Only one electron in the highest-energy s sublevel in the ground state are called?
Alkali metals
What is the atomic sublevel with the next highest energy after 4p?
5s
When comparing the energy of an electron in the 3d sub-level to that of an electron in the 4s sublevel of the same atom?
They are both capable of holding a maximum of 10
What is the highest occupied energy sublevel for Strontium?
Answer. 4sCa = Calcium Atomic number is 20, that means it has 20 proton and 20 electron.1s2,2s2,2p6,3s2,3p6,and 4s2, total of 20 electrons, therefore Highest occupied energy level of Ca is 4s
Why does the 4S orbital begin to fill before the 3D orbital?
Electrons occupy orbitals in a definite sequence, filling orbitals with lower energies first. Generally, orbitals in a lower energy level have lower energies than those in a higher energy level. But, in the third level the energy ranges of the principal energy levels begin to overlap. As a result, the 4s sublevel is lower in energy than the 3d sublevel, so it fills first.
Only one electron in the highest-energy s sublevel in the ground state are called?
Alkali metals
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.
What is the second quantum number for the electrons in the 4p energy sublevel of bromine?
The second quantum number (l) for the electrons in the 4 p energy sublevel of bromine would be 1.
What is the atomic sublevel with the next highest energy after 4p?
5s
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
What is energy sublevel?
The level of energy possessed by all electrons in one type of orbital
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 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.
Why is it that all of the sub shells in a given shell have the same energy in the hydrogen atom whereas in a many-electron atom the sub shells in a given shell do not have the same energy?
The hydrogen atom only has one energy level (shell). The first energy level also contains only one sublevel, 1s sublevel (subshell), which can only hold two electrons. When you get to the second energy level in the second period on the periodic table, it has two sublevels, the 2s and the 2p sublevels. Both of the electrons in the 2s sublevel have the same energy. The 2p sublevel can hold 6 electrons. All of the electrons in the 2p sublevel have the same energy, which is higher than the energy in the 2s sublevel. So, as we move down the periods on the periodic table, we move from the first energy level to the seventh energy level. Each energy level contains specific numbers of sublevels, and all of the atoms within a particular sublevel have equal energy.
What is the correct electron configuration for an element with 5 electrons in the 3d energy sublevel?
1s22s22p63s23p64s23d5
How many 2p orbitals are there and what is the number of electrons they can hold?
There are three 2p orbitals and each can hold a maximum of two electrons with opposite spins, for a total of 6 electrons. This is true of the p sublevel in any energy level, except for the first energy level, which does not have a p sublevel.
When comparing the energy of an electron in the 3d sub-level to that of an electron in the 4s sublevel of the same atom?
They are both capable of holding a maximum of 10
