WebThe elements in 1A are all very reactive and form compounds in the same ratios with similar properties with other elements. Because of their similarities in their chemical properties, Mendeleev put these elements into the same group. …
WebDmitri Mendeleev developed an early Periodic Table of the 63 known elements, leaving gaps for the discovery of new elements to come. His table was enhanced by Henry Moseley who enabled today's ordering of the elements, based on the number of protons. Scientists at Lawrence Livermore Labs have synthesized new elements up to atomic number 118. WebPotassium is higher up in Group 1 of the periodic table than caesium. Suggest how the reaction between caesium and water would be distinct go the reaction between potassium and water. [1 mark]
WebOct 7, 2024 · The increase in reactivity correlates to a decrease in electronegativity (increase in electropositivity.) So, just by looking at the periodic table, you can predict lithium will be less reactive than sodium, and francium will be more reactive than cesium and all of the other elements listed above it in the element group. What Determines Reactivity?
