BaO

KI

NaBr

SiO2

Answer 1

si o2

Step-by-step explanation:

took the test and got it correct

Answer 2

SiO2

Step-by-step explanation:

• Non-metals are elements that react by gaining electron(s) to attain a stable configuration and form an anion.
• Unlike metals, non-metals are characterized by being poor conductors of heat and electricity.
• In this case, the formula that contains non-metals is SiO2, it contains silicon and oxygen which are both non-metals.

• The other choices contain a metal and a non-metal

1. BaO - Contains Barium metal and Non-metal, Oxygen
2. KI - Contains potassium metal and Non-metal, iodine
3. NaBr - Contains sodium metal and non-metal, Bromine
