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 process that results in the increase of atomic number is nuclear fusion. This occurs when two atomic nuclei combine to form a heavier nucleus, leading to an increase in atomic number. Nuclear fusion is the process that powers the sun and other stars.
What groups of metals is the most active?
The alkali metals (Group 1) are the most active metals because they have low ionization energies and readily lose their outer electron to form ions. This reactivity increases as you move down the group due to the decreasing ionization energy.
Why hydrogen is included in reactivity series?
Hydrogen is included in the reactivity series because it can act as a reducing agent in chemical reactions, displacing certain metals from their compounds. It can react with metals to form metal hydrides and can also react with non-metals like oxygen to form water. These reactions demonstrate its ability to undergo redox reactions and its position in the reactivity series.
Why is a sodium cation not likely to be a heavy metal?
A sodium cation is not likely to be considered a heavy metal because it is a light element with a low atomic number and relatively low atomic mass. Heavy metals are typically defined as metals with high atomic numbers and densities, which sodium does not exhibit.
Does hydrogen react with metals?
Hydrogen can react with metals to form metal hydrides. This reaction can occur at high temperatures or under certain conditions, and it depends on the specific metal and its reactivity with hydrogen.
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.
What causes metals to be less reactive across a period?
Metals become less reactive across a period due to an increase in ionization energy and a decrease in atomic radius. These factors make it more difficult for metals to lose electrons and form cations, resulting in decreased reactivity.
Does the metals decrease or increase as it moves down the group?
Metals tend to increase as you move down a group in the periodic table. This is because the reactivity of metals generally increases as you move down a group due to increased atomic size and lower ionization energy.
What patterns do you notice as you move down the groups on the Periodic Table?
As you move down the groups on the Periodic Table, you generally observe an increase in the number of electron shells, leading to an increase in atomic size. Additionally, there is a trend of increasing reactivity in alkali metals and decreasing reactivity in noble gases as you move down a group. The ionization energy often decreases as you move down a group due to the increase in atomic size and shielding effect.
What is the process that results in the increase of atomic number?
The process that results in the increase of atomic number is nuclear fusion. This occurs when two atomic nuclei combine to form a heavier nucleus, leading to an increase in atomic number. Nuclear fusion is the process that powers the sun and other stars.
What happens to the group 1 elements as you go down the table?
As you go down Group 1 in the periodic table, the reactivity of the elements increases due to the decrease in ionization energy and increase in atomic size. The metals become more reactive with water and air as you move down the group.
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 periodic trends of reactivity occur with the alkali metals?
Alkali metals become more reactive as you move down the group in the periodic table because atomic size increases, making it easier for the outermost electron to be lost. This is due to the decrease in ionization energy and increase in metallic character as you move down the group. Alkali metals react vigorously with water and oxygen, forming metal oxides and hydroxides.
What is the group trend in p-block element?
The p-block elements show a trend in increasing atomic size and decreasing electronegativity as you move down a group. They also exhibit an increase in metallic character and reactivity towards metals, along with a decrease in ionization energy moving down the group.
True or False The chemical reactivity of metals tends to increase from left to right across the periodic table?
False. The most chemically reactive metals are in the two leftmost columns.
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.
