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
Why boiling point of noble gases increase down in the group?
The melting and boiling points increase down the group because of thevan der Waals forces. The size of the molecules increases down the group. This increase in size means an increase in the strength of the van der Waals forces.
Does a nonmetallic character increase or decrease down a group?
Down a group, the number of shells increases, also the atomic size. Thus , the metallic character increase does increase as going DOWN a group. It is easy to remove an electron froman atom of bigger size.
Does the reactivity of elements in group 2 increase going up or down?
The reactivity is increasing goinng down in the group.
What is the trend in density as you go down the group of halogens?
The density increase down.
Does the metals decrease or increase as it moves down the group?
What numerous property of metals do you mean? REphrase the question, please, you'll never get a serious answer on this one.
How does the reactivity of group 1 metals change as you go down group 1?
The reactivity increase down in the group.

What is the trend in density as you go down the group of halogens?
The density increase down.
What is the trend in atomic mass going down a group?
The atomic mass will increase. As you go down a group in the periodic table the atomic number rises, this increase in the number of protons is accompanied by an increase in the number of neutrons to stabilise the nucleus, and both together lead to an increase in atomic mass.
In ionization energy how does the property varies within a group?
The ionization energy decrease moving down in a group.
Why do elements increase in size as you move down the periodic table?
Down the group, atomic radius increases. This is due to increase in number of shells.
Why basicity increase down the group?
It is about metals. Metal properties are increasing.
Why does the effective nuclear charge increase when moving down the first group on the periodic table?
As you go down the first group (or any group), you are adding protons and electrons. As you add more and more protons, the effective nuclear charge will increase.
