Why does atomic size increase with reactivity for metals and decrease with reactivity for non metals?

Far as I am aware a larger atom (They get bigger going down the table) has its electrons orbiting farther from the nucleus so it has a more tenous hold on them, so they can be lost easier. A reaction is just the exchange of electrons. Most metals (or all, not sure) lose electrons in a reaction. Because non metals have to gain them in a reaction, the smaller the atom the better the grip they can get on them. (electric grip)

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.
What groups of metals is the most active?
The first cloumn in the periodic table has the most reactive elements. The elements decrease in reactivity as you go across the table. in other words alkali metals
The ability of metals to react easily with one another?
reactivity
What metals or metal compounds will not react with copper sulfate?
any metals that are below copper in the reactivity series
Which metal oxides will not react with carbon?
Metals which are above Carbon in the reactivity series, eg. Magnesium. These metals need to be extracted by electrolysis.
What happens to the chemical reactivity of alkali metals as you increase atomic numbers?
The chemical reactivity of alkali metals increase when the atomic number increase.

How can the Boer model of atomic structure be used to explain the reactivity of the alkali metals?

How does the reactivity of group 1 metals change as you go down group 1?
The reactivity increase down in the group.
What happens to the reacivity of the alkali metals as you go down the group?
the reactivity in presence of heat or another reactive element increases down the group due to increase in atomic size but in water reactivity decrease down the group due to decrease in charge density ,the smaller ion forms strong bonds with water molecules.
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.
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.
The chemical reactivity of metals tends to increase from left to right across the periodic table.?
Maybe there is no pattern...no it fals
How is the reactivity of metals related to the periodic table?
In the alkali metals column (Group 1), atomic radius increases down the group and reactivity increases. There are more shells preventing the attraction between the positive nucleus and negatively charged outer electron. (All Group 1 elements have 1 electron in their outer shell). Also, because they contain more shells down the group, the distance between the nucleus and electrons is increased. Therefore the electrostatic force is lessened between them. Both of these allow the outer electron to be lost easier to other elements, thus increasing reactivity.
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
When moving down the middle of the periodic table is there an decrease in reactivity?
yes, some transition metals like gold(Au) are almost unreactive.
What is reactivity of metals used for?
The reactivity of metals is used to transfer electricity without much electrical loss.
