Bohr models and Lewis dot diagrams both show the location of these subatomic particles.

What are electrons?

100
This is the center portion of the atom where the protons and neutrons are located.
What is the nucleus of an atom?
100
All matter is made up of these.
What are atoms?
100
This is a chart made up of elements.
What is the periodic table?
100
Nonmetals are located on this side of the periodic table.
What is the right side?
200

This is the primary difference between Bohr models and Lewis dot diagrams.

What is Bohr models show all electrons and Lewis dot diagrams only show valence electrons?

200
These are positively charged particles of an atom.
What are protons?
200
The number of protons in the nucleus of an atom.
What is the atomic number of an element?
200
This is a substance that cannot be broken down into simpler substances.
What is an element?
200
This element is on the "wrong" side of the periodic table, according to its characteristics.
What is hydrogen?
300

The element represented by the Bohr model in the image.

What is lithium?

300
These subatomic particles are found OUTSIDE of the nucleus.
What are electrons?
300
The number of neutrons PLUS the number of protons.
What is the mass number/atomic mass/atomic weight of an element?
300

This is the first group of metals on the periodic table.

What are alkali metals?

300

This is the 7th main group on the periodic table and includes the elements F, Cl, Br, and I.

What are the halogens?

400

A Lewis dot diagram of nitrogen would have this many valence electrons.

What are 5 electrons?

400
These subatomic particles have no charge and are found in the nucleus of an atom.
What are neutrons?
400

These have the same number of protons but different number of neutrons.

What are isotopes of an element?

400

This is the second group of elements on the periodic table.

What are alkaline earth metals?

400

This is the 8th main group on the periodic table and includes He, Ne, and Xe.

What are the noble gases?

500
This is the mistake made in this Bohr model.

What are too many electrons on the first energy level?

500

This is another name for the energy levels of an atom, where the electrons are located.

What are energy shells (or orbitals)?

500

This is how many neutrons are in an atom of uranium-234.

What are 142 neutrons?

500
This element is the only metal that is liquid at room temperature, not solid.
What is mercury?
500

This is how the periodic table is arranged - or how the periodic table is organized.

What is by increasing atomic number?
