What is Nitrogen?
This notable scientist predicted undiscovered elements in the periodic table and has an element named after them.
Who is Mendeleev?
Extremely reactive metals.
What are the alkali metals?
The key concept of this theory is that atoms are the fundamental building blocks of matter.
What is the Atom Model?
Particles with a positive charge found in the nucleus.
What are protons?
This element is represented by the letter K
What is potassium?
Vertical columns of elements in the periodic table.
What are groups/families?
Extremely reactive non-metals.
What are the halogens?
This theory suggested that atoms are composed of indivisible particles that are the same size, mass, and properties.
What is the Billiard Ball Model?
The number of protons in an atom which determines the element.
What is the atomic number (Z)?
This element is also the name of the fictional planet where Superman is from.
What is Krypton?
The name given to these elements in group 1
What are the alkali metals?
Reactive metals that burn brightly, often used in fireworks.
What are the alkaline earth metals?
After discovering the electron in the cathode ray tube experiement, J.J. Thomson gave this theory which states that atoms are positive charges with negative charges embedded within it
What is the Plum Pudding Model?
The number of protons and neutrons in the nucleus of an atom, given by the symbol A.
What is the Atomic Mass (A)?
This noble gas is used in store signs which gives these signs their namesake.
What is neon?
The name given to these elements in group2
What are the Alkaline Earth Metals?
Good conductors of heat and electricity, often having high melting points.
What are the transition metals?
This theory of the atom states that atoms are mostly empty space, based on evidence from the Gold Foil Experiment.

What are electrons?
Pb is the Latin abbreviation for this metal
What is lead?
Stable gases that have a full valence shell.
What are the noble gases?
This family is the only family to contain elements that exists in all three states of matter.
What are the halogens?
The planetary model states that electrons are confined to these discrete paths around the nucleus.
What are energy levels/orbits?
Atoms containing the same number of protons, but have a different numbe of neutrons?
What are isotopes?
