Can someone help me over here? I need an negative charge and also another thing is that in a question it asked me to use something that would represent an ion. I’m not sure on what to choose either Hydrogen or Helium but just please send help.

You could use a hydrogen anion which has 2 electrons.

Explanation:

An ion is an atom or molecule with a net electric charge because it has more or less electrons compared to the original atom or molecule.

An anion is a negatively charged ion.

A cation is a positively charged ion.

Normally a hydrogen atom has one proton and one electron.

So a hydrogen anion (H-) means that it has one proton and two electrons, which means the positive charge will be +1 and the negative charge will be -2.

Ultimately, giving the entire molecule a net charge of -1 because -2+1 = -1.

(I hope this helps! I am not 100% sure what's the format of this question. Like is it interactive? online? Did you draw all those electrons on the diagram? or were they given? Are the numbers given as well? or did you type those in? So I just tried my best to give you something that might work.)

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: )
