which element results if 2 protons and 2 neutrons are ejected from a radium nucleus with atomic num 88 and mass num 226
how do i go about this
please can you help
If you can add you can do these.
88Ra226 ==>2X4 + zzYww.
Now make the numbers add. Protons must be conserved. Mass must be conserved.
Protons are the subscripts. Mass is the superscripts. I shall be happy to check your results if you wish.
After you fill in the numbers for zz and ww, you will have the information for determining X and Y. Look on the periodic table for an element with atomic number 2 for X and atomic number zz for Y.
is this right so far
88 Ra 226 ---> 2 He 4 +
cheers
im still trying to figure the zz y ww out
right, so far.
Now 88-2=??
226-4=??
Isn't this fun?
well i suppose its fun if i only knew this course lol
here goes
88 Ra 226---> 2 He 4+ 86 Rn 222
is this correct if it is thanks for your help
=
Of course it's right.
And you can check it to make sure when you finish.
Top numbers: 222 + 4 on the right adds to 226 on the left. Check.
Bottom numbers: 86 + 2 on the right adds to 88 on the left. Check.
And the periodic table tells us element number 86 is Radon, Rn. Check.
VERY GOOD!!
Now you do the same thing with the physics problem with Au you posted. Except its a proton (1P) and not an alpha particle (2He)
You're on the right track! Let's take a look at the physics problem involving gold (Au). In this case, 1 proton is being ejected from a gold nucleus.
We start with the symbol for gold, Au, and the atomic number 79. We need to subtract 1 from the atomic number to account for the ejected proton.
So, Au79 - 1P --> X?? + Y??
Now, let's consider the mass number. Gold has a mass number of 197. To conserve mass, the mass numbers on both sides of the equation must be equal.
197 - ?? = ?? + ??
To find the values for the missing numbers, you can rearrange the equation and solve for the unknowns.
?? + ?? = 197
Once you find the values for the missing numbers, look for an element on the periodic table that matches the atomic number X and atomic number Y to determine the elements.
After you've filled in the missing numbers and identified the elements, you can check your work by ensuring that the atomic numbers and mass numbers balance on both sides of the equation.
Remember, protons must be conserved, and the mass must be conserved. Good luck!
