Which of the following is true about electron energy shells?
A
They represent regions around the nucleus in which the electrons orbit.
B
The shells closest to the nucleus contain electrons with higher energy.
C
They contain electrons of the same energy.
D
a and b only.
E
a and c only.
Verified step by step guidance1
Understand that electron energy shells, also known as electron orbitals, are regions around an atom's nucleus where electrons are likely to be found.
Recall that electrons in shells closer to the nucleus generally have lower energy compared to those in shells further away. This is because electrons in outer shells have more potential energy due to their position.
Recognize that within a given shell, electrons can have the same energy level, which is why they are grouped together in that shell.
Evaluate the given statements: (a) is true because it describes the general concept of electron orbitals. (b) is false because electrons closer to the nucleus have lower energy, not higher. (c) is true because electrons in the same shell have similar energy levels.
Based on the evaluation, the correct answer is 'a and c only' because both statements accurately describe properties of electron energy shells.
