The tnergy to move.

# data[].attributes.body
First, add simple vocabulary for each

# data[].attributes.body
Solids are one of the four fundamental states of matter such as stone

# data[].attributes.body
Liquids are one of the four fundamental states of matter such as

# data[].attributes.body
Gas is one of the four fundamental states of matter such as oxygen

# data[].attributes.body
changes among phase of metal

# data[].attributes.body

Something freed heat.

# data[].attributes.body
To use heat for making liquid go

# data[].attributes.body
When sth become cold, and it can become water

# data[].attributes.body
gas to soild

# data[].attributes.body

1) All matter is made of atoms. Atoms are indivisible and indestructible.
2) All atoms of a given element are identical in mass and properties
3) Compounds are formed by a combination of two or more different kinds of atoms.
4) A chemical reaction is a rearrangement of atoms.

# data[].attributes.body
The Daltonian atom argues that the smallest unit of the material world is the atom, the atom is a single, independent, can not be divided, in the chemical change to maintain a stable state, the same kind of atomic properties are also consistent. Thomson's "watermelon" atomic structure that: the atom is an even distribution of positive charge of the sphere, with negatively ...

# data[].attributes.body
The Rutherford atomic model is also known as the "atomic model", "atomic solar system model", "atomic planetary model", "atomic nucleus model", Rutherford 1911 atomic structure model. The quality of the atoms is almost entirely concentrated in the small diameter of the core area, called the core, around the core orbit around the electronic core. The nuclei are positively charged and the electrons are negatively charged.

# data[].attributes.body
A proton is a subatomic particle, symbol p or p +, with a positive electric charge of + 1e elementary charge and mass slightly less than that of a neutron.

# data[].attributes.body
The neutron is a subatomic particle, symbol n or n0, with no net electric charge and a mass slightly larger than that of a proton. Protons and neutrons, each with mass approximately one atomic mass unit, constitute the nucleus of an atom, and they are collectively referred to as nucleons.[5] Their properties and interactions are described by nuclear physics.

# data[].attributes.body
The electron is a subatomic particle, symbol e− or β−, with a negative elementary electric charge. Electrons belong to the first generation of the lepton particle family, and are generally thought to be elementary particles because they have no known components or substructure.

# data[].attributes.body
Isotopes are variants of a particular chemical element which differ in neutron number.

# data[].attributes.body
Because of the atomic reaction，atoms lose or get electronic, make it become ions

# data[].attributes.body
This is the electronic steady state，it means they don't move out

# data[].attributes.body
any of the energy levels of a physical system

# data[].attributes.body
any of a class of elementary substances

# data[].attributes.body
an element not having the character of a metal, as carbon or nitrogen.

# data[].attributes.body
a nonmetal that in combination with a metal forms an alloy.

# data[].attributes.body
When these elements are combined with elements with greater electronegativity, the valence electrons on the outermost outer layer can be opened into the second orbit and then these elements exhibit higher valence by orbital hybridization.

# data[].attributes.body
any of the group of univalent metals including potassium, sodium, lithium, rubidium, cesium, and francium, whose hydroxides are alkalis.

# data[].attributes.body
any of the group of bivalent metals

# data[].attributes.body
any of the electronegative elements

# data[].attributes.body
the action of moving.

# data[].attributes.body
have the distance and direction.

# data[].attributes.body
the distance that passed in special time.

# data[].attributes.body
the speed in a special direction.

# data[].attributes.body
The change of speed times times.

# data[].attributes.body
The way you move.

# data[].attributes.body
Different reference has  different motion

# data[].attributes.body
A body must maintain uniform, linear motion, or a stationary state until the external force forces it to change its motion.

# data[].attributes.body
The acceleration of an object is proportional to the force, inversely proportional to the mass of the object, and proportional to the reciprocal of the mass of the object; the direction of the acceleration is the same as the direction of the force.

# data[].attributes.body
The interaction and reaction between two interacting bodies are always the same size, in opposite directions, acting on the same straight line.
