Answer to Question #38120 in Inorganic Chemistry for Ashique M

Question #38120
What is meant by INNER CORE of elements (Especially P BLOCK ).How it sepends upon the physical and chemical property of the element? Please give me an asnwer
Expert's answer
The inner core of an atom is also calles the nucleus. It is the very dense region consisting of protons and neutrons at the center of an atom.
An atom is surrounded by electrons. They are located on certain orbitals. There are four principle orbitals (s, p, d, and f) which are filled according to the energy level and valence electrons of the element.
The p-block is one of two blocks in the periodic table to contain nonmetals. As such, it has some of the most diverse properties of any region in the periodic table. The metals in this region of the periodic table are, in general, softer and have lower melting points than transition metals. The p-block is the only region of the periodic table to contain metalloids. In general, the farther one goes to the right, and the farther one goes up in the p-block, the less metallic the elements get; the metalloids form a diagonal line from the upper left to the lower right of the p-block. All elements in the p-block have their outermost electron in a p-subshell. Atomic size of all elements in the 'P' block, decreases as we move from 13-th to 17-th group.
