Bohr Model

Front

What is the Bohr Model?

Back

The Bohr Model is a theory of atomic structure that depicts the atom as a small, positively charged nucleus surrounded by electrons that travel in circular orbits around the nucleus.

What does the atomic number represent?

Back

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

How many electrons can the first energy level hold according to the Bohr Model?

Back

The first energy level can hold a maximum of 2 electrons.

Front

What is a valence electron?

Back

Valence electrons are the electrons in the outermost shell of an atom that are involved in forming bonds with other atoms.

How many valence electrons does Beryllium have?

Back

Beryllium has 2 valence electrons.

Front

What is the significance of the electron configuration?

Back

Electron configuration describes the distribution of electrons in an atom's energy levels and helps predict how an atom will react chemically.

Front

What is the maximum number of electrons in the second energy level?

Back

The second energy level can hold a maximum of 8 electrons.

Front

What element has an atomic number of 4?

Back

Beryllium has an atomic number of 4.

What is the electron configuration of Neon?

Back

The electron configuration of Neon is 1s² 2s² 2p⁶.

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.
