elektronegatiivsemate

Elektronegatiivsemate is a term related to the chemical concept of electronegativity. Electronegativity describes the tendency of an atom to attract a shared pair of electrons (a bonding pair) towards itself. When comparing two atoms, the one with the higher electronegativity will exert a stronger pull on the electrons in a covalent bond. Therefore, "elektronegatiivsemate" can be understood as a comparative or superlative form indicating a greater degree of electronegativity.

Elements with higher electronegativity tend to be located towards the upper right of the periodic table, excluding noble gases. Fluorine is the most electronegative element. Conversely, elements with lower electronegativity are found towards the bottom left of the periodic table, with francium being the least electronegative. The difference in electronegativity between two bonded atoms is a key factor in determining the polarity of a chemical bond. If the difference is small, the bond is considered nonpolar covalent. If the difference is moderate, the bond is polar covalent, meaning the electrons are shared unequally, creating partial positive and negative charges on the atoms. A very large difference in electronegativity typically results in an ionic bond, where electrons are effectively transferred from one atom to another. Therefore, "elektronegatiivsemate" atoms play a crucial role in establishing the electronic distribution and reactivity within molecules.
