What is a Bohr diagram?

Back

A Bohr diagram is a visual representation of an atom that shows the arrangement of electrons in energy levels around the nucleus.

Front

What do the dots in a Bohr diagram represent?

Back

The dots in a Bohr diagram represent total electrons in the atom.

Front

How many electrons can the first energy level hold in a Bohr diagram?

Back

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

Front

How many electrons can the second energy level hold in a Bohr diagram?

Back

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

Front

What is the significance of valence electrons in a Bohr diagram?

Back

Valence electrons are the electrons in the outermost energy level and are important for chemical bonding.

Front

What element has 3 electrons in its Bohr diagram?

Back

Lithium (Li) has 3 electrons in its Bohr diagram.

Front

What element has 12 electrons in its Bohr diagram?

Back

Magnesium (Mg) has 12 electrons in its Bohr diagram.

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 equals the number of electrons in a neutral atom.

Front

How do you determine the number of neutrons in an atom using a Bohr diagram?

Back

The number of neutrons can be determined by subtracting the atomic number from the atomic mass.

Front

What is the maximum number of electrons in the third energy level of a Bohr diagram?

Back

The third energy level can hold a maximum of 18 electrons.
