yes, electrons may change energy levels through a gain or loss of energy.
Carbon has four electrons in the outermost energy level, which is energy level two. It needs eight electrons to have this energy level filled.
Magnesium has two electrons in its first energy level, eight electrons in its second energy level, and two electrons in its third energy level, for a total of 12 electrons.
Argon has 2 electrons in the first energy level, 8 electrons in the second energy level, and 8 electrons in the third energy level.
Aluminum has 3 electrons in its outermost energy level.
A neutral sulfur atom has 6 electrons in its outermost energy level. Sulfur has 16 electrons, with 2 electrons in the first energy level, 8 electrons in the second energy level, and 6 electrons in the third and outermost energy level.
In the second energy level of an atom, there can be a maximum of 8 electrons. Magnesium has 12 electrons in total, with 2 electrons in the first energy level and 8 electrons in the second energy level.
As red and blue light energy is absorbed by Chlorophyll electrons in outer shell are excited & raised to a higher energy level.
An argon atom has 2 electrons in its first energy level, 8 electrons in its second energy level, and 8 electrons in its third energy level.
The second energy level can hold a maximum of 8 electrons. Magnesium has 12 electrons, so in its second energy level, there will be 8 electrons (2 in the first energy level and 8 in the second energy level).
There is no third energy level of oxygen, there is only two. The second energy level has 6 electrons.
2 electrons are in magnesiums last energy level
there are 2 electrons in potassium's innermost energy level
