Bohr Models and Lewis Dot Diagrams

Front

What is a Bohr model?

Back

A Bohr model is a diagram that represents the arrangement of electrons in an atom, showing the nucleus at the center and electrons in circular orbits around it.

Front

What does the atomic mass of an element represent?

Back

The atomic mass of an element represents the total number of protons and neutrons in the nucleus of an atom.

Front

How many electrons can fit in the first shell of an atom?

Back

The first shell can hold a maximum of 2 electrons.

Front

What is the maximum number of electrons in the third shell of an atom?

Back

The third shell can hold a maximum of 18 electrons.

Front

What is the atomic number of an element?

Back

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

Front

How many valence electrons does Boron (atomic number 5) have?

Back

Boron has 3 valence electrons.

Front

What is a Lewis dot diagram?

Back

A Lewis dot diagram is a representation of an atom that shows its valence electrons as dots around the element's symbol.

Front

What is the significance of valence electrons?

Back

Valence electrons are important because they determine how an atom can bond with other atoms.

Front

How many electrons does potassium (K) have?

Back

Potassium has 19 electrons.

Front

What is the relationship between protons and electrons in a neutral atom?

Back

In a neutral atom, the number of protons equals the number of electrons.
