100

Has a p+ charge and is found in the nucleus

What is a proton

100

This is the energy an object possesses because of its motion.

What is kinetic energy.

100

This is the smallest particle of an element that has the properties of that element.

What is an atom.

100

This man invented the atomic theory.

Who was John Dalton

100

I have an atomic mass of 40.078 and an atomic number of 20 so that makes me this element.

What is calcium.

200

Has electrons in orbit around the nucleus.

Energy Shell
200

The particles in a gas are in constant, ___________ motion

What is random.

200

This is composed of Mixtures (heterogeneous and homogeneous) and Pure Substances (compounds and elements)-Anything that has mass or volume is this.

What is matter.

200

All matter is composed of atoms; there is a point where the smallest piece of the matter would be an atom.

What is the atomic theory

200

These are the units used most commonly for density.

What are g/mL.

300

Has ncharge and is found in the nucleus.

What is a neutron.

300

Particles in this state are very close together, they slide past and revolve around each other

What is a liquid

300

The amount of mass in a given volume measured in g/mL or g/cm2

What is density

300

A scientific explanation of the behaivor of matter based on all matter being made of particles that possess kinetic energy.

What is the Kinetic Molecular Theory

300

If the mass of an object is 10g and the volume is 5mL, the density is this.

What is 2g/mL.

400

Has an echarge and is found in energy shells.

What is an electron.

400

In this state particles are very far apart; they move quickly, randomly, and in straight lines.

What is a gas.

400

This is the ability of matter to react with other substances (acids, oxygen, lacks reactivity, combustable)

What is a chemical property.

400

This man described the atom as a tiny, dense, positively charged core called a nucleus, where most of the mass is concentrated, around which electrons circulate at some distance, like how planets revolve around the Sun.

Who was Rutherford

400

The density of a cube is 250g/mL and it can hold a volume of 10mL. So that would make my mass this.

What is 2500g.

500

COntains the mass of the atom and contains protons and neutrons.

What is a nucleus.

500

In this state, particles are very close together; they vibrate but do not move around-strongly attracted in a rigid structure.

What is a solid

500
Can be observed or measured (texture, colour, melting point, boiling point, solubility)

What is a physical property

500

J.J. Thomson's experiments with cathode ray tubes showed this.

What is that all atoms contain tiny negatively charged subatomic particles or electrons.

500

I am the lighest element

What is hydrogen
