Number of electrons in 1st orbit,2nd orbit,3rd and 4th orbit. |
|
Answer» Answer: 1st 2, 2nd 6,3rd 10 Explanation: Each shell can CONTAIN only a fixed number of electrons: The FIRST shell can hold up to TWO electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold up to 18 (2 + 6 + 10) and so on. The general FORMULA is that the nth shell can in principle hold up to 2(n2) electrons.[1] For an explanation of why electrons exist in these shells SEE electron configuration.[2] Each shell consists of one or more subshells, and each subshell consists of one or more atomic orbitals. |
