Calculation of particles in atoms
Neutron number nucleon MINUS proton
The number of protons is equivalent to the number of electrons.
Relative atomic mass has no unit.
Oh ~ the definition of isotope
Have different neutrons
Quality calculation method
Add and divide by the number
Quantity of atomic abundance
Depends on its quality
This is isotope abundance
The amount of molar matter
Mass divided by molar mass
Number of atoms divided by
Constant of the quantity of matter
Equivalent to molar value
Molecules with mass
The structure of that atom
Protons and electrons
Neutrons are not charged.
It won't be attracted
The mass of electrons is too small.
That's why it's ignored
Ionization energy of atoms
The farther to the right, the bigger it is.
In the same group
The ionization energy decreases.
The larger the ionization energy, the smaller the radius.
It depends on the amount of atomic layer.
Plus the amount of protons in the atom
Don't complicate the radius of ions.
Oh ~ definition of electronegativity
Is equivalent to ionization energy.
It's just a name change.
The meaning will not change.
Ionization energy of ions
Not necessarily equal to atoms
It depends on the number of protons
Ionic bond covalent bond
Plus the metal bond
And network covalent bonds.
Which is macromolecules.
The ionic bond is coulomb force.
Covalent bonds have van der Waals forces.
Polar and nonpolar
Permanent dipole force and hydrogen bond
When molecules give electrons,
It forms a coordination bond.
Hybridization in orbit
To determine the shape.
In nonpolar molecules
The molecular space is symmetrical
In polar molecules
The resultant force is not equal to zero.
Solid, liquid, gas
The different nature of the three
Gas has the greatest energy.
The temperature of the solid is minimum.
Ideal gas equation
PV=nRT
R is the equation constant.
The volume is proportional to the mole.
redox
When the valence rises, the loss of electrons is an oxidation reaction; When the valence drops, the electrons obtained are reduction reactions.
The reaction of losing electrons is a reducing agent.
The reaction of getting electrons is oxidant.
Nothing is complicated.
Change of enthalpy change energy
Enthalpy of reaction and enthalpy of formation
The reactant is a simple substance
