using the periodic table, write a alpha, beta, or positron decay of any element.

When writing an element, use the superscript and subscript text to add in atomic mass and nuclear charge for each element. use the dash and greater then symbol for the reaction arrow.

Answer #1

Alpha Decay- it is the process through which an unstable atoms become more stable by sheding two protons and two neutrons (or a helium atom that is equivalent to alpha particle) from its nucleus, that is loss of 4 units in mass number and 2 in atomic number.

equation : zXA ====> Z-2YA-4 +  2He4

example : 90Th232 ====> 88Ra228 +  2He4

Beta Decay- it's a type of radioactive decy through which a nucleus loses a beta particle i.e. a fast energetic electron or positron with antinutrino/neutrino

equation zXA ====> Z+1YA + [beta+ or beta- ]

example   example of electron emission (β decay) is the decay of carbon-14 into nitrogen-14

6C14====> 7N14 + -1e0+  ve

Positron Decay - when a positron is lost by the nucleus, it's called positron or beta+ decay.

equation zXA ====> Z+1YA +  e+  +  ve

example 12Mg23 ====> 11Na23 + +1e0  +  ve

X is parent nucleus

Y is dauthter nucleus
Z is atomic number

A is mass number

2He4 is alpha particle

+1e0 is positron,

-1e0 is electron

ve is antineutrino

ve  is neutrino
