How many energy levels does MG have?
That means there are 12 electrons in a magnesium atom.
Looking at the picture, you can see there are two electrons in shell one, eight in shell two, and two more in shell three.

Are there 7 energy levels?
Thus, the first level can contain up to 2 electrons, 2(12) = 2; the second up to 8 electrons, 2(22) = 8; the third up to 18, 2(32) = 18; and so on. Only seven energy levels are needed to contain all the electrons in an atom of any of those elements now known.
Is the second energy level of the oxygen atom full?
The second level can hold up to eight electrons. A partially-filled energy level is not as stable as a full or an empty energy level. Atoms become more stable by losing electrons or attracting electrons from other atoms. … The outer energy level of oxygen is the second level, so it can hold up to eight electrons.
Which energy level has the most energy?
What Are Energy Levels?Energy levels (also called electron shells) are fixed distances from the nucleus of an atom where electrons may be found. … Q: In the atomic model Figure above, where would you find electrons that have the most energy?A: Electrons with the most energy would be found in energy level IV.More items…•
Why do valence electrons have the most energy?
The outer energy levels have higher energy than the the inner energy levels or shells . The electrons want to be closer to the nucleus because opposite charges attract each other . … Farther the satellite less is the velocity and same is the case with the electron ..
Is oxygen stable before bonding?
Atoms like oxygen (O) will form two covalent bonds because they already have six valence electrons and only need two more electrons obtained by sharing. … However, the one-proton nucleus is very weak and has trouble keeping the shared electrons around the hydrogen atom for very long.
How do you find the highest occupied energy level?
The highest occupied energy level in an atom is the electron-containing main energy level with the highest number.
How many energy levels are there?
Every atom has an infinite number of energy levels available, depending on how much energy has been absorbed. In the ground state, there are seven (known/most-often-seen) energy levels which may contain electrons. The period number is the same as the highest energy level in that period at ground state.
What are the 4 energy levels?
There are four types of orbitals that you should be familiar with s, p, d and f (sharp, principle, diffuse and fundamental). Within each shell of an atom there are some combinations of orbitals.
Why is 3rd shell 8 or 18?
The third shell of an atom has 18 electrons only not 8 electrons. You might be confused because first the electrons of 4s are filled and then the 10 electrons of 3d shells are filled. They are filled because of the n-l rule. … So after filling the 3s and 3p subshell with 8 electrons, the next shell to fill is the 4s one.
Which energy level has the least energy?
At the lowest energy level, the one closest to the atomic center, there is a single 1s orbital that can hold 2 electrons.
Can a single oxygen atom exist?
The oxygen that we breathe is called O2—that is, it is comprised of two atoms of oxygen. O3 is ozone, such as occurs in Earth’s upper atmosphere, and O (one atom), is atomic oxygen. Atomic oxygen doesn’t exist naturally for very long on the surface of Earth, as it is very reactive.
