Analyzing Atomic Structures in Bohr Models

Front

What does the nucleus represent in a Bohr model?

Back

The nucleus is the central part of an atom, containing protons and neutrons.

Front

What is the mass number of an atom?

Back

The mass number is the total number of protons and neutrons in the nucleus of an atom.

Front

In which sublevel are the three valence electrons of Aluminum (Al) found?

Back

The three valence electrons of Aluminum (Al) are found in the s-and-p-sublevels.

Front

How many valence electrons does Sodium have in its Bohr model?

Back

Sodium has 1 valence electron in its Bohr model.

Front

What is the significance of valence electrons?

Back

Valence electrons determine an atom's chemical properties and its ability to bond with other atoms.

Front

What does the electron cloud represent in atomic structure?

Back

The electron cloud represents the regions around the nucleus where electrons are likely to be found.

Front

How do you determine the number of protons in an atom?

Back

The number of protons in an atom is equal to its atomic number.

Front

What is the difference between an atom's atomic number and mass number?

Back

The atomic number is the number of protons, while the mass number is the total number of protons and neutrons.

Front

What element is represented by the Bohr model with 11 protons?

Back

The element with 11 protons is Sodium (Na).

Front

What is the role of neutrons in an atom?

Back

Neutrons contribute to the mass of the atom and help stabilize the nucleus.
