Assuming the electron is in the lowest states and the atom is neutrally charged, it will fill an orbital before extending the next one.
1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p, 5s, 4d, 5p, 6s, 4f, 5d, 6p, 7s, 5f, 6d, 7p
H and He fill 1s as it holds two electrons.
Li and Be fill 2s as it holds two electrons.
B, C, N, O, F, and Ne will fill the 2p orbital as it holds 6 electrons (2p1, 2p2, and 2p3 orbitals).
However, nitrogen will have one electron in each 2p1, 2p2, and 2p3 orbitals as an electron will not go two to an orbital until each orbital is filled.
Neon completes the 2p orbital and is very stable (considered an inert gas--electrons are neither attracted nor want to leave the completed 2p orbital). Fluorine is the most electronegative element, as it wants to rip any electron it can to fill its 2p orbital.
All noble gasses (right most on the Periodic Table) will complete a p-orbital.
Periods 3-12 will fill a d-orbital.
Lanthanoids and actinoids will fill the f-orbitals.
So, for instance, Calcium (Ca) has an atomic number 20. You look up Ca on the periodic table.
As it comes after He, it will have a 1p orbital filled.
As it comes after Be, it will have a 2s orbital filled.
As it comes after Ne, it will have a 2p orbital filled.
And Ca will have a 3s orbital filled.
Therefore, you note that Ca has electrons in the following orbitals: 1s, 2s, 2p, 3s.
Another example is Fluorine (F), which would be: 1s, 2s, 2p1(2), 2p2(2), 2p3(1) where the parenthetical numbers note the number of electrons in each orbital.
What else can I help you with?
What do you call an atom if you move an electron in an atom from a low energy level to a higher energy level within the atom?
When you move an electron in an atom from a lower energy level to a higher energy level, it is called an electron excitation. This process requires the electron to absorb energy to move to a higher energy state.
When an electron jumps to a higher level is the atom is in ground state?
No, when an electron jumps to a higher energy level, the atom is said to be in an excited state. The ground state of an atom is when its electrons occupy the lowest possible energy levels.
How the concept of ionization energy of H-atom can be justify from bohr model of atom?
In the Bohr model of the hydrogen atom, the electron is assumed to orbit the nucleus in discrete energy levels. The ionization energy of the hydrogen atom corresponds to the energy required to completely remove the electron from its orbit, moving it from its lowest energy level to an unbound state. This energy depends on the specific energy level the electron is in, as each energy level has a corresponding ionization energy.
What is energy released on adding an electron to an isolated gas phase atom?
The energy released on adding an electron to an isolated gas phase atom is called electron affinity. It represents the willingness of an atom to accept an additional electron. The process can release energy if the atom's electron affinity is negative, indicating that the atom is stable after gaining an electron.
When the electron emits lights does the electron move up to a higher energy level or down to a lower energy level?
In the Bohr model of the atom, an electron emits a photon when it moves from a higher energy level to a lower energy level.
What do you call an atom if you move an electron in an atom from a low energy level to a higher energy level within the atom?
When you move an electron in an atom from a lower energy level to a higher energy level, it is called an electron excitation. This process requires the electron to absorb energy to move to a higher energy state.
What state is an atom in which an electron has moved to a higher energy level?
An atom in which an electron has moved to a higher energy level is in an excited state. This can happen when the electron absorbs energy from its surroundings, such as from light or heat. The electron will eventually return to its original energy level, releasing the absorbed energy as light.
How can an electron in an atom lose energy to transition from a higher energy level to a lower energy level?
An electron in an atom can lose energy to transition from a higher energy level to a lower energy level by emitting a photon of light. This process is known as emission.
How much energy is required to ionize a hydrogen atom containing an electron in the n4 level?
The energy required to ionize a hydrogen atom with an electron in the n4 level is 0.85 electron volts.
A - 1s22s22p63s1 B - 1s22s22p65s1 What is the difference between atom A and atom B?
The electron configurations provided represent the electron arrangement in the outermost energy level of the atoms. Atom A has a 3s1 electron configuration, indicating it is in the third energy level with one electron in the s orbital. Atom B, on the other hand, has a 5s1 electron configuration, indicating it is in the fifth energy level with one electron in the s orbital. Therefore, the main difference between atom A and atom B is the energy level in which their outermost electrons reside.
What happens when an atom absorbs ultraviolet energy and an electron is involved?
When an atom absorbs ultraviolet energy and an electron is involved, the electron can move to a higher energy level or be ejected from the atom, leading to the atom becoming ionized or excited.
What is an electron in an atoms outer most energy level?
The electrons on the outtermost energy level of an atom is called a valence electron.
What are the highest energy level electron of atom called?
The highest energy level is called the "electronegativity".
What is the energy level of the atom Xenon?
Xenon has multiple energy levels associated with its electron configuration. The energy level of an atom is typically determined by the arrangement of electrons in its electron shells. Depending on the state of the xenon atom (neutral, ionized, excited, etc.), its energy level can vary.
Can an electron in the outer energy level be called a valence electron?
Yes, an electron in the outermost energy level of an atom is called a valence electron. Valence electrons are involved in chemical bonding and determining the reactivity of an atom.
Which quantum number represents the main energy level of an electron?
The principal quantum number (n) represents the main energy level of an electron in an atom. It determines the energy level and distance of the electron from the nucleus.
What is the valence electron number in an atom?
the number of electrons in the 3rd energy level of an atom.
