    on “One way in which elements differ from each other is the structure of the electron cloud in each element’s”

    Electrons that are further away from the nucleus have more energy. As they enter an "excited" state, they jump up orbits.

    In an electron cloud, an electron that is farther away from the nucleus has a higher energy than an electron near the nucleus. Since these electrons are from the nucleus, then they are not stable and contains a lot of energy as they are moving very fast in order to achieve stability.

    obviously it will have lower energy

    an electron that is farther away from the nucleus has a greater charge than an electron near the nucleus.

    Reply Explanation:

    Electron that is farther away from the nucleus have high level of energy because they are in excited state. When the electrons are farther from nucleus then there is decreased interaction between the nucleus and electrons, and thus these electrons can be removed by spending less amount  of energy. Hence we say that they are in excited state.

    Reply More energy Explanation:

    An stable atom consists of electrons and the nucleus which are balanced in the number of electrons and protons. In a stable atom the electrons do not fall into the nucleus. The electrons stay in their orbitals according to the energy levels of the electrons. The electrons near the nucleus have less energy while the electrons farther from the nucleus have more energy.

    Answer is: (C) a higher energy than an electron near the nucleus.

    Electrons can jump from one energy level to another, absorbing or emitting electromagnetic radiation with a frequency ν (energy difference of the levels).

    When electron jump from higher to lower energy level (shell), it emitting (releasing) energy.

    When the electron changes from n=4 (fourth shell) to n=2 (second shell), the photons are emitted.

    The electron cloud is split up in 3 areas.

    1) Inner Electron Cloud

    2) Outer Electron Cloud

    3) Valence Electrons

    Your inner cloud is the electrons CLOSEST to the nucleus.

    Your outer cloud is the electrons in the MIDDLE of the Inner and Valence.

    Your valence electrons are the OUTER LAYER of electrons. These electrons are important to bonding, and also are what decide where on the periodic table of elements. For example:

    197 Au 79

    This element is GOLD. It has 1 valence, therefor it is where it is in the period. Ionization could change this number however.
