Emission:
write a balances nuclear equation and name the type of radioactive emmision formed
an electron emitted? THen atomic number goes up one, and atomic mass number remains the same.
so how do i do that
The subscripts must add up.
The superscripts add up.
Just like in balanced equations the coefficients must add up.
Loss of electron means nuclear charge goes up one and the mass stays the same. The periodic table will tell you the next element up.
can u do that problem for me
51 o
___CR + -1 e ---> + Y
24
2451Cr + -1oe ==>2351Y
Y must be V since that is element #23.
thanks can you do like 6 more for me
No, but I shall be happy to check your work. The goal here is to HELP you do them so you learn to do them for yourself. It won't help you for me to do them for you.
well i don't get it at all so many YOU can help me through it
OK. Just make the numbers add up.
For the Cr problem we started with, note that the subscripts on the left are 24 and -1. So algebraically, add +24 and -1 and what do we get? 23. That's how I knew the subscript on the right was 23. For the superscript, we had 50 + 0 on the left so Y must have a mass of 50 on the right. Now we know Y has an atomic number (number of protons) of 23 and it has a mass number (number of neutrons) of 50. What element is Y. The periodic table tell us that element #23 is V.
