Bohr Model

Front

What is the Bohr Model of the atom?

Back

The Bohr Model is a theory that describes the atom as having a small, positively charged nucleus surrounded by electrons that travel in circular orbits around the nucleus, with specific energy levels.

What is the atomic number of an element?

Back

The atomic number is the number of protons in the nucleus of an atom, which determines the element's identity and its position on the periodic table.

Front

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

Back

The number of valence electrons can be determined by looking at the group number of the element in the periodic table; for main group elements, the group number corresponds to the number of valence electrons.

Front

What is the significance of valence electrons?

Back

Valence electrons are important because they determine how an atom can bond with other atoms, influencing the chemical properties and reactivity of the element.

Front

What element has an atomic number of 4?

Back

Beryllium (Be) has an atomic number of 4.

Front

What is the maximum number of electrons that can occupy the first energy level in the Bohr Model?

Back

The maximum number of electrons that can occupy the first energy level is 2.

Front

What is the maximum number of electrons that can occupy the second energy level in the Bohr Model?

Back

The maximum number of electrons that can occupy the second energy level is 8.

Front

How many protons and electrons are in a neutral atom of chlorine (atomic number 17)?

Back

A neutral atom of chlorine has 17 protons and 17 electrons.

Front

What is the relationship between the atomic number and the number of electrons in a neutral atom?

Back

In a neutral atom, the number of electrons is equal to the atomic number.
