An element belongs to third period and group 13 of the periodic table which of the following properties will be shown by the element?

Options

A. good conductor of electricity
B. liquid ,non metallic
C. solid,non metallic
D. All of these

Answer

To determine the properties of an element that belongs to the third period and group 13 of the periodic table, we can follow these steps:

### Step 1: Identify the Element
- The element in the third period and group 13 of the periodic table is Aluminium (Al).

### Step 2: Classify the Element
- Aluminium is classified as a metal. Metals are typically solid at room temperature, with some exceptions (like mercury).

### Step 3: Determine Conductivity
- Metals, including Aluminium, are known to be good conductors of heat and electricity. This is due to the presence of free electrons in their lattice structure, which allows for the easy flow of electricity and heat.

### Step 4: Summarize the Properties
- Since Aluminium is a metal, we can summarize its properties:
- It is solid at room temperature.
- It is a good conductor of electricity and heat.

### Conclusion
- Therefore, the property that will be shown by the element (Aluminium) is that it is a good conductor of electricity.
