Get an answer to your question “Group 7A of the periodic table contains the?1. 1. ability of a material to be drawn into a thin wire. C. Ni. 2 answers. This is due in part to their larger atomic radii and low ionization energies. Alkaline earth metals is the second most reactive group of elements in the periodic table. All the alkali metals react with water, with the heavier alkali metals reacting more vigorously than the lighter ones. Rank the metals from most reactive (1) to least reactive (3). Fluorine is the most reactive element of all in Group 7. B. Pt. The Group 2 metals become more reactive towards water as you go down the Group. For the four metals we need to know, those from Group I are more reactive than those from Group II. Group 7a of the periodic table contains thea. Because of the alkali metals' electron configuration (wants to give its one electron to another substance), they're highly reactive. There is an additional reason for the lack of reactivity of beryllium compared with the rest of the Group. The most reactive goup in the metals is the Alkali metals (Group I) The most reactive non-metal group is Group 17 or VIIA) the Halogens. MathsGee Q&A Bank, Africa’s largest personalized Math & Data Science network that helps people find answers to problems and connect with experts for improved outcomes. While sodium and potassium are almost equally abundant in earth’s crust, sodium is much more commonly found in ocean than potassium. Caesium, the fifth alkali metal, is the most reactive of all the metals. asked Aug 19, 2019 in Class X Science by aditya23 (-2,145 points) periodic classification of elements. The most reactive metal in the periodic table is francium. 18. the elements in group _____ react very violently with water? Reactivity increases as you move down the alkali metals group. Also, why do group 2 elements get more reactive? The reactivity series of metals is a chart listing metals in order of decreasing reactivity. ductility. Tantalum is the correct answer annyarias1036. Beryllium has a strong resistant layer of oxide on its surface which lowers its reactivity at ordinary temperatures. malleability. The increase in reactivity correlates to a decrease in electronegativity (increase in electropositivity.) Within each group, the metal lower down the group is more reactive. They are found in group 2 of the periodic table (formally known as group IIA). Group 1A on the periodic table; containing the most reactive metals _____6. The elements from the last period are the most reactive of all periods. Your email address will not be published. Alkali metals are in Group 1 of the periodic table and all have 1 valence electron that they readily lose to become more stable. Moderatively Reactive Metals. One may also ask, which element is least reactive in Group 7? They have the greatest tendency to lose electrons to form cations. With which name is the bond formed between these elements known and what is the class of the compound so formed known? Group 2A on the periodic table _____8. Because they are so reactive, these elements are found in compounds. AnswerAlkali metals are the most reactive metalsFrancium is the most reactive metal. Least reactive nonmetals 4. This is the opposite trend to that seen in the alkali metals in Group 1 of the periodic table . Give the symbols for: (i) A metal of group 2 (ii) A metal of group 13 (iii) Two non-metals of group 16 (iv) Most reactive non-metal group 17 ← Prev Question Next Question → 0 votes . the elements in group _____ are the most reactive metals?
