point of non-metallic monoplasm is increasing The gold and non-metallic properties of the elements (1) the number of elements in the same period is the same. So as the number of nuclear charges increases, the electrons are more likely to get electrons, from left to right, and non-...

The atoms in the second row of the periodic table (Li through Ne) illustrate the effect of electron shielding. All have a filled 1s2inner shell, but as we go from left to right across the row, the nuclear charge increases from +3 to +10. Although electrons are being added to the 2s...
The elements situated on the right-hand side of the table are electronegative. As a general rule, electronegativity increases in moving from left to right and from bottom to top. Atoms are more likely to accept electrons if their outer shells are almost full, and if they are less “shielded...
