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
The highest occupied energy level in Beryllium is the 2s orbital. Beryllium has 4 electrons, with 2 electrons in the 1s orbital and 2 electrons in the 2s orbital.
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.
In a barium atom, there are 2 electrons in the first energy level, 8 electrons in the second energy level, 18 electrons in the third energy level, 18 electrons in the fourth energy level, 8 electrons in the fifth energy level, and 2 electrons in the sixth energy level.
Sodium: Na(2, 8, 1 ) so there is one electron in the highest (3rd) level
The electronic configuration of chlorine is 2,8,7 So there are 7 electrons in the valence shell (or highest energy level).
Sr has two electrons in the highest occupied energy level
Phosphorus has 5 electrons in its highest occupied energy level.
Xenon has a total of 54 electrons. The highest occupied energy level of xenon is the 5th energy level, which can hold a maximum of 18 electrons. Therefore, on the highest occupied energy level of xenon, there are 18 electrons.
Aluminum has 3 electrons in its highest occupied energy level.
The 3rd energy level is the highest occupied energy level for chlorine with seven electrons.
4 energy levels with 2, 8, 8, 2 electrons in the energy levels.
Helium is the noble gas that does not have eight electrons in its highest occupied energy level. It only has two electrons in its outermost energy level.
There are 3 valence electrons in the highest energy level of Nitrogen. Nitrogen has a total of 5 valence electrons.
The highest occupied energy level in Beryllium is the 2s orbital. Beryllium has 4 electrons, with 2 electrons in the 1s orbital and 2 electrons in the 2s orbital.
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
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.
