I don't know what's worse...you actually typing it, or me googling it to try and figure it out. Either way....WOW.

So did you figure it out by googling it?

Raises hand as someone who needed to google it.

LOL...I tried google, all it gave me were 2*3*7 answers. So, I asked my boyfriend. I will never ask again! lol

The isotopic numbers (top) have to be the same on both sides, so if you have Lithium-6 and 1 neutron, then the other side has to equal 7 as well. You have Helium-4 plus an electron, so you need an isotope of three.

The bottom number (the number of protons present) must also be the same. You have three on the left, so you must have 3 on the right. Remember that the electron produces a negative number. So, if you need a total of three and you have -1 and 2, you need a 2 to balance it, right?

That bottom number is an atomic number. So, whatever the number is represents the element on the periodic chart.
So...you get

(7-4) 3

X = He

(3-(-1)-2) 2

It has to be Helium, since 2 is the atomic number (the number of protons) for Helium.

I think that is right anyway.

If I were you I would trust this one......

My husband is a math prof. He was chair of the Math Dept for 15 years.

He could figure it out in his sleep but there is NO WAY he would give you the answer via the internet.

He would be more inclined to refer you to your local tutoring center.

so what's the correct answer?

I was going to leave it blank, as I never expected anyone to give a real shot at it, mostly I wanted a laugh. I need a break from the stress of the weekend and finals this week.

Thanks to eveyrone for the suggestions. I went with BarkerChickens' answer, and won't know the results 'till January.

I must say, though, I liked TerrieLacy's answer the best
