___________are elements that receive or gain electrons to produce negative ions.
- Non-metals
- Metals
- Metalloids
- Noble gases
Hint:
Hydrogen, chlorine, fluorine, carbon, nitrogen, phosphorus, and selenium are some examples for non-metals
The correct answer is: Non-metals
- A non-metal is one that lacks all metallic properties.
- They are excellent thermal and electrical insulators.
- Most are gases, some are liquids. Some of these are solid even at room temperatures, such as carbon, sulfur, and phosphorus.
- Non-metals are characterized by high ionization energy and high electronegativity. Because of these properties, nonmetals usually gain electrons when reacting with other compounds to form covalent bonds.
- An element that receives or gains electrons to generate negative ions.
