The modern model of the atom shows that electrons are(1) orbiting the nucleus in fixed paths(2) found in regions called orbitals(3) combined with neutrons in the nucleus(4) located in a solid sphere covering the nucleus



Answer :

The correct answer is 2. Electrons are found in regions called orbitals. These orbitals are neither fixed paths nor solids, but are better visualized as cloud-like space, making 1 and 4 incorrect. Additionally, 3 is incorrect because the orbitals are outside of the nucleus, while the protons and neutrons are inside the nucleus. Hope I helped! :) Cheers!
