Questions & Step-by-Step Solutions
Which of the following molecules is isoelectronic with Ne?
Step 1: Understand what 'isoelectronic' means. Isoelectronic means that two or more molecules or ions have the same number of electrons.
Step 2: Determine the number of electrons in Neon (Ne). Neon is a noble gas and has 10 electrons.
Step 3: Look for other molecules or ions that also have 10 electrons. In this case, we will check N2.
Step 4: Calculate the number of electrons in N2. Each nitrogen atom (N) has 7 electrons, and since N2 has two nitrogen atoms, it has a total of 7 + 7 = 14 electrons. However, N2 is a diatomic molecule and shares electrons, so we need to consider the bonding.
Step 5: In N2, there are 3 bonding pairs of electrons (6 electrons) and 2 lone pairs (2 electrons) on each nitrogen atom, which gives a total of 10 valence electrons that are effectively counted for isoelectronic comparison.
Step 6: Since both Ne and N2 have 10 effective electrons, we conclude that N2 is isoelectronic with Ne.
