Chemistry 2.2.2. Flashcards
1
Q
Covalent bond
A
the strong electrostatic attraction between a shared pair of electrons and the nuclei of the bonded atoms.
2
Q
Dative bond
A
a covalent bond formed from 2 electrons supplied by the same atom.
3
Q
Electronegativity
A
the ability of an atom to attract the bonding electrons in a covalent bond.
4
Q
Hydrogen bond
A
a strong dipole-dipole attraction between an electron-deficient hydrogen atom of -NH, -OH or HF on one molecule and a lone pair of electrons on a highly electronegative atom containing N,O or F on a different molecule.
5
Q
Ionic bonding
A
the electrostatic attraction between positive and negative ions.
