The metals on the left side of the Periodic Table are considered to be highly reactive to air while in room temperature. The ones on the right side are less reactive and are often used for construction.
Metals are conductive because they have free-moving electrons that can carry electric current easily through the material.
They get colder.
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.
Francium is the most reactive alkali metal among francium, sodium, and potassium because it has the lowest ionization energy. Francium's reactivity increases moving down Group 1 of the periodic table. Sodium is more reactive than potassium due to sodium's lower ionization energy compared to potassium.
Compounds with freely moving electrons are typically metals. In metals, the outermost electrons are not strongly bound to any particular atom and can move freely throughout the material, leading to high electrical conductivity.
In general, moving down the middle of the periodic table results in a decrease in reactivity for transition metals. This is because as you move down a group, the valence electrons are further away from the nucleus, making it harder for the atom to lose or gain electrons and therefore lowering its reactivity.
Moving from left to right on the periodic table, the elements generall go from metal to nonmetals.
Moving down a group, the elements will have the same number if valence electrons. Tis will give them similar properties, such as the Noble Gases, or the extreme reactivity of Group I metals. Moving across a period, elements will begin to resemble each other less and share fewer properties the further apart they are in the row.
Potassium is the most reactive, followed by caesium, and then calcium. This is because reactivity generally increases moving down Group 1 of the periodic table due to decreasing ionization energy and increasing atomic size.
The Reactivity Series is a way of organising metals in a series from the most reactive to the least reactive. In introductory chemistry, the reactivity series is an empirical series of metals, in order of "reactivity" from highest to lowest. It is used to summarize information about the reactions of metals with acids and water, displacement reactions and the extraction of metals from their ores.Going from bottom to top, the metals:increase in reactivity;lose electrons more readily to form positive ions;corrode or tarnish more readily;require more energy (and different methods) to be separated from their ores;become stronger reducing agents.The most reactivePotassiumSodiumLithiumCalciumMagnesiumAluminumCarbon all below carbon up to hydrogen are extracted from their ores by heating with carbon.ZincIronLeadHydrogen all below hydrogen can be extraced from their ores using hydrogen.CopperSilver - these metals are unreactive and exist naturally. They are obtained by physical processes . e.g panning.Gold - same as silver.The least reactive
The electrons determine the reactivity. How many valence electrons there are. It is easier to lose one electron rather than three, so an element with one valence electron will be more reactive than one with three.
they become more reactive since you are moving from left to right on the Periodic Table, the elements in group 17 are the most reactive.
Atoms in the periodic table are arranged in order of increasing atomic number, which is the number of protons in an atom's nucleus. This arrangement also reflects the periodic law, where elements with similar chemical properties are grouped together in columns, known as groups or families. As you move from left to right across a period, the elements transition from metals to nonmetals, while moving down a group shows elements with similar behavior but increasing atomic size and reactivity.
they become more reactive since you are moving from left to right on the Periodic Table, the elements in group 17 are the most reactive.
Moving from left to right across a period, up to but not including the noble gases (group 18), reactivity increases. Moving down a group, the reactivity of the elements decreases. Fluorine is the most reactive element.
Reactivity, unlike other periodic trends, does not increase or decrease going across a period or up and down a group. Instead, the least reactive elements are found in the center of the d block and in group eight (the noble gases). Reactivity then increases moving to the left and right ends of the table. The most reactive elements are found in the upper right hand corner of the p block and the lower left hand corner of the s block.
