NEET

The following are the steps one must follow to draw the structure of an atom: First, find out the atomic number of the element on the periodic table, then draw a small central circle called the nucleus that includes the protons and neutrons. Next, there will be concentric circles around the nucleus for electron shells. Next, fill these shells with dots or crosses for electrons. One can fill around a maximum of 2 electrons in the first shell and a maximum of 8 in the second shell, and so on.

It talks about the atom. According to the Greek philosophers earlier, the atoms were the smallest part of matter that cannot be further divisible. Later, Dalton's atomic theory suggested that atom is the ultimate particle of matter. This theory was challenged later on by experiments done towards the end of the 19th and beginning of the 20th century. These experiments found that atoms are made up of electrons, protons and neutrons.

The following are the topics covered in this chapter: Electric Field and Field Lines, Gauss's Law, Electric Dipole, Conductors and Insulators, and Electric Flux.
