Question

Where are the electrons inside an atom?
A.The electrons are in the nucleus of an atom
B.They are arranged in energy levels
C.The electrons are spread equally throughout the atom

Answer 1

Answer: B.They are arranged in energy levels

Explanation: Electrons orbit around the nucleus of an atom, and are not spread around equally throughout an atom because there are a different amount of electrons that can fit in each energy level or electron shell (both are the same thing). For example the first energy level can hold up to 2 electrons, the second shell can hold up to 8 electrons, the third can hold up to 18, and so on represented by the equation 2(n^2)
