What does the first atomic theory states?

Matter is made up of tiny particles called atomos

100

What are the three subatomic particles and what are their differences?

Protons - positive charge

Neutrons - neutral charge

The particles of this state of matter are arranged irregularly and they take up the space of its container. What is the state of matter being described by the statement?

Liquid

200

What do we call the transformation of a material from one state to another?

Phase Change or Change of Phase

200

The first atomic model is also known as ________.

Solid Sphere Model

Explain the differences of Macroscopic, Microscopic, and Submicroscopic

Macroscopic - can be seen by the naked eye.

Microscopic - cannot be seen by the naked eye; instruments are used

Submicroscopic - cannot be observed but it can be explained through experimental evidences

400

Arrange the three states of matter according to INCREASING attractive forces in its particles.

Gas, Liquid, Solid

400

Explain the difference between Endothermic and Exothermic Reaction. Provide one example for each.

Endothermic - heat is required or absorbed

Melting, Evaporation, Sublimation

Exothermic - heat is released

Freezing, Condensation, Deposition

400

What are Ions and its types? Explain.

Ions - Charged atom

Cation - positive ion

Anion - negative ion

400

What is the value of the charge of an element that has 67 as its atomic number, and 70 as its number of electrons?

-3 or 3-

500

Explain the difference between elements and compounds. Provide one example for each.

Elements - made up of one type of atom.

Hydrogen, Oxygen, and so on.

Compounds - two or more elements.

Salt, Sugar, Carbon Dioxide, and so on.

500

This theory states that the arrangement, distribution, attractive forces, and movement of particles make the three states of matter distinct from each other.

Kinetic Molecular Energy
