Question

The following are properties of various elements. Drag each property into the correct box in order to identify the element as a metal or a nonmetal.

1. Element 1:
- Gas at room temperature

2. Element 2:
- Solid that conducts electricity

3. Element 3:
- Gas with an effective nuclear charge of 7

4. Element 4:
- Malleable and can take the form of a shiny, solid sheet

Answer 1

Element 1 and Element 3 are classified as nonmetals because they are gases at room temperature. Element 2 and Element 4 are classified as metals because they are solid at room temperature and have properties like electrical conductivity and malleability.

Step-by-step explanation:

The properties described in the question can be used to classify elements as either metals or nonmetals. To determine the classification for each element:

• Element 1: Gas at room temperature. This property is typical of nonmetals, as many nonmetals are found as gasses at room temperature.
• Element 2: Solid that conducts electricity. These are properties of metals, which are usually solid at room temperature and good conductors of electricity.
• Element 3: Gas with an effective nuclear charge of 7. Without more context, this property alone is insufficient to classify as a metal or nonmetal, but gasses are commonly associated with nonmetal elements.
• Element 4: Malleable and can take the form of a shiny, solid sheet. This description fits the characteristics of a metal, which are malleable and typically have a shiny appearance.
