why density of alkali metals increases down the group - Axtarish в Google
As you move down the group, each alkali metal has more protons and neutrons in its nucleus, making it heavier . Although the atoms also get larger due to the addition of electron shells, this increase in size is not enough to offset the increase in mass, so the overall density increases.
Generally, we see that in alkali metals the rate of increase of mass is greater than rate of increase of volume, therefore the density increases down the group.

Generally, we see that in alkali metals the rate of increase of mass is greater than rate of increase of volume, therefore the density increases down the group.
Hence, the density of alkali metals increases as one moves down the group. Conclusion. The alkali metals are the elements found in the first group of the ...
Its just because density is directly proportional to mass. And the mass increases faster than that of volume expect for the case of potassium which is ...
Due to their large size, the atoms of alkali metals are less closely packed. Consequently, have low density. On going down the group, both the atomic size ...
The resultant trend is that the densities of the alkali metals increase down the table, with an exception at potassium due to an unusual increase in atomic size ...
30 июн. 2023 г. · Atomic radius increases down a group, so the volume of the atoms also increases. Fewer sodium atoms than lithium atoms, therefore, can be packed ... Trends in Atomic Radius · Summarizing the trend down...
