Atomic Structure and Electron Behavior June 24

Front

What happens to an atom when it absorbs energy?

Back

The atom transitions from a ground state to an excited state.

Front

What is the balanced equation for the combustion of carbon monoxide?

Back

2CO(g) + O2(g) → 2CO2(g) + energy.

Front

What property allows the separation of water and sand using filter paper?

Back

Particle size.

Front

What is an orbital in the context of the electron cloud model?

Back

An orbital is defined as the most probable location of an electron in an atom.

Front

What do the coefficients in a balanced chemical equation represent?

Back

Mole ratios of the reactants and products.

Front

What is the ground state of an atom?

Back

The lowest energy state of an atom where electrons are in their closest orbitals to the nucleus.

Front

What is an excited state of an atom?

Back

A state where an atom has absorbed energy and electrons are in higher energy levels.

Front

How do you calculate the mass of a reactant in a chemical reaction?

Back

Use the mole ratios from the balanced equation to relate the masses of reactants and products.

Front

What is the significance of particle size in mixtures?

Back

It determines the method of separation, such as filtration.

Front

What is the definition of a chemical reaction?

Back

A process where reactants are transformed into products, involving the breaking and forming of bonds.
