Well, honey, the highest occupied energy level of an atom is called the valence shell. It's where all the action happens, with those sassy electrons strutting their stuff. Just remember, the higher the energy level, the further those electrons are from the nucleus. Keep on shining bright like a diamond, just like those valence electrons!
7 electrons
The period tells you how many energy levels an atom has.
The energy level of an atom is occupied by electrons, which are negatively charged particles that orbit around the nucleus. The energy of these electrons depends on their distance from the nucleus and the specific quantum energy levels they occupy.
It has 2 unpaired electrons and 8 empty electron levels.
You shouldn't use terms like "outer level", because they're confusing. It could potentially mean at least two things, specified more precisely below. The highest occupied energy level of a ground state neutral carbon atom, the 2p level, has two electrons. The number of electrons in a ground state neutral carbon atom that have a principal quantum number of 2 (the highest associated with any electrons in such an atom) is four.
The 3rd energy level is the highest occupied energy level for chlorine with seven electrons.
A neutral chlorine atom has 17 electrons. In its ground state, the highest occupied energy level for chlorine is the third energy level (n=3), which can hold a maximum of 8 electrons. Therefore, the highest occupied energy level for a neutral chlorine atom contains 7 electrons.
the period number tells which is the highest energy level occupied by the electrons
the period number tells which is the highest energy level occupied by the electrons
There are 2 electrons in the highest occupied energy level of a neutral strontium atom, as the electron configuration of strontium is [Kr]5s^2.
7 electrons would be in the highest occupied energy level of a 7A element. Group 7A elements have 7 valence electrons, which occupy the highest energy level of the atom.

Sodium: Na(2, 8, 1 ) so there is one electron in the highest (3rd) level
2. the number of electrons on the outermost level is always equal to the group number. Barium is group 2 therefore it's outermost energy level contains 2 electrons
