Nuclear Chemistry

Alpha particle is written as?

4/2 He or α

Beta particle is written as?

0/-1 e (e-/electron)

Positron is written as?

0/+1 B

Proton is written as?

1/1 p

Neutron is written as?

1/0 n

gamma is written as?

0/0 y

What is 2/1 H → 1/1 H + ?

1/0 n (neutron_

What is 61/29 cU → 61/30 Zn + ?

0/-1 e (Beta)

210/84 Po → 206/82 Pb + ?

4/2 He (alpha)

What is alpha decay?

4/2He + m-4/a-2 X (both mass and atomic # go down) - only time mass number changes

What is beta decay?

0/-1 e +m/a+1 X (mass is neutral and atomic goes up)

What is electron capture?

0/-1 e + m/a-1 X (mass stays neutral and atomic goes down) (while beta decay adds to the atomic, the electron capture takes from the atomic number)

What is positron decay?

0/+1 e+ m/a-1 X (mass stays neutral and atomic goes down) (same reaction as electron capture but uses positron particle)
