السؤال 111

Which statements explain why neutral isotopes of the same element usually have nearly the same chemical behavior? Select all that apply.

Their electron arrangements are the same.الإجابة الصحيحة
Their different neutrons create different element families.
Ordinary chemical behavior depends mainly on electrons.الإجابة الصحيحة
They must have different proton counts.

الشرح

Neutral isotopes of one element share a proton count and therefore also share an electron count and arrangement, which chiefly governs ordinary chemistry. Different neutron counts change nuclear mass but do not place the atoms in unrelated chemical families.
