is a level of bad energy that is confined spatially can only take on certain discrete values of energy.
Mercury has 80 electrons distributed in 6 energy levels,; namely:First Energy Level: 2Second Energy Level: 8Third Energy Level: 18Fourth Energy Level: 32Fifth Energy Level: 18Sixth Energy Level: 2Accordingly, Mercury has on the outer shell 2 electrons to share with in any chemical reaction by an ionic bond.
Energy Levels. 1st energy level can contain 2 Electrons 2nd energy level can contain 8 Electrons 3rd energy level can contain 18 Electrons 4th energy level can contain 36 Electrons
4. 1st shell: s subshell 2nd shell: s and p subshells 3rd shell: s, p and d subshells 4th shell: s, p, d and f subshells
There are three electrons in boron's outer energy level.
This electron shell is near the atomic nucleus.
The sub-level s of energy that make the o shell is the K-shell.
Actually each energy level is considered to be a shell and the electrons are moving in the shell (in fixed paths).
Shell or energy level corresponds to the shell in which the electrons are present.
The outermost energy level of an atom is referred to as the valence shell.
Each electron shell corresponds to a different principle energy level. Each shell can contain only a fixed number of electrons.
The question is somewhat vague. If the question were written as an atom contains seven electrons in the outermost energy level and that outermost shell is a p-shell then the atom is a halogen. If the atom contains seven electrons in the outermost energy level and that outermost shell is a d-shell or f-shell then the atom is a metal.
the energy levels are as follows: first shell 2 second shell 8 third shell 5
is a level of bad energy that is confined spatially can only take on certain discrete values of energy.
The K shell's 1s orbital is te first energy level of an electron.
These are the valence electrons.
