MATTER - Chemistry

 Ion, are atoms or molecules that have gained or lost one or more valence electrons, giving them a positive or negative charge.

Ions are formed by the addition of electrons to, or the removal of electrons from, neutral atoms or molecules or other ions; by combination of ions with other particles; or by rupture of a covalent bond between two atoms in such a way that both of the electrons of the bond are left in association with one of the formerly bonded atoms.

Atoms are electrically neutral because they have equal numbers of protons (positively charged) and electrons (negatively charged). If an atom gains or loses one or more electrons, it becomes an ion. 

If it gains one or more electrons, it now carries a net negative charge, and is thus "anionic."

If it gains one or more electrons, it now carries a net negative charge, and is thus "anionic."

Diffference Between Atom and Ion

Atom - Number of proton is equal to the number of Electron  (also we can say its neutral)

Ion - Number of Electron is not equal to the number of proton

Application of Ion 

Atom

are electrically neutral

number of proton and electron are the same.

Suspesion, Solution and Emulsion

Deliquescence refers to the property of a substance to absorb water from the air to dissolve itself and form an aqueous solution

Aqueous solution is a solution in which the solvent is water. 

Exothermic Reaction is the reaction that realease energy/heat

Endothermic Reaction is the reaction that absorb energy/heat

kindling point (plural kindling points). the lowest temperature at which a substance will spontaneously combust in a normal atmosphere 

Sacrificial protection is the protection of iron or steel against corrosion by using a more reactive metal. Pieces of zinc or magnesium alloy are attached to pump bodies and pipes.

  Molecule Bond

formation of non-metal and non-metal 

Eg: Sulfur form hexagonal ring called Sulfur-Hexa Fluoride (sikuielewa vizuri)

CaCO3 - Marble (Limestone )

CaCl2 -  salt (Inorganic Compound)

NaOH - Caustic Soda  

P₄O₁₀ - Phosphorus Pentoxide

anhydrous - mean no water
