12 нояб. 2021 г. · Hydrogen needs one additional electron to achieve a full valence shell, which has a capacity for two electrons. Explanation: Hydrogen requires ... |
Hydrogen atoms need two (2) valence electrons to be stable or "happy." A complete outer electron shell typically consists of 8 valence electrons. |
Videolar Atoms are unstable unless they have 8 valence electrons. Thus, only the noble gasses are “born” to be stable. All other atoms must gain, lose, or share ... |
