Does Electronegativity attract electrons
The electronegativity (EN) of an atom is a measure of an atom’s ability to attract
electrons within a chemical bond.
As you go across a period does the electronegativity increase
Yes it does
Electronegativity
Electronegativity is the periodic property of atoms that involved in chemical bonds
Process of the increasing Electronegativity
you go across a period, the electronegativity increases The number of protons (which attract the electrons) in the nucleus increases. At the same time, the number of filled, inner electron energy levels (which shield the protons from the valence electrons) remains the same Thus the electrons are pulled more tightly to the nucleus, resulting in a smaller atomic size An atom with a higher electronegativity will attract a bonding pair of electrons more strongly because the bonding pair will be pulled closer to its nucleus
The Process decreased for electro negativity
II.As you go down each group in the periodic table, the electronegativity decreases▪Valence electrons are less strongly attracted to the nucleus because the number of filled electron energy levels between the nucleus and the valence electrons increases. ▪In a compound, increasing energy levels between valence electrons and the
Ionic compound and covalent compound
Ionic compounds are comprised of a metal and a non-metal that transfer an electron, whereas a covalent compound contains atoms that share their electrons.
As a matter of fact, all bonds share electrons, however that sharing can be equal unequal
Polar covalent
an be either equal or unequal.•A bond is said to be polarcovalentwhen the electrons are slightly/moderately unequally shared between atoms.
