WebThe number in square brackets is the atomic mass number (and approximate atomic mass) of the most stable isotope of that element. Key Concepts and Summary The discovery of the periodic recurrence of similar properties among the elements led to the formulation of the periodic table, in which the elements are arranged in order of increasing atomic number in … WebNe. The following general trends are observed as you go across period 2 from left to right: (a) atomic number, and therefore charge on the nucleus (nuclear or core charge) increases. (b) number of valence electrons increases. (c) atomic radius decreases. (d) first ionisation energy increases. (f) electronegativity increases (excluding neon) (g ...
