Which two elements exhibit similar chemical bonding patterns due to having the same number of valence electrons?
A
Magnesium (Mg) and Aluminum (Al)
B
Sodium (Na) and Potassium (K)
C
Carbon (C) and Nitrogen (N)
D
Oxygen (O) and Neon (Ne)
Verified step by step guidance1
Understand that elements with the same number of valence electrons tend to exhibit similar chemical bonding patterns because valence electrons determine how atoms interact and bond.
Identify the group (column) of each element in the periodic table to find their valence electron count. Elements in the same group have the same number of valence electrons.
Magnesium (Mg) is in group 2 with 2 valence electrons, Aluminum (Al) is in group 13 with 3 valence electrons, so they do not have the same valence electron count.
Sodium (Na) and Potassium (K) are both in group 1, meaning they each have 1 valence electron, which explains their similar bonding behavior.
Carbon (C) and Nitrogen (N) have different valence electrons (4 and 5 respectively), and Oxygen (O) and Neon (Ne) differ as well (6 and 8 respectively), so they do not exhibit similar bonding patterns.
