Honors Final Most Missed Questions

Front

What is the atomic number?

Back

The atomic number is the number of protons in the nucleus of an atom, which determines the element's identity.

Front

What is specific heat capacity?

Back

Specific heat capacity is the amount of heat required to raise the temperature of one gram of a substance by one degree Celsius.

Front

What is thermal equilibrium?

Back

Thermal equilibrium is the state in which two or more bodies reach the same temperature and no heat flows between them.

Front

What is electron configuration?

Back

Electron configuration is the distribution of electrons in an atom's orbitals, which determines its chemical properties.

Front

How do you determine the ratio of compounds formed by atoms?

Back

The ratio is determined by counting the number of valence electrons each atom has and how they combine to achieve stability.

Front

What is the significance of the electron configuration for ions?

Back

The electron configuration for ions shows how many electrons are lost or gained compared to the neutral atom, affecting its reactivity.

Front

What is the formula for calculating specific heat?

Back

The formula is Q = mcΔT, where Q is heat energy, m is mass, c is specific heat capacity, and ΔT is the change in temperature.

Front

What does it mean for a metal to have a specific heat capacity?

Back

It means that the metal can absorb or release heat energy without a significant change in temperature.

Front

What is the relationship between atomic number and element identity?

Back

The atomic number uniquely identifies an element; no two elements can have the same atomic number.

Front

What happens during a thermal equilibrium process?

Back

Heat transfers from the hotter object to the cooler one until both reach the same temperature.
