a. combined with neutrons in the nucleus.
b. located in a solid sphere covering the
nucleus.
c. orbiting the nucleus in fixed paths.
d. found in regions called orbitals.

D. found in regions called orbitals

Explanation:

Orbitals are regions in the electrosphere of the atom where the probability of finding the electron, or the wave function that describes the motion of an electron, is greatest.

According to Pauli's Exclusion Principle, each electron has a maximum of two electrons. For orbitals that do not have both electrons, we say they are incomplete and that they are isolated or unpaired electrons.

In addition, when filling orbitals, ie, doing electronic distribution, this should be done according to the Hund Rule or Maximum Multiplicity Rule, which says that this filling should be done in a way that gets as many as possible. of unpaired orbitals.

the element that provides strength to the exoskeletons of clams and oysters is phosphorus.

this is so because calcium carbonate is the main component in the shells. calcium carbonate is strengthened by phosphorus.

explanation:

option a and d is the correct answer

i hope this u

plz mark as the brainliest answer
