Question

compounds can be classified as covalent or ionic by noting the location on the periodic table for each atom in the compound. which compound is covalently bonded?

• sodium chloride (nacl)
• sulfur dioxide (so₂)
• potassium bromide (kbr)
• magnesium chloride (mgcl₂)

Explanation:

Covalent bonds form between non - metals. Sulfur (S) and oxygen (O) are non - metals. Sodium (Na), potassium (K), magnesium (Mg) are metals. Chlorine (Cl), bromine (Br) are non - metals, but in NaCl, KBr, MgCl₂, the bonds are ionic (metal + non - metal). SO₂ has a covalent bond (non - metal + non - metal).

Answer:

sulfur dioxide (SO₂)
