To determine which pairing would create an octet for each atom, we need to consider how the atoms can share or transfer electrons to achieve a full outer shell, typically consisting of 8 electrons.
A. One Na atom (1 valence electron) and one sulfur atom (6 valence electrons):
- Sodium (Na) can donate its 1 valence electron to sulfur (S), which needs 2 more electrons to complete its octet. However, this would leave sulfur with only 7 electrons, not a full octet. Therefore, this pairing does not satisfy the octet rule for both atoms.
B. One Al atom (3 valence electrons) and one P atom (5 valence electrons):
- Aluminum (Al) has 3 valence electrons and phosphorus (P) needs 3 more electrons to complete its octet. Aluminum can donate its 3 electrons to phosphorus, allowing phosphorus to achieve an octet. However, aluminum will not have an octet after losing its electrons. Thus, this pairing does not satisfy the octet rule for both atoms.
C. Two Li atoms (1 valence electron each) and one carbon atom (4 valence electrons):
- Each lithium (Li) atom can donate its 1 valence electron. Carbon (C) needs 4 more electrons to complete its octet. With two lithium atoms donating their electrons, carbon will still be short of 2 electrons to complete its octet. Therefore, this pairing does not satisfy the octet rule for both atoms.
D. One K atom (1 valence electron) and 10 O atoms (6 valence electrons each):
- Potassium (K) can donate its 1 valence electron to one oxygen (O) atom, which needs 2 electrons to complete its octet. However, even if potassium donates its electron, it will not fulfill the octet requirement for any of the oxygen atoms, as they require 2 electrons each. This pairing does not satisfy the octet rule for both atoms.
None of the given pairings result in an octet for each atom involved.
