Why does atomic radius increase down the group? Periodic Properties: The periodic table categorizes the elements according to their properties and atomic number (number of protons or electrons). Along the period (rows), the atomic number increases. Down the group (columns), chemical properties lik...

Does the periodic trend of atomic radius increase or decrease from top to bottom?Trend in Atomic Radius:The periodic trend in atomic radius depends on two factors: (1) principal quantum number and (2) effective nuclear charge. These two factors contrarily affect the atomic r...
CA catalyst accelerate rate of reaction by bringing down the activation energy DA catalyst always increases the rate of reaction.Submit Which of the following statements regarding the variation of atomic radii in the periodic table is not true? AIn a group,these is continuous decrease in size with...
Those that are grouped into families are all named after their largest member. For example, the Himalia group is named afterHimalia– a satellite with a mean radius of 85 km, making it the fifth largest moon orbiting Jupiter. It is believed that Himalia was once an asteroid that was capture...

Why does chlorine have a higher electronegativity value than krypton? What are the key points that are important in describing the periodic trends for atomic radius, first ionization energy, and electronegativity? If you are being asked which bond is most polar or least...
We use two generalizations to compare the atomic radii of elements. The more determining factor is the number of electron shells: The greater the number the bigger the atomic radius. The second factor (which we often use to compare atoms of the same period) is that the greater the atomic ...
Does the periodic trend of atomic radius increase or decrease from top to bottom? Does the periodic trend of ionization energy increase or decrease from top to bottom? For the group 6A elements, what is the trend in electronegativity with increasing atomic numbers? a. The elect...
Why does the ionization energy tend to decrease within a family of the periodic table? Rank the elements O, F, Be, N, and Li in order of increasing first ionization energy. Why does atomic radius increase going down a group, but it decreases across a period same for ...
