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 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.
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.
If an electron is in the second energy level in which type of orbitals could this electron be in?
If an electron is in the second principle energy level, that is, n = 2, then that electron could be in an s or p orbital.
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.
Why the second ionization energy of Ca is lower than the second ionization energy of k?
Because with the 2nd ionisation of K, you are trying to take an electron from a fully filled orbital (octet rule) whereas with calcium it is getting down to a fully filled orbital
How many electron levels in neon?
Neon is in period 2, so it has two main levels.
