How many electrons does an Fe atom have in its 3d subshell quizlet? kvargli6h and 14 more users found this answer helpful. 4. Since the last shell of a potassium-ion has eight electrons, the valence electrons of potassium-ion (K +) are eight. They also participate in the formation bonds. You can easily determine the number of valence electrons an atom can have by looking at its Group in the periodic table. The presence of eight electrons in the valence shell of an atom imparts stability to that particular atom. The valenceshell is the shell that follows the electron configuration. The terms oxidation degree and valence may not be the same, but they are numerically almost identical. Explanation: Every element in the boron group has three electrons in its outermost shell (so-called valence electrons), and for each element there is a sharp jump in the amount of energy required to remove the fourth electron, reflecting the fact that this electron must be removed from an inner shell. If you look at the Periodic Table, you will know that Carbon is found in Group 14. Here, the d-orbital is filled with electrons. star. Answer:a) How many valence electrons does element Y have ?Ans.
