Which energy levels do not have p orbital?
The energy levels that do not have p orbitals are the first and second energy levels. The first energy level (n=1) contains only an s orbital, while the second energy level (n=2) has both s and p orbitals. Starting from the third energy level (n=3), s, p, and d orbitals are present.
Why is there no transition elements in the first 3 periods?
Transition elements are defined as d-block elements, which have partially filled d orbitals. In the first three periods of the periodic table (1-3), the electron configurations fill the s and p orbitals without any d orbitals being involved. The first d-block elements appear in the fourth period, beginning with scandium (Sc), where the 3d orbitals start to fill. Thus, there are no transition elements in the first three periods.
The first period in the periodic table represents elements that possess only the first energy level s orbital therefore this period contains?
Two elements
Why do d orbital start to fill?
d orbitals begin to fill after the s orbitals of the same principal energy level are filled, specifically starting from the 3d orbitals after the 4s orbital. This occurs due to the energy levels of the orbitals; while the 4s orbital is filled before the 3d, the 3d orbitals have a higher energy level compared to 4s once the 3s and 3p orbitals are filled. As electrons are added to an atom, they occupy the lowest available energy orbitals first, which is why d orbitals fill after the s and p orbitals of the preceding energy level.
The order in which atomic orbitals are filled is based on what factor?
It is based on many factors, but the easiest to understand is ENERGY. The orbitals in which the electron has the lowest energy are filled FIRST.
What column contains elements whose electron configuration end with d4?
The column that contains elements whose electron configuration ends with d4 is the "transition metals" column. Transition metals have partially filled d orbitals in their electron configurations, typically with the d orbitals being filled first before the s and p orbitals.
Which energy levels do not have p orbital?
The energy levels that do not have p orbitals are the first and second energy levels. The first energy level (n=1) contains only an s orbital, while the second energy level (n=2) has both s and p orbitals. Starting from the third energy level (n=3), s, p, and d orbitals are present.
How are orbitals and energy levels related?
The principal quantum number, n, designates the main energy levels occupied by electrons. The number of orbitals in an energy level is n2 (n squared), so that the first energy level, n = 1, contains 1 orbital; the second energy level, n = 2, contains 4 orbitals; the third energy level, n= 3, has 9 orbitals; and the fourth energy level, n=4, has 16 orbitals, and so on.
How many orbitals does sulfur have?
Sulfur has three electron orbitals. The first orbital contains 2 electrons, the second contains 8 and the third contains 6.

The first period in the peroidical table represents elements that possese elements only the first energy level is orbital thefore this perid contains?
two elements, hydrogen and helium.
What are the electron levels?
Electrons don't have levels. They have shells and orbitals. Each shell contains certain orbitals. For example, the first shell contains only the s orbital. The second contains the s and p orbital. The fourth shell has the s, p, and d orbitals.
The first period in the periodic table represents elements that possess only the first energy level s orbital therefore this period contains?
Two elements

Why does the s orbital fill before the p orbitals?
The s orbital is lower in energy than the porbital.
