Predicting bond type (metals vs. nonmetals) | AP Chemistry | Khan Academy

TL;DR

Metals conduct electricity, are malleable, and solid at room temperature, while nonmetals are often gases, do not conduct electricity well, and are divided from metals by a yellow line on the periodic table.

Transcript

• [Instructor] In a previous video, we introduced ourselves to the idea of bonds between atoms, and we talked about the types of bonds, ionic, covalent and metallic. In this video we're going to dig a little bit deeper and talk about the types of bonds that are likely to be formed between different elements. And to understand that, I'm going to int... Read More

Key Insights

• 🤘 Metals conduct electricity, are malleable, and solid at room temperature.
• 🫢 Nonmetals are often gases, do not conduct electricity well, and are not solid at room temperature.
• 🫢 Noble gases are a subclass of nonmetals and are inert.
• 🤘 Metalloids have properties of both metals and nonmetals.
• 🫥 The yellow line on the periodic table separates metals from nonmetals.
• 🤘 When a metal and a nonmetal bond, it forms an ionic bond.
• 💁 When two nonmetals bond, it forms a covalent bond.

Questions & Answers

Q: What are the properties of metals?

Metals conduct electricity, are malleable, and solid at room temperature. However, there are exceptions to these properties.

Q: What are the properties of nonmetals?

Nonmetals are often gases, do not conduct electricity well, and are not solid at room temperature. However, exceptions exist for these properties as well.

Q: How are metals and nonmetals divided on the periodic table?

A yellow line on the periodic table separates metals from nonmetals. Elements above and to the right of this line are nonmetals, while elements below the line are generally considered metals.

Q: What are metalloids?

Metalloids, represented by elements in the bluish-green color on the periodic table, have properties that straddle both metals and nonmetals. They are sometimes referred to as semimetals.

Summary & Key Takeaways

• Metals conduct electricity, are malleable, and solid at room temperature.

• Nonmetals are often gases, do not conduct electricity well, and are not solid at room temperature.

• Nonmetals and noble gases are divided from metals by a yellow line on the periodic table.
