Revision notes on 3.2.1 Group 2 Elements for the OCR A Level Chemistry syllabus, written by the Chemistry experts at Save My Exams.
The electronic configurations of the elements in group 1: The atoms of all group 1 elements have similar chemical properties and reactions because they all have one electron in their outer...
the main groups are numbered from 1 to 7 going from left to right, and the last group on the right is Group 0; the block in between Group 2 and Group 3 is where the transition metals...
This page explores the trends in some atomic and physical properties of the Group 2 elements - beryllium, magnesium, calcium, strontium and barium. You will find separate sections below covering the trends in atomic radius, first ionisation energy, electronegativity and physical properties.
Sep 19, 2016 · You have to assume constant acceleration, and as acceleration is dv/dt, you can integrate twice ( also using v=ds/dt) where s is the displacement, you will get two equations from which you may eliminate t and get the equation your professor used. Also it is v^2-u^2=2as, not (v-u) ^2=2as.
Jun 30, 2023 · Ba(s) + 2H2O(l) → Ba(OH)2(aq) +H2(g) B a (s) + 2 H 2 O (l) → B a (O H) 2 (a q) + H 2 (g) Beryllium was first identified in 1798 by Louis-Nicolas Vauquelin, while performing a chemical analysis on aluminum silicates. The element was originally named glucinum, and it was first isolated in 1828 by Antoine Bussy and Friedrich Wohler.
Sep 1, 2024 · There are total 18 different groups in Periodic table. Let me explain each of these groups in short. Alkali metals group is the very first group (group 1) on the periodic table. The elements included in the Alkali metals group are; For detailed information on Alkali metals, read the Ultimate guide on Alkali metals of periodic table.
