MIND OVER MATTER
WHO AM I?
IT'S NOT PURELY PHYSICAL, BABY
IT'S ELEMENTAL MY DEAR
THIS IS BOHRING
100
Anything that has mass & volume
What is matter?
100
My main contribution to the atomic theory was that atoms contain electrons.
Who is Thompson?
100
Examples include: colour, ductility, structure, hardness, viscosity
What are physical properties?
100
We classify these as metals, non-metals, metalloids &families & periods & atomic number.
What are elements?
100
The arrangement of these in the first few of these are as follows: 1st =2, 2nd =8, 3rd = 8, 4th = 18. **(2 answers)**
What is how many electrons go in each of the 1st four shells of an atom?
200
amount of matter an object has
What is mass?
200
My main contribution to the atomic theory was that the nucleus contains the positive charge & most of the mass.
Who is Rutherford?
200
Examples include: flammability, corrosion, reactions with acid
What are chemical properties?
200
Properties of these elements include: shiny, malleable, ductile, good conductors, usually solids
What are metals?
200
This represents the number of protons in the nucleus.
What is the atomic number?
300
contains 2 or more pure substances
What is a mixture?
300
I created the first periodic table based on atomic mass.
Who is Mendeleev?
300
in this type of change there is a change in state but no new substance is formed.
What is a physical change?
300
These types of elements demonstrate properties of both metals & non-metals.
What are metalloids?
300
This represents the number of protons & neutrons in the nucleus.
What is the mass number?
400
a mixture made up of substances that are evenly & microsopically mixed together
What is a homogeneous mixture?
400
I believe all matter is made of atoms & compounds are created when atoms combine.
Who is Dalton?
400
This type of change results in a new substance being formed such as rust forming on a car.
What is a chemical change?
400
These types of elements are found on the right side of the periodic table.
What are non-metals?
400
This is equal to the number of protons in a neutral atom.
What is the number of electrons in an atom?
500
A mixture that is not uniform in its composition.
What is a heterogeneous mixture?
500
My main contribution to the atomic theory was that electrons are found in certain orbits.
Who is Bohr?
500
This property is an element's ability to be beaten into sheets.
What is malleability?
500
These types of elements are found on the staircase of the periodic table.
What are the metalloids?
500
This is represented by the atomic number of an element.
What is the number of protons in an atom?
