Because of its high electron affinity, gaining an electron is an endothermic process It has a smaller atomic radius than chlorine Its electron affinity is slightly lower than that of oxygen. O It has a lower electronegativity than chlorine O Its atomic...
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...
