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.
What is the lowest energy main shell that surround the molecules?
The lowest energy main shell that surrounds molecules is the first main shell, also known as the K shell. It is closest to the nucleus and can hold up to 2 electrons.
What is the atomic sublevel with the next highest energy after 4p?
The next highest energy atomic sublevel after 4p is the 5s sublevel. In the electron configuration of an atom, energy levels increase with increasing principal quantum number (n), so the 5s sublevel is higher in energy than the 4p sublevel.
What sub level s of energy make the o shell?
The sub-level s of energy that make the o shell is the K-shell.
What principle energy level has no F sublevel?
The second principle energy level (n=2) does not have an F sublevel. The F sublevel belongs to the third principle energy level (n=3) and higher energy levels.
Which energy sublevel is being filled by the element K to Ca?
4s. Both K and Ca are s block and they are both in the 4th period. So in K, you have 4s1 and in Ca you have 4s2

What is phosphorus' sublevel?
Phosphorus typically fills its outermost electron shell in the third energy level, or s sublevel, in its ground state configuration.
What is the lowest numbered energy level where a d sublevel is found?
The lowest numbered energy level where a d sublevel is found is the third energy level. Energy levels are represented by numbers (1, 2, 3, etc.) and each level can contain sublevels corresponding to different types of orbitals (s, p, d, f).
What is the k-shell binding energy for rhodium?
The k-shell binding energy for rhodium, which is an element with atomic number 45, is approximately 23.44 keV.
What is the term for an electron energy level that results from splitting a main energy level?
energy sublevel
What is the lowest energy main shell that surround the molecules?
The lowest energy main shell that surrounds molecules is the first main shell, also known as the K shell. It is closest to the nucleus and can hold up to 2 electrons.
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 atomic sublevel with the next highest energy after 4p?
The next highest energy atomic sublevel after 4p is the 5s sublevel. In the electron configuration of an atom, energy levels increase with increasing principal quantum number (n), so the 5s sublevel is higher in energy than the 4p sublevel.
What is the first shell closest to the nucleus?
The K shell is first shell closest to the nucleus.
What sub level s of energy make the o shell?
The sub-level s of energy that make the o shell is the K-shell.
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.
