Bohr's Model of an Atom - Rutherford's model had a major drawback. It could not explain why ultimately electrons did not fall into the nucleus by taking a spiral path. This was in concurrence with the electromagnetic theory that states 'if a charged particle undergoes ..

Bohr's Atomic Model - In 1913, Neils Bohr proposed a model of an atom based on the Planck's quantum theory of radiation. The basic postulates of Bohr's theory are: An atom consists of a small, heavily positively charged nucleus around which electron..

where 'Z' is the nuclear charge, which is equal to atomic number. Although Bohr's model successfully explained the stability and the line spectrum of hydrogen, it had its limitations. They wer..

. But when an electron jumps from a lower energy level to a higher one, some energy is absorbed while some energy is emitted. When an electron jumps from a higher energy level to a lower one, the amount of energy absorbed or emitted is given by the difference of energies associated with the two lev..

According to this model, an atom can be considered as a sphere of uniformly distributed positive charge in which there are electrons distributed symmetrically. The electrons must be held by the positive charges by electrostatic forces. The mutual repulsions between the electrons are balan..

Quantum Mechanical Model of the Atom - Two new theories came to substantially modify Bohr's Atomic model. They a..

Dennis bought a circular bed of area 12.56 square feet. What is the radius of the bed, if the area is modeled by the equation, A = 3.14 r 2 , where A is the area in square feet and r is the radius in feet? => 2 or 4 or 3 or 5..

At a school, the students participating in the ROTC drill formed a circle of area 200.96 square feet. What is the radius of the circle, if the area is modeled by the equation, A = 3.14 r 2 , where A is the area in square feet and r is the radius in feet? => 8 or 7 or 1..
