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.
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

Learning Goal: This question reviews the format for writing an element's written symbol. Recall that written symbols have a particular format. Written symbols use a form like this: 17 In this form the mass number, 35, is a stacked superscript. The atomic number, 17, is a stacked subscript. Cl" is the chemical symbol for the element chlorine. A general way to show this form is: mass number It is also correct to write symbols by leaving off the atomic number,...
thank u so much! 6. One form of nuclear radiation, beta decay, occurs when a neutron changes into a proton, an electron, and a neutral particle called an antineutrino: n → pt + e + De, where ve is the symbol for an antineutrino. When this change happens to a neutron within the nucleus of an atom, the proton remains behind in the nucleus while the electron and neutrino are ejected from the nucleus. The ejected electron is called a...
