it is likely a gas or liquid at room temperature.
it is likely soluble in water.
it will likely light up a bulb in a conductivity apparatus.
it will likely have a high melting point.
done

Explanation:

Ionic compounds have distinct properties: they are solid at room temp, often soluble in water, conduct electricity when dissolved/molten (so they light up a conductivity apparatus), and have high melting points due to strong ionic bonds.

Answer:

• It is likely soluble in water.
• It will likely light up a bulb in a conductivity apparatus.
• It will likely have a high melting point.
