Q. Explain about Atomic Radius?
The atomic size decreases with increase in atomic number along any period in the long form of the periodic table due to increase in effective nuclear charge. Though, the decrease in atomic radius is small when the difference in electronic configuration from one element to the next is that of an additional inner electron. This is due the additional inner electron screens the size-determining outer electrons from the nucleus much better than an additional outer electron. For example, decrease in the covalent radius from Sc to Zn; i.e., across ten elements of the 3d transition series, is 19 pm. this. Decrease is almost one-third of the decrease in the covalent radius of the seven elements of s and p blocks of the period 3.

how carbon tetra-valency lead to stability?
The positive charge of an atom is: (1) Spread all over the atom (2) Distributed around the nucleus (3)Concentrated at the nucleus (4) All of these Ans: Concentr
Tempering is a heat treatment method for metals and alloys. In steels, tempering is completed to "toughen" the metal by transforming brittle marten site into bainite or a combinat
You are given a sample block of an unknown metal. The block displaces 3.24 mL of water and has a mass of 62.5429 g. What is the density of the unknown metal? What is the metal?
Atoms with the different numbers of neutrons and same atomic number are known as isotopes. The chemical properties of an element are determined by wildly the charge on the nucleus,
