1. State Aufbau's rule.
2. Which sub shell is filled first ?
3.how many electrons can fit in an s orbital?
4. How many electrons can fit in a p orbital?
5. How many electrons can fit in a d orbital?
6. How many electrons can fit in an f orbital?
7. What is hund's rule?
8. Why do electrons maximize the number of unpaired electrons?
1. Aufbau's rule states that electrons fill orbitals with lower energy levels first before filling higher energy levels.
2. The s subshell is filled first.
3. In an s orbital, a maximum of 2 electrons can fit.
4. In a p orbital, a maximum of 6 electrons can fit.
5. In a d orbital, a maximum of 10 electrons can fit.
6. In an f orbital, a maximum of 14 electrons can fit.
7. Hund's rule states that when filling orbitals of the same energy level, electrons will occupy separate orbitals of the same energy before pairing up in the same orbital.
8. Electrons maximize the number of unpaired electrons because it is energetically favorable. Having unpaired electrons means that they have the same spin, and this increases the stability of the electron configuration.
1. Aufbau's rule states that electrons fill atomic orbitals in order of increasing energy, with the lowest energy orbitals being filled first.
2. The subshell filled first is the 1s subshell.
3. An s orbital can hold a maximum of 2 electrons.
4. A p orbital can hold a maximum of 6 electrons.
5. A d orbital can hold a maximum of 10 electrons.
6. An f orbital can hold a maximum of 14 electrons.
7. Hund's rule states that when electrons are filling degenerate (same energy) orbitals, they will first occupy empty orbitals before pairing up in the same orbital. This results in the maximum number of unpaired electrons.
8. Electrons maximize the number of unpaired electrons because having unpaired electrons leads to greater stability and lower energy. When electrons are unpaired, they can more easily participate in chemical bonding and interactions with other atoms or molecules.
1. Aufbau's rule states that electrons fill the lowest energy orbitals first before moving to higher energy orbitals when constructing the electron configuration of an atom.
2. The subshell that is filled first is the 1s subshell, which has the lowest energy level.
3. An s orbital can hold a maximum of 2 electrons.
4. A p orbital can hold a maximum of 6 electrons.
5. A d orbital can hold a maximum of 10 electrons.
6. An f orbital can hold a maximum of 14 electrons.
7. Hund's rule states that when electrons occupy orbitals of equal energy (such as the p, d, or f orbitals), they will first occupy each orbital singly, with parallel spins, before pairing up with opposite spins.
8. Electrons maximize the number of unpaired electrons because having unpaired electrons gives an atom a higher magnetic moment and makes it more reactive. It is energetically favorable for electrons to occupy different orbitals with parallel spins rather than pairing up in the same orbital with opposite spins, as there is a repulsion between electrons of the same spin.
