Why is the second ionisation energy of oxygen more than fluorine?
The second ionization energy of oxygen is greater than fluorine because in oxygen, after the first electron is removed, the remaining electron is from a filled shell (2p^4). This electron in oxygen experiences greater electron-electron repulsion, making it harder to remove compared to the outer electron in fluorine which is in a half-filled shell (2p^5).
What is the total number of completely filled principal energy levels in an atom of argon in the ground state?
In Neon atom the 10 electrons are present in two principal energy levels, 2 in ist and 8 in 2nd level.
How many electron shells would be completely filled by a neutral xenon atom?
A neutral xenon atom has 54 electrons. The electron configuration of xenon is [Kr] 4d^10 5s^2 5p^6, with a total of 8 completely filled electron shells (2 in the first shell, 8 in the second shell, 18 in the third shell, 18 in the fourth shell, and 8 in the fifth shell).
What is the second electron affinity of chlorine?
Chlorine has a negative second electron affinity because it releases energy when gaining an additional electron. This makes it less likely to accept a second electron compared to its first electron affinity, which is positive.
What element has the outer electron configuration 6s2 4f8?
No element has this as the ground state. Gadolinium has the right number of electrons but its ground state is [Xe] 4f7 5d1 6s2. The second number in each group should be a superscript.
How many half-filled orbitals are there in a carbon atom?
Looking at the electron configuration of carbon (at. no. 6) you have 1s2 2s2 2p2. In the 2 p subshell, you have 1 electron in the 2px orbital, and 1 electron in the 2py orbital and no electrons in the 2pz orbital. So, the answer is that there are TWO half filled orbitals in the carbon atom. This is the case BEFORE hybridization. After hybridization, there are FOUR half filled orbitals which are called sp3 hybrids.
Why is the second ionisation energy of oxygen more than fluorine?
The second ionization energy of oxygen is greater than fluorine because in oxygen, after the first electron is removed, the remaining electron is from a filled shell (2p^4). This electron in oxygen experiences greater electron-electron repulsion, making it harder to remove compared to the outer electron in fluorine which is in a half-filled shell (2p^5).
Is lithiums electron shell filled up all the way?
No. It has two shells with 2 and 1 electron each. The second shell is unfilled.
What is the total number of completely filled principal energy levels in an atom of argon in the ground state?
In Neon atom the 10 electrons are present in two principal energy levels, 2 in ist and 8 in 2nd level.
What level is filled by krypton?
The fourth electron shell is filled by krypton. Krypton is the last element in the fourth period on the periodic table. Each of the periods represents an electron shell. Elements in the first period have electrons in the first shell; elements in the second period have electrons in the second shell; and so on.
How many electron shells would be completely filled by a neutral xenon atom?
A neutral xenon atom has 54 electrons. The electron configuration of xenon is [Kr] 4d^10 5s^2 5p^6, with a total of 8 completely filled electron shells (2 in the first shell, 8 in the second shell, 18 in the third shell, 18 in the fourth shell, and 8 in the fifth shell).
What is the velocity of hydrogen in ground state?
In the ground state, hydrogen's electron does not have a well-defined velocity due to the principles of quantum mechanics. Instead, it is described by a probability cloud, with the electron's position represented by a wave function. However, if we use the Bohr model, we can approximate the electron's velocity in the ground state as about 2.18 x 10^6 meters per second. This value is derived from the electron's circular motion around the nucleus in a simplified model.
How are electron shells filled in sodium?
In sodium (Na), which has an atomic number of 11, the electron configuration is 1s² 2s² 2p⁶ 3s¹. This means that the first shell (1s) is filled with 2 electrons, the second shell (2s and 2p) is filled with 8 electrons, and the third shell (3s) contains 1 electron. Electrons fill the shells starting from the lowest energy level (1s) and move to higher levels (2s, 2p, and then 3s) until all 11 electrons are accommodated. Sodium's single valence electron in the 3s shell makes it highly reactive, as it tends to lose that electron easily.
Where are the electrons that possess the least amount of energy located in a calcium atom in the ground state?
The electrons with the least amount of energy in a calcium atom in the ground state are located in the innermost electron shell, closest to the nucleus. These electrons have lower energy levels as they are shielded by the outer electron shells.
What is the second electron affinity of chlorine?
Chlorine has a negative second electron affinity because it releases energy when gaining an additional electron. This makes it less likely to accept a second electron compared to its first electron affinity, which is positive.
Which group 18 element in the ground state has a maximum of 2 completely filled energy shells?
The group 18 element in the ground state that has a maximum of 2 completely filled energy shells is Neon (Ne). Neon has an atomic number of 10, with its electron configuration being 1s² 2s² 2p⁶. This configuration indicates that both the first energy shell (1s) and the second energy shell (2s and 2p) are fully occupied, making Neon a noble gas with stable electronic configuration.
Why does neon have a higher second ionization energy than fluorine?
Neon has a higher second ionization energy than fluorine because its first ionization energy removes an electron from a stable noble gas configuration, resulting in a very stable ion. In contrast, fluorine's second ionization energy involves removing an electron from a more unstable anion (F⁻), which is easier than removing a second electron from neon's filled outer shell. Additionally, the effective nuclear charge experienced by the remaining electrons in neon is higher, making it more difficult to remove the second electron compared to fluorine.
