What is the atomic sublevel with the next highest energy after 4p?
5s
How many electrons occupy the highest energy sublevel of alkali metals?
90
Only one electron in the highest-energy s sublevel in the ground state are called?
Alkali metals
What indicates the s sublevel in the third main energy level?
The s sublevel in the third main energy level is indicated by 3s.
What is the highest sublevel electrons occupy in uranium 238?
It is the f sublevel. Uranium has the configuration [Rn] 5f3 6d1 7s2.

Why are the valence electrons of calcium in the 4s orbital not the 3d orbital?
The 3d sublevel is not filled until after the 4s sublevel, because the 3d sublevel has more energy than the 4s sublevel, and less energy than the 4p sublevel.
Why does an electron occupy the 4s orbital before the 3d orbit?
The 3d sublevel is not filled until after the 4s sublevel, because the 3d sublevel has more energy than the 4s sublevel, and less energy than the 4p sublevel.
What is the highest sublevel electrons in the element Promethium an f block element occupy?
The highest sublevel that Promethium can have is 4f. It is possible for 14 electrons to be placed around Promethium, since the elements in this sublevel each have 7 orbitals.
How would you justify the presence of 18 elements in the fifth of period of periodic table?
In the fifth period of the periodic table, the atoms of the elements in the first two groups are adding 1 and 2 electrons, respectively, to their highest energy 5s sublevel. Starting in group 3/IIIB and going through group 12/IIB, the atoms of those elements are adding electrons to their highest energy 4d sublevel. Since the d sublevel can contain a maxium of 10 electrons, there are 10 elements whose atoms are filling the 4d sublevel. Once the 4d sublevel is filled, the next higher energy sublevel is the 5p sublevel. Starting with the group 13/IIIA elements, the 5p sublevel is being filled. Since a p sublevel can contain a maximum of 6 electrons, there are six elements whose atoms are filling the 5p sublevel. 5s sublevel filling: 2 elements 4d sublevel filling: 10 elements 5p sublevel filling: 6 elements --------------------------------------- Total: 18 elements For a printable periodic table that includes electron configurations, go to the following link: http://www.nist.gov/pml/data/periodic.cfm
Why do you believe that the valence electrons of calcium and potassium reside in the 4s orbital rather than in the 3d orbital?
The 3d sublevel is not filled until after the 4s sublevel, because the 3d sublevel has more energy than the 4s sublevel, and less energy than the 4p sublevel.
What is the highest sublevel in actinium?
Actinium is in period 7, group 3A : so 7s2 is the highest sublevel of this first 5f-block element the actinides (89-103).
What indicates the s sublevel in the third main energy level?
The s sublevel in the third main energy level is indicated by 3s.
What is the highest sublevel electrons occupy in uranium 238?
It is the f sublevel. Uranium has the configuration [Rn] 5f3 6d1 7s2.
What is true about the electron configurations of the noble gases Decent levels are partially filled be the electrons with the highest energy you sublevel see the highest occupied SN?
The valence electron shell of noble gases is full.
