Question

electrons farther away from the nucleus in an atom have _______ compared to those closer to the nucleus.
a) lower energy
b) the same energy
c) higher or lower energy, depending on the element
d) higher energy
question 15 (5 points)
listen
the distance between consecutive peaks or troughs in a wave is
a) frequency.
b) wavelength.
c) amplitude.

Explanation:

For the first question:

• Electrons in an atom follow energy - level principles. Electrons farther from the nucleus are in higher - energy orbitals. This is because of the electrostatic force and the concept of energy levels in atomic structure.

For the second question:

• By definition, the wavelength of a wave is the distance between consecutive peaks (crests) or consecutive troughs. Frequency is the number of waves passing a point per unit time (\(f=\frac{1}{T}\), where \(T\) is the period), and amplitude is the maximum displacement from the equilibrium position of the wave.

Answer:

For the first question: D. higher energy
For the second question: B. wavelength
