.
States of matter and
interconversion of matter by
changing the energy
conditions.
Gas laws- Boyles law ,Charles
law and combined gas law.
Thomson’s model of an atom:
atom is like a positive sphere
where the electrons embedded
just like resins in a plum
pudding.
Rutherford’s model of an
atom: Atom has two parts –
the central nucleus and outer
shells called energy
levels.Electrons are in the
energy level in constant
motion like the planets
arounsd the sun. Protons and
neutrons are in the nucleus of
the atom.
Bohr’s model of an atom and
spectral studies.
Periodic table- Modern
periodic law.
Electronic configuration of
first 20 elements.
Trend in atomic size, ionic
radius and ionization energy.
Periodic table shows the
position of metals, non-metals
and metalloids.
Metals tend to lose electrons
and so they form cations.. nonmetals tend to gain electrons
so they form anions.
Elements in the group have
same chemical properties.
Elemnts in different groups
