WebEach electron shell is given a number 1, 2, 3, and so on, starting from the one closest to the nucleus (the innermost shell). Each shell can hold up to a certain maximum number of electrons. The distribution of electrons in the various shells is called electronic arrangement (or electronic form or shape).

Web: Group electrons in pairs to keep track of how many you have drawn. This will also help you draw dot and cross diagrams later. 7. Draw another circle around the second electron shell. This is the third shell. 8. Add up to eight electrons to the third shell. 9. Draw the last circle around the third shell. This is the fourth electron shell. 10. WebAug 15, 2024 · When hydrogen shares electrons with oxygen, the outermost shell of the hydrogen atoms are full with 2 electrons and oxygen’s valence shell is full with 8 electrons.. Hydrogen and oxygen are nonmetals that bond through covalent bonds, that is, they share pairs of electrons to obey the octet's rule.The octet´s rule states that atoms will gain, lose …
WebDec 3, 2024 · The third shell can accommodate as many as 18 electrons. In general, the maximum number of electrons that can be present in any shell is 2n2 where n is the number of energy shell. Thus, the first orbit (n = 1, known as K shell) can contain 2 × 12 = 2 electrons, the second orbit (n = 2, known as L shell) can contain 2 × 22 = 8 electrons.
