuracy in writing statements in shorthand.

Mathieu Orfila, a Spanish toxicologist, developed a method for detecting arsenic in the bodies of murder victims in the early 19th century. His work played a significant role in the field of forensic toxicology and helped identify cases of arsenic poisoning.
The most common method of poisoning is arsenic, because it is water soluble and tasteless.
Scientific notation.
A shorthand writer is someone who specializes in recording spoken language in shorthand form, which is a method of rapid writing using symbols and abbreviations to capture information quickly. Shorthand writers are commonly used in courtrooms, during interviews, meetings, or other situations where accurate and fast transcription is needed.
