AP Class 10 Physical Science Chapter 8 Structure of Atom

The Class 10 Physical Science Chapter 8 Structure of Atom, discusses the structure of an atom at an atomic level. A few of the important points from the chapter are listed in the next section,

Important Points in Chapter 8 Structure of Atom

  • Bohr’s model of the atom proposed that electrons are present in a stationary state. The electron moves to a higher energy level if it absorbs energy in the form of electromagnetic energy or moves to a lower energy state by emitting energy in the form of electromagnetic energy of appropriate frequency.
  • The space around the nucleus where there is a maximum probability of finding the electron is known as the orbital.
  • The three quantum numbers l, n, ml describe the shape, energy and orientation, respectively, of an atomic orbital.
  • The arrangement of electrons in shells, subshells and orbitals in an atom is called the electron configuration.

Now let us look at a few chapter questions, to better understand the concepts discussed here.

Class 10 Science Chapter 8 Structure of Atom

  1. What information does the electronic configuration of an atom provide?
  2. How many elliptical orbits are added by Sommerfeld in third Bohr’s orbit? What was the purpose of adding these elliptical orbits?
  3. What is the absorption spectrum?
  4. Rainbow is an example for continuous spectrum – explain.
