FAMOUS PPL
He is best known for his creation of the periodic table of elements. He arranged the elements based on their atomic mass and chemical properties, noticing recurring patterns and leaving gaps for elements that were yet to be discovered. His periodic table provided a framework for understanding and predicting the properties of elements, and it remains one of the most significant achievements in the history of chemistry.

Known as the "father of modern chemistry," __________ conducted rigorous experiments that led to the formulation of the law of conservation of mass and the identification of oxygen as a key element in combustion.
ANTOINE LAVOISIER
A substance composed of two or more different elements chemically bonded together in fixed proportions.

Pioneering research on radioactivity, discovering the elements polonium and radium, and the development of the theory of atomic structure.
MARIE CURIE
A combination of two or more substances that are physically intermingled but not chemically combined, with each substance retaining its individual properties.
I'm a noble gas, used in lighting, discovered in the late 19th century, my name comes from the Greek word for 'strange" and I am known for a DC superhero.
What am I?
KRYPTON
Phosphorus, Lithium, Uranium, Tin, Oxygen, Nitrogen, Iodine, Uranium, Molybdenum
PLUTONIUM
which 3 elements are liquid at room temperature (21°C)

The discovery of the structure of DNA in 1953 was made possible by ________ X-ray diffraction work at King's. Her creation of the famous Photo 51 demonstrated the double-helix structure of deoxyribonucleic acid: the molecule containing the genetic instructions for the development of all living organisms. She never got credit for her work because this photo was later stolen by Watson and Crick
Rosalind Franklin
A process in which one or more substances (reactants) are transformed into one or more different substances (products) by rearrangement of atoms.
CHEMICAL REACTION
I'm a non-metal, used in rocket propellants, discovered in the early 19th century, I exist in multiple allotropes. What am I?
PHOSPHOROUS
(SENTENCE)
Iodine, Hydrogen, Astatine, Erbium, Boron, Cobalt, Carbon, Lithium
I HATE BROCCOLI
___________is produced as a result of the decay of heavier elements, such as uranium and thorium, and it quickly decays into other elements through radioactive decay processes.
