Which trend decreases for metals down a group atomic radiusreactivity or melting point?

Melting points generally decrease as you go down a group for group I and group II metals. This does not apply to the transition metals. Reactivity of metals increases down a group due to a larger size and less effective charge between the nucleus and valence electrons. Atomic radius increases due to a higher principle number of electrons.

Which trend decreases for metals down a group?
Melting Point
What happens to the melting point of the alkali metals as the atom increase in size?
As we move down the group, the melting point decreases.
Why melting point decrease down the group for Alkali metals but increase for Halogens?
Because the atomic radius increases down the group 1 and decreases down the group of halogen
Melting points of alkali metals?
Alkali metals have relatively low melting points compared to the other metals. Their exact melting points depend on the element itself. But it would be useful to note that their melting points decreases down group I.
Why is there a pattern between the atomic radius and melting points within alkaline earth metals or period 2 metals?
== ==
Which decreases with increases atomic number group 2A?
Group IIA metals (alkali earth) become more reactive with non-metals as you go higher in atomic numbers.
What is a pattern of alkali metals?
if you search the periodic table and find you can see the numeric value numbers of 1 to 8 then shortly you will see the radius will increase vigourusly showing the bottom and top number at any one time then that is how to get the radius separated from the core nucleus
What is the process that results in the increase of atomic number?
The number of energy levels increase within a group. Therefor the atomic radius increases. So the atomic volume also increases.The atomic radius also increases in a group.For metals, reactivity increases down the group. For non-metals, reactivity decreases down a group.
Why do melting points get lower as you go down group 1?
There is no "generally". For alkali metals (group 1) and alkali earths (group 2) they decrease. For groups 4 to 10 they rise, for group 11 it goes down from copper to silver and then up to gold.
Which of the alkaline earth metals has the smallest electronegativity?
The electronegativityÊ of alkaline earth metals decreases as you go down the group due to increase in atomic radius. The earth alkaline metals are beryllium, magnesium, strontium, barium and radium. Radium has the smallest electronegative.
Why does sodium fluoride have a higher melting point than lithium fluoride?
Because the atomic weight of sodium is greater than the atomic weight of lithium; sodium is under lithium in the column of alkali metals.
Do group one metals have a high melting point?
No. Group 1 metals (commonly called the alkali metals) have low melting points.
