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.

∙ 9y agoThe reactivity of a metal decreases as we move from left to right.This is because the number of electrons are more across a period.

What does the word chemical periods mean?
The term chemical period refers to the periodic table of elements; a row of that table can be called a period. The periods follow a certain pattern starting with metals on the left, moving through nonmetals and ending at an inert gas on the right. That's why the table is said to be periodic.
When moving down a group in the periodic table what does the number of valence electrons do?
When moving down a column in the periodic table, except for the first period of column 18, the number of valence electrons remains unchanged.
How Does the metallic bond allow metals to conduct electricity?
Freely moving electrons.
What are the patterns in group 1 an 7 of the periodic table?
The alkali metals provide one of the best examples of group trends in properties in the periodic table, with well characterized homologous behavior down the group. The alkali metals show a number of trends when moving down the group - for instance, decreasing electro negativity, increasing reactivity, and decreasing melting and boiling point. Density generally increases, with the notable exception of potassium being less dense than sodium, and the possible exception of francium being less dense than cesium.The alkali metals are all highly reactive and are rarely found in elemental form in nature. As a result, in the laboratory they are stored under mineral oil. They also tarnish easily and have low melting points and densities. Potassium and rubidium possess a weak radioactive characteristic (harmless) due to the presence of long duration radioactive isotopes. Alkali metals are famous for their vigorous reactions with water, and these reactions become increasingly violent as one moves down the group. The modern explanation of the pattern of the periodic table is that the elements in a group have similar configurations of the outermost electron shells of their atoms: as most chemical properties are dominated by the orbital location of the outermost electron. There are three ways of numbering the groups of the periodic table.Elements in the same period show trends in atomic radius, ionization energy, electron affinity, and electro negativity. Moving left to right across a period, atomic radius usually decreases. This occurs because each successive element has an added proton and electron which causes the electron to be drawn closer to the nucleus. This decrease in atomic radius also causes the ionization energy to increase when moving from left to right across a period. The more tightly bound an element is, the more energy is required to remove an electron. Similarly, electro negativity will increase in the same manner as ionization energy because of the amount of pull that is exerted on the electrons by the nucleus. Electron affinity also shows a slight trend across a period. Metals (left side of a period) generally have a lower electron affinity than nonmetals (right side of a period) with the exception of the noble gases. In groups, reactivity of metals increases with atomic number because the ionization energy decreases.
Why do metals have the ability to conduct heat and electricity?
Metals are relatively good conductor of heat, because the non-localized electrons are free to transport thermal energy. Each material has an electrical conductivity. It determines the value of the electrical current when an electric potential is applied.
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.
Do the elements go from metals to nonmetals or nonmetals to metals?
Moving from left to right on the periodic table, the elements generall go from metal to nonmetals.
What happens to non metals across the periodic table?
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.
What happens to the reactivity of elements in groups as the atomic numbers increase across a period?
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.
What happens to reactivity of elements in groups labeled a as atomic numbers increase across a period?
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.
How did reactivity change within this group?
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.
How can you use the reactivity series?
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
What happens to the reactivity of elements in a group labeled A as atomic numbers increase across period?
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.
What does the horizontal placing of the elements in the periodic table signify?
It signify the group of the element. For example, the first group is called alkali metals. When it is moving from left to right of the periodic table, the atomic radius decreases, the ionization energy increases, and the electronegativity increases.
What determines an element's reactivity?
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.
What does the word chemical periods mean?
The term chemical period refers to the periodic table of elements; a row of that table can be called a period. The periods follow a certain pattern starting with metals on the left, moving through nonmetals and ending at an inert gas on the right. That's why the table is said to be periodic.
How do physical properties differ as you move across a period or down a group?
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.
