Looking at the same nonmetal group on the periodic table, how does the reactivity of an element in period 2 compare to the reactivity of an element in period 4? All electrons in the atom of any element determine the reactivity. New questions in Chemistry. Three factors that determine the reactivity of an element, includes: * Valence electrons (electrons losing or gaining) * If the element is a metal or nonmetal * It's oxidation state * Electronegativity. Steve O. Lv 7. You probably have already been introduced to these schemes, at SOME degree of complexity; now the electronic scheme does rationalize to an extent elemental reactivity. in group 1, all elements have one valence electron each. How many valence electrons there are. However, the number of protons in the atomic nuclei of an element determine the element's identity.

An atom in Group 1 has only a single valence electron. LilXan420. 0. Explanation:The number of valence electrons determines an element's reactivity, or how likely the element is to react with other elements. Reactivity Trend in the Periodic Table . Elements in the same group have the same number of valence electrons and similar electronic configurations. Which determines the reactivity of an alkali metal? 2: Type of element, non-metal or metal, noble gas, halogens and alkalis. These metals tarnish/corrode very easily. An element is identified by the number of protons contained in the nuclei of its atoms. The chemical properties of a group are similar because they contain same number of valence electrons and configurations. The reactivity series is the arrangement of elements according to their reactivity. Chemistry, 21.06.2019 20:00, akiib. the number of protons in an atom of the element the number of valence electrons in an atom of the element the number of neutrons in an atom of the element the number of protons and neutrons in an atom of the element. As it turns out, protons may determine the identity of an element, but electrons rule its reactivity. This tendency is called the octet rule, because the bonded atoms have eight valence electrons. What subatomic particle is used to determine the reactivity of an element? we do single replacement reactions. Sodium 2, 8, 1 —- Here, the outermost shell has been one one electron: one more than the completely filled shell. For examples, sodium and chlorine having the follows electronic configurations are highly reactive. 3: Lastly the actual overall number of electrons, because that totals to … Generally elements in Groups 1 2 and 13 to 17 tend to react to form a closed shell corresponding to the ##s^2p^6##. Hypothesis. Most elements desires to have a very stable configuration in which all their outermost shell are completely filled. Favorite Answer. chemistry. How to determine reactivity of elements from equations? And reactivity is a shell game. The number of protons in the nucleus The number of electrons in the outer energy level The number of electrons in the innermost energy level The number of neutrons in the nucleus 1 See answer c5heham8sEllab is waiting for your help. How do you tell the reactivity of a gas element? Science. Chemistry. They are the most reactive of all metals, and along with the elements in group 17, the most reactive elements. 1: The number of valence electrons, all elements want eight, so if they have eight, non-reactive, if they have 1 or 7, highly reactive. ... All the other elements in group 1 are alkali metals. These electrons determine the chemical nature of the element. Identify the element. Well, its electronic structure..... You know that chemists have gone to great lengths in proposing and describing schemes to explain the electronic structure of a given element. Its row in the table. The valence electrons in the main group or representative elements determine chemical reactivity. 0. Its atomic number. All the elements are listed in the periodic table with such details as chemical symbols. … Answer Save. What does the amount of valance electrons determine about an element? and why is zinc more reactive than iron? 1 decade ago. To determine the position of Element X in the reactivity series. its boiling and melting points the shininess of its surface the number of protons it has its ability to lose electrons 2 See answers getuabera320 getuabera320 Answer: its ability to lose electron . When a comet collides with earth, it adds material to our planet and causes great damage. Explanation: 1. (give only 1 answer) Go to this site and look for the electrons available in the outside shells. The chemical reactivity of an element is determine by which of the following? Get more help from Chegg . The elements containing only one or seven electrons in their outermost shell show greater chemical reactivity, i.e., such elements react very fast with other elements. 1 Answer. METALS. 1 Educator answer. Elements with the same number of valence electrons behave in a similar way in reactions and so are grouped together in the same column on the periodic table. an element … The reducing ability of the metals grows weaker while traversing down the series. Most of the elements … Relevance. The valency of an element determines its reactivity. say you have Zinc, Iron, Lead, Copper and silver in order of most reactive to least, but say you have them in an equation how can you determine then? An element’s positioning in … See answer Dakis is waiting for your help. Add your answer and earn points. reactivity of an element depends on its valence electron.and the number of filled electron shells. The organization of elements on the periodic table allows for predictions concerning reactivity. The elements at the top can displace elements below them from their compounds … METALS. … The metals at the top of the reactivity series are powerful reducing agents since they are easily oxidized. What three factors determine the reactivity of an element? In a reactivity series, the most reactive element is placed at the top and the least reactive element at the bottom. Thus the periodic table is … the tendency of an element to loses its electron more readily increases when going down the group,that is it is more electropositive.number of filled electronic shells increases down the group,so the force of … The group number (1A-8A) is equal to the number of valence electrons for main group elements (except Helium). Generally, elements in Groups 1, 2, and 13 to 17 tend to react to form a closed shell, corresponding to the electron configuration #s^2p^6#. Explanation: Just took the quiz. 1: The number of valence electrons, all elements want eight, so if they have eight, non-reactive, if they have 1 or 7, highly reactive. METALS The most reactive kind of metallic element is a metal from Group 1 (e.g. This tendency is called the because the bonded atoms have eight valence electrons. answer choices . The number of valence electrons is associated with the element’s reactivity. sydniestaley sydniestaley answers. How many valence electrons does molybdenum have? Explanation: Alkali metals are more reactive since they are … In group 8 for example, all the outermost shell electrons are completely in place.
