100

This property determines which group an element will be placed in.

What is number of outer shell electrons?

100

This sweet treat is the namesake for JJ Thomsons early model of the atom.

What is Plum Pudding?
100

The number of this subatomic particle is responsible for the categorisation of atoms into specific elements.

What is a proton?

100

This diagram is used to display the electron configuration of atoms.

What is a dot and cross diagram?

100

This type of substance is defined by it containing more than one element chemically joined.

What is a compound?

200

Group 7, containing elements such as iodine and chlorine also goes by this name.

What is halogens?

200

This subatomic particle was the last to be discovered.

What is the neutron?

200

This subatomic particle has the lowest relative atomic mass.

What is the electron?

200

This term, found on the periodic table, can be used to identify the amount of electrons in an atom of a given element.

What is proton number?

200

This process separated insoluble solids from a liquid.

What is filtering?

300

Group 1, also known as the alkali metals, are named as such due to their often violent reaction with this substance.

What is water?

300

Before the disovery of the the subatomic particles in the nucleus, this property was used to order early versions of the periodic table.

What is atomic weight?

300

Together, the proton and neutron determine this property of an element.

What is (relative) atomic mass?

300

This number is also the amount of electrons required to fill the first electron shell.

What is 2?
300
Crystallisation is the process used to separate these two types of substances from each other.

What are soluble solids and liquids?

400

This group of elements is entirely monatomic.

What is noble gases / group 0?

400

Often thought of as a musical term, Newlands organised his periodic table by this law, when he noticed repeating patterns in the reactions of elements. 

What is (the law of) octaves?

400

Electrons orbit the nucleus of an atom in these structures.

What are shells?

400

This sequence describes the electron configuration of a sodium atom.

What is 2.8.1?

400

This differing property allows for separation of two liquids by distillation. 

What is the boiling point?

500

Relating to the number of electron shells in an atom, this property causes the trends in reactivity down both group 1 and group 7

What is shielding?

500

During Rutherford's scattering experiment, this was fired at gold foil, leading to the discovery of the nucleus

What is an alpha particle?

500

This varient is defined by its differing number of neutrons, while still maintaining the number of protons

What is an isotope?

500

This is the objective for all atoms. Because of this, many elements undergo chemical reactions to reach this state. Noble gases, unlike the other elements, have already reached this.

What is a full outer shell?

500
This value is used to differentiate substances separated by chromatography.

What is Rf value?
