Front

What does the Bohr model represent in atomic structure?

Back

The Bohr model represents the structure of an atom, depicting electrons orbiting the nucleus in defined paths or energy levels.

Front

What element is represented by the Bohr model with 3 electrons?

Back

Lithium.

Front

What happens to ionization energy as it becomes harder to remove a valence electron?

Back

Ionization energy increases.

Front

What occurs when a substance dissolves in water?

Back

The substance breaks down into its components but remains present in the solution.

Front

What type of bond is formed by the attraction between cations and anions?

Back

Ionic bond.

Front

How does atomic radius affect the ease of removing a valence electron?

Back

A larger atomic radius makes it easier to remove a valence electron.

Front

Define ionization energy.

Back

Ionization energy is the energy required to remove an electron from an atom or ion.

Front

What is a cation?

Back

A cation is a positively charged ion formed when an atom loses one or more electrons.

Front

What is an anion?

Back

An anion is a negatively charged ion formed when an atom gains one or more electrons.

Front

Explain the difference between ionic and covalent bonds.

Back

Ionic bonds involve the transfer of electrons between atoms, while covalent bonds involve the sharing of electrons.
