25 дек. 2017 г. · The number of valence electrons needed to fill its shell can be determined by inputting the shell level, n, squaring it, and by multiplying by 2.

29 янв. 2024 г. · The number of needed electrons to achieve a full valence shell is calculated by subtracting the current number of valence electrons from eight.

19 февр. 2020 г. · Fluorine only has 9 electrons so 2 for the first shell and 7 on the outter shell. It needs 1 more electron to fill its outter (valence) shell.

20 февр. 2014 г. · This would mean 2 electrons could fit in the first shell, 8 could fit in the second shell, 18 in the third shell, and 32 in the fourth shell.

19 июн. 2023 г. · Since the first noble gas helium has two electrons, we know that only two electrons are needed to fill the first shell.
