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...
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.
Use the periodic table to predict the valence electron configuration of all the elements of group 2 (beryllium, magnesium, calcium, strontium, barium, and radium). Given: series of elements. Asked for: valence electron configurations. Strategy: Identify the block in the periodic table to which the group 2 elements belong.
The reactivity of the group 1 metals increases as you go down the group. When a group 1 element reacts its atoms only need to lose electron, as there is only 1 electron in the outer shell. When this happens, 1+ ions are formed.
Jan 23, 2023 · The traditional system for naming the geometric isomers of an alkene, in which the same groups are arranged differently, is to name them as cis or trans. However, it is easy to find examples where the cis-trans system is not easily applied. IUPAC has a more complete system for naming alkene isomers.
Periodic Table Groups. Russian chemist Dimitry Mendeleev developed the periodic table in 1869 after finding that an element’s chemical properties depended on its atomic mass. He realized that certain properties were repeated when the elements were arranged according to their atomic masses.
A textbook states, 'The thermal stability of Group 1 carbonates is generally higher than the thermal stability of Group 2 carbonates in the same period'. Explain why Group 1 carbonates are more thermally stable than Group 2 carbonates. (3
