The missing word is 'ionic'.
ionic bond..?
An ionic bond results from the transfer of electrons from one atom to another. The atom that loses electrons becomes a positively charged ion, or cation. The atom that gains electrons becomes a negatively charged ion, or anion. The ionic bond that forms between them is the electrostatic attraction between the oppositely charged ions.
Electronegativity- attraction of the nucleus of one atom, to the electrons of another. First Ionization Energy(not within a bond)- The amount of energy required to strip one electron from another atom.
Atoms with weak electron attraction in a bond with calcium (Ca) include alkali metals such as lithium (Li), sodium (Na), and potassium (K). These atoms have only one valence electron, making it easier for them to lose or donate electrons rather than attract or share them. As a result, they tend to form ionic bonds with calcium, where calcium loses electrons and the alkali metal gains them.
An S atom has the weakest attraction for the electrons in a bond with an H atom.
Na
covalent bond
If one atom exerts a stronger pull on the electrons than the other, then we have a polar bond.
One atom has lost electrons . And the other atom has gained electrons.
The missing word is 'ionic'.
that atom has a greater attraction for electrons
The property that determines the strength of attraction of electrons in a covalent bond is referred to as electronegativity.

An ionic bond forms when one atom transfers electrons to another atom. When this occurs, the atom that loses the electrons becomes a positively charged ion and the atom that gains the electrons becomes a negatively charged ion. The oppositely charged ions form an electrostatic attraction to one another, which is the ionic bond.
