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 the first electron affinity is negative?
The electron affinity, or EA, of nitrogen is less than zero (EA = -7) because of is electron configuration, which is [He] 2s2 2p3. Nitrogen, as a neutral atom has a half-filled p-orbital, and by Hund's Rule, that means that each p-orbital has 1 unpaired electron. In the same way that a completely filled orbital is especially stable (like the noble gases), a half-filled orbital IN A NITROGEN ATOM IS HIGHLY UNSTABLE ([He] 2s2 2p4).In contrast, carbon, C, has a much larger electron affinity (EA = -123.4 kJ/mol) because it has electron configuration [He] 2s2 2p2, which means that the addition of one more electron will bring it to an extra stable half-filled shell. Fluorine of course has an extremely high electron affinity (EA = -331.4 kJ/mol) because of it's electron configuration, [He] 2s2 2p5, where the addition of one more electron gives it a completely filled valence shell or noble gas configuration, [He] 2s2 sp6.
Which has higher eleetron affinity between nitrogen and carbon?
Nitrogen has a higher electron affinity than carbon. This is because nitrogen, being in Group 15 of the periodic table, has one additional electron in its p orbital compared to carbon, which is in Group 14. Therefore, nitrogen has a greater tendency to accept an additional electron to achieve a stable electron configuration.
When will an atom give up an electron?
An atom will give up an electron when it is more stable by achieving a full outer electron shell. This typically occurs when the atom is in an ionic bond or is trying to achieve a more stable electron configuration.
Why 4s has one electron and 3d has 5 electrons?
In some cases, electron configurations will break the diagonal rule. This is because electron shells are most stable when fully filled or half-filled. Since the 3d sublevel can hold up to 10 electrons, 3d would be most stable with 10 or 5 electrons. To make this happen, an electron must move from the previous sublevel (4s) into the 3d sublevel. Consequently, both shells now have half-filled electron configurations. You should never take two electrons away from an s-shell to make a d-shell half full because then there would be more than 8 valence electrons (13, in fact), which is a hefty violation of the octet rule.

Why the electron affinities of beryllium and nitrogen are positive?
In general, elements attract electrons because they have positively charged nuclei, and although they also have negatively charged electron shells, the electrons are very mobile and they adjust themselves so that they have the minimum effect on other electrons while remaining as close as possible to the nucleus (a constant balancing act). The specific degree to which a given element will attract electrons is strongly influenced by the kind of electron configuration that the element has. Nitrogen, which can form a complete outer shell by acquiring another 3 electrons, has a much stronger attraction for electrons than beryllium has, since beryllium can more easily get to a complete outer shell by losing electrons than it can by gaining them.
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).
Does insulator half filled valence shell?
No but your mom does

Are atoms most stable when they have partially filled shells?
No, atoms are most stable when their outermost electron shells are completely filled. This is because a full outer shell results in a lower energy state, making the atom more stable. Partially filled shells can lead to greater reactivity as atoms seek to fill or empty their outermost shell.
Which element has a half-filled 3s orbital in the ground state?
The element with a half-filled 3s orbital in the ground state is Sodium (Na). Its electron configuration is 1s2 2s2 2p6 3s1, which means the 3s orbital is half-filled with one electron.
Why ionization potential of nitrogen is more than oxygen?
nitrogen has higher ie than oxygen because of thd half filled p-orbital ie. 1s2 2s2 2p6 hence more enery is required to remove the electron from the orbital nitrogen has more ie than carbon because as we move along a period the ie increase becausean.electron is added to the valence shell
How many half-filled orbitals are in a sulfur atom?
Sulfur has 4 half-filled orbitals, which are the three 3d orbitals and the 4s orbital. An orbital is considered half-filled when it contains one electron.
What is the difference between a stable and unstable electronic configuration?
Stable electronic configuration is when the valence shell of an element is completely filled (8 electrons) whereas unstable electronic configuration is when the valence shell of an element is not completely filled
