When carbon dioxide is formed, one carbon atom forms double covalent bonds with two oxygen atoms. carbon dioxide is considered a) less stable than the individual atoms because it is a gas. b) less stable than the individual atoms because it can be decomposed readily. c) more stable than individual atoms as now the outer energy levels of all atoms are filled. d) more stable than the individual atoms because together they form a more massive substance.

Ionic compounds are made of ions, and yet the overall charge of an ionic compound is neutral. why?

What are the charges of the subatomic particles by choosing the answer from the drop down menu. protons have a (+1,0,or-1). (protons,neutrons,electrons) have a 0 charge. 3.) electrons have a (+1,0,-1)

The atomic radius of sodium is 186 pm and of chlorine is 100 pm. the ionic radius for na+ is 102 pm and for cl– is 181 pm. in going from na to cl in period 3, why does the atomic radius decrease while the ionic radius increases? a. the inner electrons in the sodium cation shield its valence electrons more effectively than the inner electrons in the chloride anion do. b. the inner electrons shield the valence electrons more effectively in the chlorine atom than in the chloride anion. c. the outermost electrons in chloride experience a smaller effective nuclear charge than those in the sodium cation do. d. the outermost electrons in chloride experience a larger effective nuclear charge than those in the sodium cation do. e. monatomic ions are bigger than the atoms from which they are formed.
