This increase in energy is usually described symbolically by saying that one of the outermost electrons "jumps" to a "higher orbit".
An atom's size is dictated by how far away from the nucleus its outermost electrons are.
All elements in the p-block have their outermost electron in a p-subshell.
An onion is like an atom, the outside layer or shell being the negative field of orbit for the outermost electron.
This causes the outermost electron to be attracted to the positive proton in the center.
The outermost electron is not disturbed much by the others, so how it reacts to microwaves can be accurately determined.
It is an interaction between the incident photon and the outermost electron.
In forming compounds, the atom loses its two outermost electrons and one of the 4f-electrons, which belongs to an open subshell.
If a certain period has number , it consists of elements whose outermost electrons fall in the th shell.
This attraction may be seen as the result of different behaviors of the outermost electrons of atoms.
