 In Uncategorized

Elements in the same family have the same number of valence electrons? A.R. ... Do radioactive elements cause water to heat up? 2) As you move across a period, atomic radius decreases. Iridium is a chemical element with the symbol Ir and atomic number 77. Period 2 is the first period in the periodic table from which periodic trends can be drawn. Period 1, which only contains two elements (hydrogen and helium) is too small to draw any conclusive trends from it, especially because the two elements behave nothing like other s-block elements. About; Faculty; Journal Club. Lithium has the largest atomic radius in period 2 at 145 picometres. Period 2 has much more conclusive trends. Dec20.
