Front

What is the process called when a liquid changes to a gas?

Back

Evaporation is the process where a liquid changes into a gas, typically occurring at the surface of the liquid.

Front

Which element has the greatest ionization energy: Aluminum (Al) or Chlorine (Cl)?

Back

Chlorine (Cl) has the greatest ionization energy compared to Aluminum (Al). Ionization energy is the energy required to remove an electron from an atom.

Front

What is the boiling point of a substance if its heating curve shows a transition at 60°C?

Back

The boiling point of the substance is 60°C, which is the temperature at which it changes from liquid to gas.

Front

What does the number 6 represent in the notation of Carbon (C)?

Back

The number 6 represents the Atomic Number of Carbon (C), which indicates the number of protons in its nucleus.

Front

What family of elements does silver belong to?

Back

Silver is part of the Transition Metals family, which are known for their ability to conduct electricity and heat.

Front

Define ionization energy.

Back

Ionization energy is the amount of energy required to remove an electron from an atom in its gaseous state.

Front

What is the difference between evaporation and condensation?

Back

Evaporation is the process of a liquid turning into a gas, while condensation is the process of a gas turning back into a liquid.

Front

What is a heating curve?

Back

A heating curve is a graph that shows the temperature of a substance as it is heated over time, illustrating phase changes.

Front

What are Transition Metals?

Back

Transition Metals are elements found in groups 3-12 of the periodic table, characterized by their ability to form variable oxidation states.

Front

What is the significance of the atomic number?

Back

The atomic number of an element determines its identity and the number of protons in its nucleus.
