as we know that in the modern Periodic Table most electronegative element is fluorine which forms anions basically therefore the answer is opposite elements with low electronegative form anion usually
Atomic atoms were the first to form.
compound
This is an ionic bond.
ionic
A covalent bond.
atoms having low Ionisation enthalpy and ones having high electronegativity form ionic bond
A covalent bond forms when atoms share electrons. If two atoms have similar electronegativity values (general rule of thumb is if their electronegativity values is less than 1.67) than the two atoms are more likely to share electrons. This tends to happen between two non-metals. Ionic bonds form between two atoms with electronegativity value differences greater than 1.67. They involve a transfer of electrons. This occurs between a metal and nonmetal.
Atomic atoms were the first to form.
When the electronegativity difference of two atoms in a molecule is near zero ths molecule is nonpolar.
Atomic
Electronegativity values are a useful tool to predict what kind of bonds will form.
Atomic atoms were the first to form.
Kind of... It is a measure of the electrons on a single atom of that element.
Combinations of atoms from a metal and a non-metal form ionic bonds in most cases.
Transition metals are more likely to form covalent bonds because of their small size. Ionic bonds are preferred, but depending on circumstances (electronegativity differences, atomic size, etc.) they can form polar covalent bonds.
