What else can I help you with?
A certain oxygen atom has the electron configuration 1s2 2s2 2px2 2py2 How many unpaired electrons are present?
There are four unpaired electrons present in this oxygen atom. Each of the 3 p orbitals (2px, 2py, 2pz) contains one unpaired electron, and the 2s orbital has two unpaired electrons.
Which rule is violated in the configuration of 1s2 2s2 2px2?
Hund's rule is violated in this configuration. According to Hund's rule, electrons will fill empty orbitals before pairing up in the same orbital. In this case, the electrons should have filled the 2py and 2pz orbitals first before pairing up in the 2px orbital.
How many orbitals completely filled in an atom whose wlectron configuration is 1s2 2s2 2p6 3s1?
That would be 1s2, 2s2, 2p6 are the 3 orbitals that are completely filled. The other one is not filled because it only has 1 configuration. Hopefully this help....if not I apologize. *PUMA #4*
What types of atomic orbitals are in the second principal energy level?
An s orbital
In earth chemistry which elements has the same number of electron orbitals as the element sodium?
The elements in the same period as sodium on the periodic table have the same number of electron orbitals. So, phosphorus, sulfur, chlorine, argon, potassium, calcium, and scandium would all have the same number of electron orbitals as sodium.
How many equal energy p orbitals?
three...2px,2py,and 2pz.
Does the 2nd principal energy level contain 4 orbitals?
Yes. The 2s, 2px, 2py and 2pz .

What is the valence shell for nitrogen?
Nitrogen (N) has atomic number 7. It has full 1s and 2s orbitals. The 2px orbital has 1 electron, the 2py orbital has 1 electron and the 2pz orbital has 1 electron. So the valence shell is: 2s2 - 2p3. It contains 5 electrons.
What are the postulates of molecular orbit theory?
Molecular Orbital Theory (MOT):•Basic idea of MOT is that atomic orbitals of individual atoms combine toform molecular orbitals. Electrons in molecule are present in themolecular orbitals which are associated with several nuclei.•The molecular orbital formed by the addition of atomic orbitals is calledthe bonding molecular orbital (s ).•The molecular orbital formed by the subtraction of atomic orbital is calledanti-bonding molecular orbital (s*).•The sigma (s ) molecular orbitals are symmetrical around the bond-axiswhile pi (p ) molecular orbitals are not symmetrical.•Sequence of energy levels of molecular orbitals changes for diatomicmolecules like Li2, Be2, B2, C2, N2 is 1s < *1s < 2s< *2s < ( 2px = 2py)
What is the energy level and orbital for K?
Assuming K stands for potassium, an element with 19 electrons, the electron configuration is as follows: 1s2 2s2 2p6 3s13p64s1 The electron configuration shows the orbitals is order of energy level. The 4s orbital being at the highest energy level and the 1s orbital being at the lowest energy level. As 2px, 2py and 2pz exist, there are three 2p orbitals that occur at the p level, allowing the element to carry 6 electrons, 2 in each orbital. There is a specific order in listing the orbitals
What types of atomic orbitals are in the second principal energy level?
An s orbital
What is 2s and 2p?
The terms 2s and 2p refer to specific atomic orbitals in the second energy level (n=2) of an atom. The 2s orbital is a spherical shape and can hold a maximum of two electrons, while the 2p orbitals consist of three dumbbell-shaped regions (2px, 2py, and 2pz) and can collectively hold up to six electrons. Together, these orbitals help define the electron configuration and chemical behavior of elements in the second period of the periodic table.
In earth chemistry which elements has the same number of electron orbitals as the element sodium?
The elements in the same period as sodium on the periodic table have the same number of electron orbitals. So, phosphorus, sulfur, chlorine, argon, potassium, calcium, and scandium would all have the same number of electron orbitals as sodium.
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.
