Bohr Models

Front

What is a Bohr Model?

Back

A Bohr Model is a diagram that represents the structure of an atom, showing electrons in specific energy levels around the nucleus.

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

What are energy levels in an atom?

Back

Energy levels are the fixed distances from the nucleus where electrons can be found, each level can hold a specific number of electrons.

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 significance of the outermost energy level?

Back

The outermost energy level determines the chemical properties and reactivity of an element.

Front

What is an electron configuration?

Back

Electron configuration is the distribution of electrons among the energy levels and sublevels of an atom.

Front

What is the difference between a neutral atom and an ion?

Back

A neutral atom has an equal number of protons and electrons, while an ion has a different number of protons and electrons, resulting in a charge.

Front

What are valence electrons?

Back

Valence electrons are the electrons in the outermost energy level of an atom that are involved in chemical bonding.

Front

What is the relationship between groups in the periodic table and electron configuration?

Back

Elements in the same group have similar electron configurations in their outermost energy levels, leading to similar chemical properties.

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.
