JEE

Helium (He) is the smallest atom. It has a smaller physical size as the protons in Helium create a stronger nuclear charge to pull its electrons closer to nucleus. The hydrogen is the lightest element.

In molecules, atoms are held together by the chemical bonds, that are strong attractive forces. The main two types of chemical bonds include ionic bond and covalent bond.

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.

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. 

For JEE Main exam, the Electric Charges and Fields is an important chapter. It is a part of Electrostatics unit. The weightage of this unit is around 6-9% of the total Physics section. You should expect around 3-5 questions in this unit including the questions from the class 12 physics chapter 1.

In the medical entrance test NEET, this chapter has a moderate weightage. You can expect around 2-3 questions of this chapter that contributes to the 3-5% of the total marks in the Physics section.

As per the earlier trends, NTA is expected to release the NCHMCT JEE 2026 application form in December 2026. The registration details and application form link will be available on the official website once it is released. 

Yes, if candidates have got admission through JEE/EAMCET, they can still appear for VSAT counselling, provided they have qualified in the VSAT exam and hold a good rank. However, before finalising the college, they must compare the college based on course, fee and facilities.
