What is true about a pure covalent bond? a. The electrons are shared equally between the atoms in the bond. b. The electrons are transferred from one atom to the other in the bond. c.The electrons are shared unequally between atoms in the covalent bond. d. The electrons are absorbed into the nucleus of one atom in the bond. Which is NOT a property of covalent compounds? a. Poor conductor of electricity in any state b. Often liquid or gas...
A covalent bond is a bond in which electrons are shared between atoms of elements
A covalent bond is a
bond in which electrons are shared between atoms of elements. A
covalent bond can be polar or nonpolar. In a nonpolar covalent
bond, the bond is between two identical atoms and the electrons are
evenly shared between the atoms.In contrast, in a
polar covalent bond, the bond is between two nonidentical atoms and
the electrons are unevenly shared between the atoms. The uneven
sharing of electrons takes place because of the difference in the
electronegativity...

Answer true or false. 1. Atoms that lose electrons to achieve a filled valence shell become cations and form ionic bonds with anions. 2. Ionic bonds tend to form between elements on the left side of the Periodic Table, and covalent bonds tend to form between elements on the right side of the Periodic Table. 3. Electronegativity is a measure of an atom's attraction for the electrons it shares in a chemical bond with another atom. 4. Fluorine, in the...
