Bohr and Lewis Dot Models

Front

What is a valence electron?

Back

Electrons in the outer shell of an atom that are involved in chemical bonding.

Front

An element will always have the same number of what?

Back

Protons.

Front

The innermost energy level has a maximum of how many electrons?

Back

2.

Front

What does the Bohr Model represent?

Back

The structure of an atom, depicting electrons in defined orbits around the nucleus.

Front

What is the Lewis Dot Diagram used for?

Back

To represent the valence electrons of an atom and how they bond with other atoms.

Front

How many valence electrons does Boron have?

Back

3 valence electrons.

Front

What is the maximum number of electrons in the second energy level?

Back

8 electrons.

Front

What is the significance of protons in an element?

Back

Protons determine the identity of an element and its atomic number.

Front

What is the relationship between electrons and energy levels?

Back

Electrons occupy energy levels around the nucleus, with each level having a maximum capacity.

Front

What does the term 'isotope' refer to?

Back

Atoms of the same element that have the same number of protons but different numbers of neutrons.
