What happens when nitrogen fills its valence shell?
When nitrogen fills its valence shell, it achieves a stable electron configuration.
Nitrogen has 7 valence electrons and its valence shell can accommodate a total of 8 electrons. Therefore, in order to fill its valence shell, nitrogen needs to gain 3 more electrons.
In most cases, nitrogen achieves a stable electron configuration by forming covalent bonds with other atoms. It can form three covalent bonds by sharing electrons with other atoms, such as in ammonia (NH3) or nitrogen gas (N2). By forming these bonds, nitrogen can complete its valence shell and achieve a stable electron configuration.
What is one way to describe elements?
One way to describe elements is by their atomic number, which indicates the number of protons in their atomic nucleus. The atomic number determines the element's unique identity and its position on the periodic table.
