The proton chemical shift in H1 NMR can be dependent on nearby groups. Select the changes that can increase the proton chemical shift. A decrease in the electronegativity of a nearby group. A decrease in the number of electronegative groups nearby. An increase in the number of electronegative groups nearby. An increase in the electronegativity of a nearby group. A decrease in distance between the proton and a nearby electronegative group. An increase in distance between the proton and a nearby electronegative group.

"a connection, a bond or common feeling between two people", or as a chemical process it stimulates love or sexual attraction

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
