Answer:
Step-by-step explanation:
Here, we want to select the wrong option about valence electrons
Let us consider the given options one after the other:
a) This is correct. They are the means through which atoms combine to give molecules through chemical bonding
b) This is correct. They reside in the farthest energy level from the nucleus
c) This is correct. With a few valence electrons, such as 1, 2 and 3: the type of bonds formed by the atom would be electrovalent or ionic. While with higher number of valence electrons, the atom is likely to enter into covalent bonding
d) This is incorrect. Valence electrons are not found in the nucleus
