Consider the following statements concerning $N_2H_4$
1. It is an exothermic compound
2. It burns in air with the evolution of heat
3. It has kinetic stability
4. In reduces $Fe^{3+}$ to $Fe^{2+}$ in acidic medium
Which of the following combination is correct?
P block elements are those in which the last electron enters any of the three p-orbitals of their respective shells. Since a p-subshell has three degenerate p-orbitals each of which can accommodate two electrons, therefore in all there are six groups of p-block elements.
P block elements are shiny and usually a good conductor of electricity and heat as they have a tendency to lose an electron. You will find some amazing properties of elements in a P-block element like gallium. It’s a metal that can melt in the palm of your hand. Silicon is also one of the most important metalloids of the p-block group as it is an important component of glass.
