Which physical properties are characteristics of metals? Choose all that apply.

-brittle
-high luster
-malleable
-ductile
-not very reactive
1, 2, and 5?

I would go with bcd.

Brittle? Think of copper metal or aluminum metal. Are they brittle? No.

The physical properties that are characteristics of metals are:

- High luster (shiny appearance)
- Malleability (ability to be hammered or pressed into different shapes)
- Ductility (ability to be drawn into thin wires)
- Not very reactive

So, the correct options would be 2 and 4.

To determine which physical properties are characteristics of metals, we can go through each option provided and see if it fits the description of a metal.

1. Brittle: This property is not typical of metals. Metals are known to be malleable and ductile, meaning they can be easily bent, shaped, and stretched without breaking. So, brittle does not apply.

2. High luster: This property is indeed characteristic of metals. Metals have a unique shine or luster, which is why they are often used for decorative purposes. So, high luster applies.

3. Malleable: This property is characteristic of metals. As mentioned earlier, metals can be easily bent or shaped without breaking. So, malleable applies.

4. Ductile: This property is also characteristic of metals. Metals can be drawn into wires without breaking, which is known as being ductile. So, ductile applies.

5. Not very reactive: This property is generally true for many metals. Metals tend to have low reactivity, which means they do not easily undergo chemical reactions with other substances. So, not very reactive applies.

Therefore, the correct answer choices would be options 2 (high luster), 3 (malleable), and 5 (not very reactive).
