Just simply put, how strongly it attracks electrons. An electron " hog " such as oxygen has an electronegativity number of 3.5 while hydrogen is at about 2.2 on the electronegativity scale.
Conductivity
electronegitivity is a electon with a negative charge that can not be altered from its original state
the tendency of the atom to pull on electrons Apex : )
there is no red light around an atom
Electronegativity is the tendency of an atom to attract the electrons of a covalent bond towards it.
Atomic number of an atom shows the number of protons in the nucleus of the atom. OR Atomic number of an atom is the number of electrons in the atom when the atom neutrally charged
Electronegativity
You think probable to atomic radius.
The electrongavitivity of an atom indicates an element is a part of electrons. The more electronegativity you have the more electrons you will need.
Prefixes are used.
The valence indicate the type of a possible compound.
