WebFeb 14, 2013 · See answer (1) Best Answer. Copy. Noble gases have completely filled orbitals / energy levels. They generally have 8 valence electrons (helium has only 2) and have stable electronic configuration ... WebJun 8, 2024 · Though Helium has 2 valence electrons and not the usual Octet-8 electrons, it is still considered a Noble Gas. This is because Noble Gases all have a stable and complete configuration among all their elements. So, for example, though Helium has 2 electrons, it is one of the most stable elements. Also, it has 2 energy levels.

WebDec 2, 2016 · Explanation: Electron configuration is just the description of how many electrons are in each orbital. Elements are “built up” by the addition of protons and electrons in a regular sequence that we portray as the Periodic Table. The “noble gases” were called that in historical chemistry because of their stability – they do not react ... WebAug 31, 2024 · They are also very nonreactive as they already have a full valence shell with 8 electrons. Therefore, the noble gases have little tendency to lose or gain electrons. Useful Relationships from the Periodic Table. The periodic table of elements is useful in determining the charges on simple monoatomic ions. For main-group elements, those ... WebOct 5, 2024 · A neon light contains a tiny amount of neon gas under low pressure. Electricity provides energy to strip electrons away from neon atoms, ionizing them. Ions are attracted to terminals of the lamp, completing the electric circuit. Light is produced when neon atoms gain enough energy to become excited. When an atom returns to a lower energy state ... the abbreviation psa refers to
