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...

Could you please give me answers for these ? thanks 1. Atomic radius decreases as we move from left to right in the periodic table. Which of the following is the BEST explanation for this trend? a. The electrons in the valence shell increase in number and thus interact more with one another as we move from left to right. b. There is more shielding of the inner electrons as we move from left to right. c. The electrons in...
