ATOM
IT IS SMALLEST UNIT OF MOLECULE
solid ,liquid , gas ,plasma, living , non-living contain basic smallest unit is know as atom.
IT IS SMALLEST UNIT OF MOLECULE
solid ,liquid , gas ,plasma, living , non-living contain basic smallest unit is know as atom.
1. Nucleus = it is canter of atom which contain A. neutron and B. proton .
2. Orbit = orbit is surrounding area of nucleus which contain C. electrons .
CHARGE ( 1.6* 10^-19 )coulomb
A. neutron = no charge
B. proton =(+)positive charge(+ 1.6* 10^-19)
C.electron =(-)negative charge (- 1.6*10^ -19)
MASS
mass is amount of mater
Mass of neutron and proton = 1.62*10^-24 gram
mass of electron = 9.11 *10^-28
WEIGHT
the weight of a body is the product of its mass and the acceleration due to gravity.
( amount of force acting on body.)
W= M * G
W= WEIGHT
M= MASS
G= GRAVITY
ATOMIC NUMBER
Atomic number = number of protons
Mass number = proton + neutron
number of neutron in atom = number of neutron - number of electron
VOLUME
Accounting for the sizes of protons, neutrons, and electrons, most of the volume of an atom—greater than 99 percent—is, in fact, empty space. Despite all this empty space, solid objects do not just pass through one another. The electrons that surround all atoms are negatively charged and cause atoms to repel one another, preventing atoms from occupying the same space. These intermolecular forces prevent you from falling through an object like your chair.
MONOATATOMIC
When any molecule have only one atom then it is called monatomic atom.
POLYATOMIC
When any molecule have two or more then two atom then it is known as polyatomic atom.
