Bohr Model

Front

What is the Bohr Model?

Back

The Bohr Model is a theory of atomic structure that depicts electrons orbiting the nucleus in fixed paths or energy levels.

Front

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.

Front

How do you determine the number of valence electrons in an element?

Back

The number of valence electrons can be determined by the group number of the element in the periodic table.

Front

What is a valence electron?

Back

A valence electron is an electron that is located in the outermost shell of an atom and can participate in chemical bonding.

Front

What is the significance of the nucleus in an atom?

Back

The nucleus contains protons and neutrons, and it is the center of the atom, contributing to its mass and positive charge.

Front

How many electrons can the first energy level hold?

Back

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

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.

What is the electron configuration of Sodium (Na)?

Back

The electron configuration of Sodium is 1s² 2s² 2p⁶ 3s¹.

Front

What element has an atomic number of 4?

Back

Beryllium (Be) has an atomic number of 4.

Front

What is the relationship between energy levels and electron shells?

Back

Energy levels correspond to the shells where electrons reside, with higher energy levels being further from the nucleus.
