Question

question 9 1 pts orbitals are defined by which term? composition energy level number of electrons spin direction question 10 1 pts what is the number of electrons in an electrically neutral atom equivalent to? atomic weight number of neutrons atomic number mass number

Explanation:

• For Question 9: Orbitals are regions in an atom where electrons are likely to be found and are defined by energy levels. Different energy levels have different types of orbitals (s, p, d, f).
• For Question 10: In a neutral atom, the number of electrons is equal to the number of protons, and the atomic number is defined as the number of protons in an atom.

Answer:

Question 9: energy level
Question 10: atomic number
