This is because as the elements go down the group, the number of electron shells increases, and by using the density formula, mass/volume, you 'll realise that by increasing the number of electron shells, you are increasing the number of electrons, protons and neutrons as well, which obviously have masses, and thus it will increase the density as it will definitely surpass the increase in volume.

∙ 10y agoI don't know the Periodic Table but I'd guess..due to increasing numbers of Hydrogen atoms ..OR..due to increasing complexity i.o.w. 2 unique atoms increasing to..?..7 unique atoms required to form each more complex Element? I'd be interested to learn the correct answer!! Regan

∙ 13y agoIts goes up because the atoms are bigger, Neutrons, Protons and electrons

∙ 10y agoDue to increase in number of shells (orbits of electrons arround nucleus) by 1 with each of your step.

What is the density of the element chlorine?
The density of chlorine is 0.00321g/cm3. The density of the halogens or group 17 elements increases down the group, which is why bromine is liquid and astatine is a solid at room temperature.
What happens to the size of the atoms as you move down the periodic table in group 7?
Down the group, size increases. Because number of shells increases.
What happens to the reactivity as you move down group 1 in the periodic table?
Reactivity in group 1 of elements increases as we go down the group (to francium) because in the alkali metals as we go down the group number of atomic shells increases so the elements with most shells will easily release their electrons in the outer most shell.
Why hydration energy decreases down the group in periodic table?
In fact it increases down the group because ionization energy decreases down the group
What property increases going down a group in periodic table?
Atomic size, number of shells (or energy levels) and electropositivity increases down a group on the periodic table.
Why alkali metal density increase going down the group?
Atomic-volume of alkali metals increases down the group ,But increase in mass dominates over increase in volume ,since density=(mass)/(volume) ,density increases down the group
What is the density of the element chlorine?
The density of chlorine is 0.00321g/cm3. The density of the halogens or group 17 elements increases down the group, which is why bromine is liquid and astatine is a solid at room temperature.
How does density change by going down the periodic table?
Atomic radius are increase so density change by going down the periodice table
What is the heaviest elemet of the noble gases?
Down the group the density generally increases. Thus radon will be the heaviest element.
Which is true moving down a column or group in the periodic table?
Atomic radius increases down a group. Metallic character also increases down the group.
What is the trend in density as you go down the group of halogens?
The density increase down.
What happens in density of this gases as altitude increases?
Density decreases as altitude increases ... because there's less atmosphere above it to push down.
Why basic character of alkali metals increases down the group?
Basic character depends upon electron loosing tendency of an element which increases down the group,SO basic character of alkali metals increases down the group
How a liquid changes to become a solid?
As temperature goes up density goes down. As volume goes up density goes down. As mass goes up (or increases) density also increases, or in other words, it freezes.
Electro chemical series down the group increases or decreases?
It increases
Why does metallic nature increases down the group?
From top to bottom in the group the electro positivity increases so that the metallic character increases .
What is the trend in ionic character of the group 2 compounds going down the group?
The ionic character increases for group 2 compounds as we go down the group. The metallic character also increases.
