Sagot :
Answer:
Noble gas electron configurations are easier to write because they are shorter than full electron configurations.
To understand the chemistry of an element, it's most important to know about the electrons in the highest energy levels.
The Noble gas shortcut electron configuration is a way of summarizing the information about the electrons of an atom which shows only the electrons most relevant for understanding the chemistry of the element.
Subject classification: this is a chemistry resource. Elements forming covalent compounds achieve noble gas configuration by sharing electrons within the atoms, unlike ionic compounds which achieve the noble gas configuration either by gaining or losing electrons from the outermost electron shell.
