Electrons in the innermost energy levels, closest to the nucleus, require the most energy to be absorbed in order to be excited to higher energy levels. These electrons have lower energy levels due to their proximity to the nucleus, which causes them to experience a stronger attraction and need more energy to be removed.
The producers (such as plants) at the bottom level of an energy pyramid have the most available energy. As you move up the pyramid to higher trophic levels, energy is lost through metabolic processes and heat, resulting in less energy being available to organisms at higher levels.
Electrons with less energy are most likely located closer to the nucleus of an atom. This is because electrons with lower energy levels have lower energy levels and are more strongly attracted to the positively charged nucleus.
The producer (such as plants) has the most energy in an energy pyramid because they are able to convert sunlight into energy through photosynthesis. This allows them to start the energy flow in the ecosystem by producing their own food, which is then passed on to consumers at higher trophic levels.
The energy levels for the states of matter are different. In solids, particles have the least energy and are closely packed together in a fixed position. In liquids, particles have more energy and are able to move around but are still close together. In gases, particles have the most energy and are far apart and move freely.

Ah, what a lovely question. Elements with 3 energy levels are like a beautiful painting with three layers of colors. You see, elements like lithium and sodium have 3 energy levels where their electrons dance around, creating harmony and balance in the world of chemistry. Just imagine these elements as little artists, each playing their part in creating the masterpiece of life.
The noble gases is the most stable group of elements. They have their outer electron energy levels full, but the number of electrons vary according to which noble gas it is. They are group 18 on the periodic table.
Na, or Sodium, has 3 energy levels. Two electrons in the first level, eight in the second, and one in the third (and outer most) level.
Electrons in the innermost energy levels, closest to the nucleus, require the most energy to be absorbed in order to be excited to higher energy levels. These electrons have lower energy levels due to their proximity to the nucleus, which causes them to experience a stronger attraction and need more energy to be removed.
Electrons in the outer most energy level is called "valence electrons." Groups are the columns of the periodic table. The more valence electrons (up to 8), the closer to the right. The number of electrons needed to make an atom stable is 8. (Minus Hydrogen and Helium, which only need 2 electrons to be stable.)
Generally speaking, it would be 8 electrons, but there are many exceptions.

Group - similar reacting properties. SIMILAR not identicalPeriod - ever increasing proton numberAnswer 2:elements in the same period have the same amount of energy levels (in which electrons orbit around the atomic nucleus)elements in the same group have the same number of valance electrons (which are found in the outer most energy level)
The producers (such as plants) at the bottom level of an energy pyramid have the most available energy. As you move up the pyramid to higher trophic levels, energy is lost through metabolic processes and heat, resulting in less energy being available to organisms at higher levels.
8 are traditionally needed in the valence shell.
