Question

Based on their locations in the periodic table, which two elements are most likely to form
covalent bonds with each other?
(1 point)
sodium (Na) and bromine (Br)
magnesium (Mg) and sulfur (S)
nitrogen (N) and oxygen (O)
potassium (K) and iodine (I)

Answer 1

Covalent bonds are typically formed between nonmetals, where atoms share electrons, rather than between metals and nonmetals, which usually form ionic bonds.

1. Sodium (Na) is a metal and bromine (Br) is a nonmetal.
2. Magnesium (Mg) is a metal and sulfur (S) is a nonmetal.
3. Nitrogen (N) and oxygen (O) are both nonmetals.
4. Potassium (K) is a metal and iodine (I) is a nonmetal.

Among these options, the pair that is most likely to form covalent bonds is **nitrogen (N) and oxygen (O)**, as both elements are nonmetals and can share electrons to form covalent bonds.
