In addition to all the features of the 49g+, the 50g also includes the full equation library found in the HP 48G series (also available for the 49g+ with firmware 2.06 and above), as well as the periodic table library originally available as a plug-in card for the 48S series, as of firmware 2.15/ [6] 2.16 [11] [12] (the latest, as of 2015), and ...
Atomic radii vary in a predictable and explicable manner across the periodic table. For instance, the radii generally decrease rightward along each period (row) of the table, from the alkali metals to the noble gases; and increase down each group (column). The radius increases sharply between the noble gas at the end of each period and the ...
The atomic radius of each element generally decreases across each period due to an increasing number of protons, since an increase in the number of protons increases the attractive force acting on the atom's electrons. The greater attraction draws the electrons closer to the protons, decreasing the size of the atom.
Trend-wise, as one moves from left to right across a period in the modern periodic table, the electronegativity increases as the nuclear charge increases and the atomic size decreases. However, if one moves down in a group , the electronegativity decreases as atomic size increases due to the addition of a valence shell , thereby decreasing the ...
The size of atom; The nuclear charge; oxidation number; The screening effect of the inner shells; The extent to which the outermost electron penetrates into the charge cloud set up by the inner lying electron; In the periodic table, effective nuclear charge decreases down a group and increases left to right across a period.
Nevertheless, ionic radius values are sufficiently transferable to allow periodic trends to be recognized. As with other types of atomic radius, ionic radii increase on descending a group. Ionic size (for the same ion) also increases with increasing coordination number, and an ion in a high-spin state will be larger than the same ion in a low ...
Periodic table of the chemical elements showing the most or more commonly named sets of elements (in periodic tables), and a traditional dividing line between metals and nonmetals. The f-block actually fits between groups 2 and 3 ; it is usually shown at the foot of the table to save horizontal space.
